DNASU Registration

Q. Do I have to register?
A. You do not have to register to search the database, download vector and clone maps, or view other information. However, you do have to register and sign in before placing a request. Registration is live so you will be able to sign in as soon as you have completed on-line registration. We recommend signing in before you start searching for plasmids because not all plasmids are visible before registration and it saves a few steps later if you plan on ordering plasmids.

Q. My PI is not on the registration list. How do I register?
A. You will need to fill out information for both yourself and the PI during registration. People from the same lab will be able to find their PI on the list the next time someone registers.

Q. I am the PI in addition to being the user who will place orders. How do I register?
A. Please enter your information in both the user and PI fields during registration.

Searching for Plasmids

Q. What plasmids do you have in the repository?
The MR currently stores and distributes over 200,000 plasmids with inserts from over 600 organisms in over 100 vector backbones. You can see an overview and order our collections here or browse our collections here. More specifically the repository has:

  • >75,000 human and mouse ORF clones in part created through the ORFeome Collaboration
  • Collection of nearly 10,000 human clones in the cell free expression vectors tagged with either GST or Flag.
  • A collection of over 500 human kinases
  • A collection of over 1,400 human glyco-enzymes created as a collaboration between Drs. Kelley Moremen and Harry Gilbert at University of Georgia, The Center for Personalized Diagnostics at ASU, and Dr. Don Jarvis at University of Wyoming.
  • The complete (or almost complete) genomes of
    • Saccharomyces cerevisiae
    • Pseudomonas aeruginosa
    • Bacillus anthracis
    • Francisella  tularensis
    • Vibrio cholorae
    • Yersinia pestis
  • Protein Structure Initiative:Biology (PSI:Biology) protein expression plasmids
  • Nearly 400 plasmids containing truncation, domain swapped, or point mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) created by SGX Pharmaceuticals, Inc. in collaboration with the Cystic Fibrosis Foundation
  • A growing collection of clones used for antibody production created by the National Cancer Institute Clinical Proteomics Technologies for Cancer
  • Recombinant antibodies from the Recombinant Antibody Network
  • Smaller collections of plasmids created by individual laboratories 

Q. How do I search for plasmids?
DNASU has many search options to provide you with multiple ways to find your plasmid(s) or interest. These searches are

  1. By clone identifier, which queries the database using the DNASU Clone ID, or other IDs such as TargetTrack ID or Original Clone ID
  2. By clone features/functions, which identifies plasmids in vectors with specific properties, such as a particular tag, promoter, selectable marker, expression system or cloning strategy.
  3. By an advanced search, which is a combined query using keywords, gene symbol/name, vector name, species, author name and/or publication information.
  4. By PSI-specific criteria such as plasmids with inserts that have been documented to: (1) produce protein, (2) produce soluble protein, (3) produce purified protein, and (4) lead to a solved protein structure (by searching using PDB ID), for specific targets using the TargetTrack ID or PDB ID, or for all plasmids from a particular PSI Center.
  5. By BLAST using blastn, tblastn, or tblastx with nucleotide sequence, amino acid sequence, Accession number or GI as the query.

Q. Can I browse your plasmid collections?
A. Yes you can. We have several ways for your to browse the plasmids from DNASU:

  1. By Author: Browse by person, institution or constortium that created the plasmid.
  2. By Species: Browse by species name or type (e.g. bacteria, viruses, archea or eukaryotes)
  3. By Empty Vector: Browse by vector characteristics such as tags and promoter.
  4. By Collection: DNASU provides sets of plasmids that you can purchase at a discounted price. Browse all available special collections here.
  5. Biological Annotations: Browse for sets of plasmids with a particular function (e.g. glycoenzymes or GPCRs) or created for a particular purpose (e.g. all plasmids that were used for structural determination)
  6. PSI:Biology-Materials Repository Browse the PSI:Biology-Materials Repository by center or by biological annotation.

If you cannot find what you are looking for using our browse features, try our Search Options.

Q. Do you have a downloadable version of the sequences available in DNASU?
A. Yes here are downloadable zip files containing a FASTA-formatted file containing all available DNASU nucleotide or amino acid sequences.

Q. I did not find a plasmid of interest in your collection. Am I searching correctly?
A. There are several reasons who you may not be able to find your plasmid of interest. First, log in to ensure that you see all of the plasmids available to you.

Second, try using our most flexible search tool, the Advanced Text Search. There, you can use gene names and synonyms, author names, the part or full name of a vector, species name, PDB ID, TargetTrack ID or combinations to search plasmids. It is also helpful to use official gene names and identifiers as they appear in databases such as NCBI Entrez Gene or organism-specific databases like SGD or FlyBase.

Our BLAST search option also provides the ability to search the entire database by sequence. You provide a nucleotide or amino acid sequence, and the BLAST search will compare these sequences to the insert sequences of cDNAs in our collection. You will be provided with a list of available plasmids with similarity to your input sequence.

Finally, it is possible that your plasmid of interest isn't in the repository. However, feel free to email us for assistance searching for plasmids.

Information about our Plasmids

Q. What's "closed" vs. "fusion" format?
A. This terminology, adopted by our repository, indicates that a stop codon is present (closed) or is absent (fusion) in a cDNA or ORF insert. Fusion format clones are useful for producing C-terminally tagged versions of an ORF. For some examples that help identify clones and fusion plasmids, click here.

Q. Can I use restriction enzymes with human clones in pDNR-Dual?
A. The human pDNR-Dual master clones were generated using the InFusion reaction (Clontech) rather than an restriction enzyme (RE) cloning approach and most of the RE sites in the MCS are gone after the insert is introduced. In the resulting master clones, the HindIII and SalI sites are present so that enzyme pair can be used to liberate the insert -- but beware! There could be HindIII or SalI sites in the insert.

Q. What is the difference between a "discrepancy" and a "mutation"?
A. Discrepancy is a term created by the repository that refers to differences between the actual clone sequence and the target sequence (that is, what the researchers were trying to clone in a specific cloning effort). Discrepancies can result when the clone recovered is an isoform or naturally occurring polymorphic form of the target sequence, or from PCR, replication, or other errors. Be sure to check the insert sequence to be sure that discrepancies that were deemed 'acceptable' to the repository are also acceptable to you.

Mutations we define as changes that are known or expected to affect function. We curate an insert as containing a mutation when the insert sequence is a known mutant form (e.g. cloned from a mutant allele) or when the clone was engineered to have a mutation (e.g. in a site-specific mutagenesis effort). Please be aware that there may OR MAY NOT be experimental evidence to support the idea that a particular naturally occurring or engineered mutation results in a constitutively active, inactive, etc. form. And be further cautioned ... neither 'discrepancy' nor 'mutation' is the last word on nucleotide differences between your actual clone and the wild-type form(s). Tags can come from vectors and not be annotated as part of the insert; mutations and deletions may not be clearly annotated or detected by those who shared clones; and recombination or replication errors can change clones over time. DNA sequencing provides an inexpensive and robust means to ask if the clone you received is indeed the clone you requested and that it meets your expectations. Please perform diagnostic tests before investing a lot of time in your experiments!

Q.What are the pDNR-Dual, pDONR201, pDONR221, etc. vectors?
A. Most clones generated in the LaBaer laboratory and shared with the repository are based on successful recombinational cloning methodologies such as the Clontech Creator system (LoxP sites) or the Invitrogen Gateway system (att sites). These flexible systems allow a single sequence-verified ORF ("master" or "donor" clone) to be used to create expression constructs for a variety of different techniques via recombination (few steps) rather than restriction enzyme cloning and ligation (several steps). In general, we keep the master clones in our collection because they give the most flexibility to the largest set of users. But in some cases, we also have expression versions. "Entry" or "acceptor" vectors used in combination with master clones to create expression constructs are available from a number of different sources, including Clontech and Invitrogen. Here is the standard configuration of the majority of the pDONR plasmids created by the LaBaer lab available in DNASU. For more information about these cloning methods see our Resources.

Q. Do cDNA/ORF plasmids in your repository have 5' or 3' UTRs?
A. No. The majority of our collection (including human, yeast, and more) come from projects in which only the open reading frames (ORFs) were cloned.

Q. Can I get help identifying a large sub-group of clones bioinformatically?
A. Yes. Bioinformaticists in the Center for Personalized Diagnostics may be willing to collaborate with you to identify specific sub-groups of clones that share some property (biochemical function, sub-cellular localization, up-regulated in a tissue tested by microarray, etc.). Please contact us to initiate this kind of collaborative bioinformatics-based work. Requests are reviewed and accepted on a case-by-case basis. Please note that we make some bioinformatically organized groups of clones available for view and request on the clone collections page (for example, human kinase collections and the BC1000 genes associated with breast cancer).

Q. Who should I cite if my work with a clone requested via DNASU results in publication?
A. The people who put in the hard work to make the clone and any appropriate references should be cited! You should be able to find this information on the clone detail page (click on the CloneID to get there). Look for clone authors and PubMed IDs (vectors can also have associated authors and PubMed IDs).

As a non-profit entity based at a research institution, our ability to add and develop new clone collections to DNASU relies on grant funding. To track our resource's impact for future grant applications, we request that you also cite DNASU in any papers using plasmids from the repository.

Requests are filled in the order in which they are received. If you are part of the Expedited MTA network, your order will be filled within 10-12 business days. If you are not part of the network, your order will be filled within 10-12 business days after we have received your signed MTA. If your order is for more than 96 plasmids, please contact us for an estimated shipping date.

Q. Can I view info about the clones I requested and check request status?
A. You can always return to past requests and check request status by signing in and going to "my account" (top right of the page). Click on a specific clone order then look for the link at the bottom (# of clones) that takes you to a table of information lets you download an Excel spreadsheet with basic information about the clones.

Q. How much do plasmids cost?
A. Please see current pricing for individual clones or plates of 96 clones here. Large collections are priced separately, and the price is listed here.

Q. Why am I charged for a plasmid?
A. These nominal costs are designed to offset the handling fees associated with preparing and sending plasmids. In keeping with the terms outlined by our granting agencies, our aim is always to offset costs, never to make a profit. In addition, we make an effort to significantly reduce the per-clone costs for large collections in order to encourage high-throughput studies.

Q. How much does shipping cost?
A. There are two ways to pay for shipping: Provide us with you FedEx number. Otherwise you will be charged a flat shipping rate of $15 for domestic orders, $30 for international orders, or $250 for collections.

Terms of Purchase and Use

Q. Are there Terms of Purchase and Use for orders placed at DNASU?
A. Yes. You can find our Terms of Use and Purchase here. Please do not place an order for plasmids if you do not agree to these terms.

Q. Can I use plasmids I order from DNASU in a publication?
A. Absolutely! In fact, because we are a non-profit, we rely on grant funding to maintain our repository. Citing DNASU allows us to track our impact for these grants Please be sure to give credit to DNASU (cite our most recent publication in Nucleic Acids Research) and to the researcher who deposited the plasmid. This information can be found by clicking on the clone details page and finding the listed author.

Material Transfer Agreements

Q. Will I need to get a signature on an MTA?
A. All plasmids will need an MTA signature. Many institutions have signed our Expedited Process MTA ? essentially presigning the MTA, please email us if you are interested in learning more. If needed, we will be sure to identify the correct MTA and send it to you electronically to be signed by the appropriate official in your technology transfer office.

More specifically, if you are at an:

  • Academic/Not-for Profit Institution: Most plasmids are covered by our Standard Plasmid Transfer Agreement, a minimally restrictive MTA sent with clones. For some clones and for some institutions, however, you will have to have this MTA signed by an authorized official at your institution before we can send the clones. In a few exceptional cases, you will have to get a third-party MTA signed before we can send the clone, as all or part of the clone is covered by MTAs from more than one institution. We will email the appropriate MTA to you once your order has been placed or you can contact us for more information about MTAs, including information about how to join our 'in network' group with pre-approved MTA coverage. If you request clones and an MTA is required, the MTA will be emailed to you as a PDF file.
  • Company: Most of the clones in DNASU are available to companies and will be covered by a minimally restrictive MTA between ASU and your company. We will email the MTA after you place a request. You are also welcome to get in touch with usto review the terms before placing your request.

Q. How will I know which MTA to use?
A. All plasmids require our standard MTA at a minimum. If additional requirements are present for a particular clone, a ?special? MTA is required which covers both the standard and additional requirements. You can identify whether a special MTA will be required for the plasmid(s) you request by clicking on the CloneID number. This will bring you to a page with additional information about your plasmid, and the "Special MTA" column will indicate if any special MTA is needed. Once you order the plasmid, we will send the you appropriate MTA to be filled out and signed by both the researcher and the authorized signatory at your institution.

Q. How do I return the MTA to DNASU?
A. An original signed copy of the MTA can be returned to:

DNASU Plasmid Repository
Center for Personalized Diagnostics
Biodesign Institute
Arizona State University
1001 S. McAllister Dr.
Tempe, AZ 85287-6401

To expedited this process, email the MTA or fax the MTA to (480) 965-3051, informing us by email that you are doing so. Once we receive the signed MTA, your order will be shipped within 10-12 business days.

Q. Can we make this MTA process easier and faster?
A. YES!!! We have developed an Expedited Process MTA that your institution signs and allows all researchers at that institution to receive all plasmids from our collection with only an electronic signature. Please email us if you are interested in starting this process with your institution. For more information about the Expedited Process MTA see our recently published paper in Nucleic Acids Research.

Q. What is an Expedited Process MTA?
A. The most common concern we encounter when distributing plasmids relates to the complexity of MTA processing and the long delays that this causes.  We have sought to implement procedures that simplify and expedite the MTA process.  The concept for our Expedited Process is that we obtain an institutional MTA signature for the collection in advance.   This pre-signed MTA covers the vast majority of our collection of materials that has no appreciable intellectual property or liability issues. Once signed, any researcher from that recipient institution can request anything from the collection and receive it immediately because the institutional signature is already in place.  We have implemented this expedited process successfully for the past 3 years amongst over 80 institutions, and members of our network routinely request plasmids and receive them without delay. For more information about the Expedited Process MTA see our paper in Nucleic Acids Research.

Q. What are the advantages of using an Expedited Process MTA vs. a standard MTA?

  • Researchers do not have to get their institution to sign an MTA each time they order plasmids.
  • We can process orders faster because do not have to send MTAs for each order - this means that users receive their plasmids orders faster!
  • Plasmids with licensing concerns are dealt with using an addendum to the EP-MTA. This means that even when we add new plasmids to our collection, the EP-MTA your institution signed is still valid.

Q. Who at my institution can use this Expedited Process to receive plasmids?
A. Once the institution has signed the Expedited Process Agreement, it allows anyone at the institution to order plasmids without having to get an MTA signed. 

Q. When is the recipient institution notified that a scientist has requested materials?
A. We have two mechanisms in place to inform your office of plasmids ordered and received by researchers at your institution.  First, when the researcher orders plasmids, before personally agreeing to the terms of the MTA, they are reminded to contact the technology transfer office if there are internal regulations at your institution that they must follow.  The researcher will see this text (in bold):  "Please insure that you have complied with all of your institution's internal regulations for material transfer before placing this order."  Second, we will provide you (or a designated individual at your institution) with a report annually (or whenever you request) of the researchers who have ordered plasmids from us and what they have received.

Q. Are the special intellectual property terms available for the recipient institution to review in advance of the scientist's request for the materials? 
A. Intellectual property terms differ on a plasmid by plasmid basis.  Most of our plasmids do not have any intellectual property issues, and therefore, will be covered by out Standard Plasmid Transfer Agreement.  If there are intellectual property issues for particular plasmids, we will not use this expedited process.  Rather, we will send you our standard plasmid transfer agreement with either an addendum or letter to be signed that covers the terms for the intellectual property found within that plasmid.

We are acutely aware of third party materials, and we will not distribute any materials that have IP issues under this pre-approved MTA. If there are additional terms required by these third parties, we will distribute these materials in the "old" way by sending the researcher the MTA to be processed by the Technology Transfer Office. However, in our collection only a small percentage (<1%) have additional terms for their distribution (hence why we have initiated this expedited process).

Q. Has my institution already signed the expedited process MTA?
A. Click here to see if your institution has already approved the expedited process MTA. If not, please contact us.

Q. What can I do to get my institution to sign an Expedited Process MTA?
A. Please contact us, and we will work with you and your institution to agree to the EP-MTA. All your institution must do is fill in the information in the Expedited Process Agreement, and have both this and the Standard Plasmid Transfer Agreement signed by your institution's authorized individual.  Because we do not have to countersign the agreement, just send one copy to the following address:

DNASU Plasmid Repository
Center for Personalized Diagnostics
Biodesign Institute
Arizona State University
1001 S. McAllister Ave.
Tempe, AZ 85287-6401

Once we receive this, we will add you to our network.  If you would like to expedite this process, please feel free to email a scanned pdf of the signed documents, and your institution will immediately be added to the network.


How to Deposit Plasmids

Q. How do I deposit my plasmids?
A. Click here or contact us at for more information about depositing clones in our collection. See our slide show for an overview of the repository and the submission process. The three steps to deposit clones are:

  1. Have your institution sign the Depositors Agreement. This agreement sets the terms by which the plasmid repository will distribute your plasmids. Contact us to see if your institution has already signed a depositor agreement. Otherwise we will contact your technology transfer office to begin the process. Click here for more information about depositor agreements.
  2. Prepare the data describing the details about your clones. Because we parse the data directly into our database, we ask that the information you send us is in a particular format. We have submission forms and templates that should guide you in this process.
  3. Once we have entered your data into our database, we can accept your plasmid samples. These can be sent on dry ice either as DNA (10-15ul of at least 15ng/ul) or glycerol stocks. If you send glycerol stocks the bacteria MUST BE T1/T5 phage resistant. Once we receive your samples, we will make them available for purchase through DNASU.

Q. What types of plasmids cannot be shared with the repository?
A. Four types of plasmids cannot be added to the repository:

  1. Plasmids that require an unusual or specific bacterial host strain cannot be added, as we require that all plasmids are stored here in a phage-resistant DH5-alpha-like host strain, in order to maintain the integrity of the collection as a whole.
  2. Plasmids that are identical to material that is commercially available cannot be added to our collection.
  3. Plasmids that are hazardous or legally restricted for distribution cannot be added to the repository. This includes the toxins and pathogenicity genes from controlled organisms, however all other genes from controlled organisms are fine.
  4. Plasmids that you do not have the right to distribute (for example, plasmids you received from another researcher and/or made by another person and/or protected by a patent, licensing agreement, etc.) cannot be shared with us unless permission is also granted by any and all relevant third parties. Sometimes this extends even to modified forms of a plasmid. In general, you can share plasmids that you made or made significant modifications, but you cannot share unmodified forms of something you got from another researcher or a company.

Q. How are plasmids stored and handled after I share them?
A. When you share plasmids with the repository, we transform them into a phage-resistant bacterial host strain, single colony isolate, and create working and archival glycerol stocks. These are stored in conventional -80 degree freezers (archival copies) or in the fully automated Brooks BioStorefreezer storage system, in which working samples are stored in individually 2D barcode-labeled tubes for automated retrieval and array in any format. Information is carefully curated by PhD-level scientists and entered into the DNASU database.

Depositor Agreements

Q. What is a Depositors Agreement?
A. The Depositors Agreement sets forth the terms that allow the PSI:Biology-Materials Repository to distribute the plasmids that PSI researchers deposit. Here is our standard Depositor Agreement.

Q. Why is a Depositors Agreement needed?
A. To put this agreement in context, the DNASU plasmid repository and the PSI:Biology-MR contains both large and small collections of plasmids deposited by both for-profit and not for-profit institutions. Because we manage so many collections, it would be impossible to keep track of separate agreements or specialized provisions within agreements from individual institutes.  Thus, we found we needed a universal agreement, which evolved into the Depositor Agreement.

Q. Why can’t we just use a universal MTA (UB-MTA)?
A. At first blush, we know it is tempting to ask, "Why do we need a Depositor Agreement - why can't we just use a standard MTA?"  This is not possible, because virtually all MTAs expressly prohibit the recipient of the material from further distributing it.   Moreover, because MTAs assume that there will be no further distribution, they do not address critical liability and indemnification issues.  We specifically explored the possibility of using the UB-MTA and found that it would not work.  First, because it is an MTA, it is not designed for use by a distributor - it is meant to accompany material that is provided by the institution that produced the material. Moreover, in our experience, use of the UB-MTA had other problems; the document is long, restrictive and not well-recognized overseas.

Q. What should I do if I want to deposit plasmid(s) that contain features that have third party intellectual property?
A. This is not a problem, although we will need to come to an agreement with the entity that controls the feature of the plasmid(s) that is covered by intellectual property laws. This agreement will provide the protocol for distribution of this plasmid and possibly an addendum to the EP-MTA. In many cases these so-called "third party" issues only apply if a company buys that plasmid. In this case, the most common outcome is that the company will have to obtain a license from the third party before receiving the particular plasmid(s). Contact your Office of Technology Transfer or Office of General Counsel if you are unsure if your plasmids contain intellectual property.

Q. Who has signed the Depositors Agreement?
A. Click here to see who has signed the Depositors Agreement.  If your institution has not yet signed, please contact us so we can work together to expedite this process.
