Viral Proteome Collection

DNASU is happy to announce the Viral Proteome Collection , consisting of 838 viral proteins from different infectious diseases. These clones are ready to be expressed using IVTT systems, with c-terminal GST tags for protein capture. They were used to study the interactions between infectious diseases and Type I Diabetes in Immunoproteomic Profiling of Antiviral Antibodies in New-Onset Type 1 Diabetes Using Protein Arrays

Frequently-asked questions (FAQ)

How do I search for plasmids?

DNASU has many search options to help with finding your genes and plasmids of interest:

  1. By clone identifier, such as DNASU Clone ID, Accession Number, RefSeqID, Gene symbol, or GeneID
  2. By BLAST using nucleotide sequence, amino acid sequence, Accession number or GI as the query
  3. By backbone features/functions, such as fusion protein tags, promoters, expression systems or cloning strategy
  4. By an advanced search, combining keywords, gene symbol/name, vector name, species, author name and/or publication information.

How much do plasmids cost?

We offer simple pricing on our plasmids, based on ordering one plasmid at a time, a single price for a 96-well plate of plasmids, or our pre-made collections of plasmids.


  • Individual plasmids - $99
  • 96-well plate of plasmids - $2400
  • Collections - $4.5/clone


  • Individual plasmids - $125
  • 96-well plate of plasmids - $2600
  • Collections - $7/clone

Will I need to sign an MTA?

All plasmids require an MTA. Some require a signed copy of the MTA be returned to us, however, many institutions have signed our Expedited Process MTA, essentially presigning the MTA for all orders from that institution. Check here to see if your institution has already signed up. If a signed MTA is required to complete your request, our system will send an email to you with a copy of our MTA for signature and return. For more information about our MTAs check here or email us.
