Peptide Antigen Database

Peptide Antigen Database

Designing a proper peptide antigen for antibody production can be challenging. Among the many important factors to consider, you need to know:

  • whether the peptide can elicit a strong immune response;
  • whether the antibody generated against the peptide antigen can recognize the endogenous protein.

GenScript's new Peptide Antigen Database can help you choose the optimal peptide antigens for antibody production. This database is a collection of optimal peptide antigen sequences predicted by our proprietary OptimumAntigen™ Design Tool, powered by the most advanced antigen design algorithm in the industry.

How to Search for the Right Peptide Antigen Database?

Search your target protein in the box below by inputting the protein name or accession number. For each protein, the database will provide you with the protein sequence and up to 3 peptide sequences with detailed antigenic information. Using these peptides, our PolyExpress™antibody services can produce high quality polyclonal antibodies with guaranteed ELISA titer of > 1:64,000 and western blot success rate of over 95%.

Example: P53_HUMAN, P04637 (UniProt Accession Number), NP_000537, P53 (protein name), Species Summary

If you enter a valid Uniprot ID, UniProt accession number or RefSeq protein ID, the system will not consider the species and reviewed settings of your query. The choices of species and reviewed settings are considered only if you query protein names, protein description or gene names.

Key Advantage

A unique feature of Genscript's Peptide Antigen Database is that up to 3 peptide antigens across the target protein sequence are identified. Given that in some instances, peptide antibodies fail to recognize the folded conformation of the native protein, generating antibodies against multiple antigens can significantly increase the success rate of endogenous protein detection. GenScript's Peptide Antigen Database is an exciting new resource for antigen selection; taking you one step closer to generating an efficient antibody optimized for your particular application.

Species Summary

This database contains more than two million proteins from 186 species.

Deliverables

  • An optimized peptide sequence for each specific protein that can be used as an antigen for antibody production;
  • Peptide quantity of 5-9 mg with >85% purity;
  • Production of 2-6 mg of polyclonal antibody for each peptide antigen (ELISA titer >1:64,000).
