Custom Peptide Libraries and Peptide Pools


Peptide libraries are an efficient tool for T-cell epitope discovery, epitope mapping and validation as well as for vaccine development and many other biological screenings.




  • Peptide lengths: routinely 8-15 amino acid or 16-25 amino acid peptides
  • Scale: 2 μmol scale (expect an average yield of 1.5 mg for a 10 amino acid peptide)
  • Purity: from crude peptide to ≥98%
  • Delivery: in a 96-tube rack format as lyophilized powder in individual tubes
  • Including HPLC and MALDI MS documentation


Quality Control: Choose among 3 levels of quality control


  • Standard Level QC: Mass spectrometry of 6 of the 96 peptides in the set
  • Silver Level QC: HPLC analysis and mass spectrometry of 12 of the 96 peptides in the set
  • Gold Level QC: HPLC analysis of 10 and mass spectrometry of all peptides of the set


Our customer support is happy to assist you with the selection of the most appropriate peptide specifications for your application including peptide purity, amount, peptide modifications and analytical options.
