Peptrack™ Peptide Libraries

JPT Peptide Technologies is the leading provider of peptide libraries for T-cell assays and proteomic applications worldwide. Together with its partners in the vaccine industry, governmental and non-profit organizations, as well as universities JPT defined specific requirements for peptides to be used for T-cell assays in the various phases of vaccine development. These specifications were translated to a product line called PepTrack™ Peptide Libraries offering tailor made solutions for all peptide needs in vaccine development. Using its regulated environment (DIN EN ISO 9001:2008, GCLP), JPT produces more individual peptides on an annual basis than any other company worldwide.

Available PepTrack Options:

                  Fast Track                Most inexpensive source of small scale unpurified peptides for high-throughput
                                                   (proteome-wide) T-cell epitope/ biomarker discovery

                  Research Track        Milligram scale, unpurified peptides optimized for T-cell assays (reduction of false
                                                   positive T-cell responses, cross contamination and toxic contaminations) for T-cell
                                                   epitope mapping by ELISPOT, ICS, CFC etc. 

                  Discovery Track       Milligram scale peptides with guaranteed purity for T-cell assays in immune
                                                   monitoring and peptide pool generation

                  Trial Track                Milligram scale peptides with highest purity for T-cell assays in clinical trials

All PepTrack Levels are optimized towards performance in T-cell assays

Fast Track

Synthesized by JPT’s proprietary synthesis method Fast Track Peptide Libraries represent the most inexpensive source of peptides worldwide. The ability to produce tens-of-thousands of peptides within weeks offers T-cell epitope discovery, biological screening and identification of proteotypic peptides at proteome-wide levels.

Research Track

Research Track Peptide Libraries are designed for applications in T-cell assays requiring large numbers of fully analyzed peptides in quantities of 1-5mg. All peptides are fully analyzed for identity and purity by LC-MS (no MALDI-MS!). In addition, JPT’s peptide synthesis protocols are optimized to avoid contaminations and failure sequences which cause either false positive T-cell responses or toxic inhibition.

Discovery Track

Discovery Track Peptide Libraries have defined purities for applications requiring similar and specified purities of all peptides (i.e. immune monitoring). Each peptide has a guaranteed minimum specification. All peptides will be QC’d by LC-MS (not MALDI-MS!). 

Trial Track

Trial Track Peptide Libraries were designed to provide a reliable source of peptides and peptide pools for application as monitoring tools in clinical vaccination trials. All productions run in a regulated environment according to DIN EN ISO 9001:2008 & Good Clinical Laboratory Practices (GCLP) regulations. Synthesis protocols were optimized to reduce toxic contaminations as well as formation of deletion peptides and cross contaminants causing false positive T-cell responses. All peptides have guaranteed purities.
