PepTrack™ Peptide Libraries

JPT's customized peptide libraries are optimized for:

  • Antigen-specific stimulation in T-cell assays
  • Immune monitoring
  • T-cell epitope identification
  • Development of cellular therapy and immunotherapy approaches
  • Vaccine development

We defined specific parameters for synthesis, purification and analysis that are important to avoid false positive T-cell responses or toxic inhibition of T-cells by peptide libraries and increase the shelf-life of peptides.
We offer our tailored peptide libraries of immunogenic or antigenic peptides with flexible specifications (peptide purity, amount of QC).

Please contact our customer support to discuss specifications that are best suited for your application! All peptide library production is performed in our laboratories in Berlin, Germany under strict regulations according to our ISO 9001:2015 certification.

Benefits of PepTrack™ Peptide Libraries

Testimonials for PepTrack™ Peptide Libraries

 “My group at the Virology Department of the UK Animal Health and Veterinary Laboratories Agency focuses on defining the T cell target antigens of important veterinary viral pathogens and the exploitation of this information in the development of new/improved vaccines. Our need for economic whole viral proteome spanning peptide libraries led us to JPT's PepTrack™ Peptide Libraries. The sensitivity of our cellular assays towards cytotoxic contaminants as well as impurities yielding in unwanted T-cell stimulation prompted a systematic evaluation of peptide sources. JPT turned out to be the most reliable vendor regarding both delivery time and high quality levels based on a certified Quality Management System. I am collaborating with JPT for many years and certainly recommend their services.”
Simon Graham, PhD (Virology Department of the UK Animal Health and Veterinary Laboratories Agency, Addlestone, Surrey, UK

"I have been collaborating with JPT for several years. Their unique peptide library technologies and knowledge of specific peptide requirements for T-cell assays made them a valuable, long-term partner in our efforts to develop novel adoptive immunotherapy approaches to prevent and treat viral infections post-transplant as well as for the treatment of virus and non virus-associated malignancies. Furthermore, their reagents allow us to precisely monitor and track specific T cell populations post-infusion"
Ann Leen, PhD (Baylor College of Medicine, Center for Cell and Gene Therapy, Houston, TX, USA)

“We utilize JPT’s peptide libraries and pools for T-cell epitope mapping and immune monitoring applications such as ELISPOT and ICS, as well as CFC. The combination of synthesis economy, quick turnaround time and tailored specifications are key to our success. JPT’s scientific competence is invaluable for all institutions planning to employ peptides in immuno assays for research or clinical setups."
Johannes Hampl, PhD (Anza Therapeutics, Inc Concord, CA, USA)
