Supporting Clinical Trials! - Trial Grade Peptide Libraries

Published on 17/04/2026

The transition from discovery research to clinical development is one of the most critical phases in medicinal research. Data generated in early screening and target discovery must now be translated into robust, reproducible, and regulatory-compliant tools suitable for clinical studies. This requires peptide libraries to be produced under stringent production conditions. JPT’s Trial Grade and Premium Grade peptide libraries support:

Immune monitoring and response profiling
Biomarker validation
Patient stratification
Assay standardization across trial sites

In this final newsletter, we highlight how JPT supports clinical research through Trial Grade and Premium Grade peptides.

Trial Track Peptide Libraries

As the name implies, PepTrack Trial Track is tailored to support peptide-based applications in clinical trials, ensuring that peptides used in clinical assays meet the quality and reproducibility requirements needed for reliable clinical data generation.

Applications: Antigen-specific stimulation of T-cells for immune monitoring or immunotherapy in clinical trials
Quality: For even higher quality, please check out our Clinical Peptides & Pools!
Purity: > 80%, 90%, 95% or 97% guaranteed for each peptide
Capping: Truncated peptides are capped after each synthesis step. This eliminates the major source of false positive T-cell responses, deletion peptides.
QC /QA: LC-MS for each peptide
Peptide Length: 15 aa
Amount per Peptide: 1-4mg or 5-10mg
Delivery Format: Freeze-dried in 96 tube racks
Delivery Time: 4-5 weeks
Minimum Order: 24 peptides

But wait, there is more!
