Medicinal Research with JPT’s Peptide Libraries: An Introduction to the Series
Published on 29/01/2026
Modern drug discovery starts with precision: understanding protein interactions, immune activation, and structure-function relationships. Peptide libraries are powerful tools to help researchers identify binding sites, validate targets, and design better therapeutics.
Resin-Based SPPS
Over the next coming weeks, we will show you how peptide libraries accelerate every step of the discovery pipeline: from molecular insight to translational breakthrough.
At JPT, our peptide libraries combine advanced synthesis technologies, rigorous analytics, and flexible fill & finish to ensure every library is optimized for your application.
Two Powerful Synthesis Platforms
These platforms support your work from early discovery to functional validation.
SPOT Synthesis
- Ideal for large libraries and high-throughput screening
- Fast, cost-effective, and highly scalable
- Supports diverse modifications
Resin-Based SPPS
- High purity and complex peptide capability
- Milligram to gram scale production
- Perfect for epitope mapping and translational research
Our Advanced Synthesis technologies include:
Cleaner Data Through Smart Chemistry: We apply capping after each synthesis step in SPPS to prevent truncations and false positives, thus delivering libraries with high sequence fidelity and reliable screening results.
Purity That Fits Your Application: From crude screening libraries to >95% purity peptides, every peptide comes with transparent purity reporting.
Built-In Quality Control: Each library can include tailored HPLC/UPLC and MS/MS QC, with full Certificates of Analysis — so you can trust every sequence.
Designed Around Your Workflow: We offer a wide range of modifications (biotin, fluorescent labels, phosphorylation, non-natural amino acids, cyclization, PEGylation and more) and deliver libraries ready to use in vials or plates, lyophilized or in solution.
