Custom Peptide Library Synthesis for Screening, Discovery & Immune Monitoring
Design and synthesize peptide libraries tailored to your assay, target sequence, screening format, scale, purity, and modification requirements — with scientific support from JPT’s peptide experts.
Which Peptide Library Do You Need?
Choose peptide library services that match your research question, assay conditions, and downstream screening workflow.
Overlapping Peptide Libraries
For epitope mapping, immune response studies, protein coverage, and functional region identification.
Cyclic & Macrocyclic Peptide Libraries
For constrained peptides, stability-focused screening, binding studies, and drug discovery programs.
Positional Scanning Peptide Libraries
For identifying active motifs, stimulating peptides, or sequence positions important for biological activity.
Micro-Scale Peptide Libraries
For high-throughput screening and early discovery projects requiring many peptides in small amounts.
Modified & Labeled Peptide Libraries
Biotinylated, fluorescent, isotope-labeled, stapled, phosphorylated, conjugated, or other specialty formats.
Custom Screening Libraries
For drug discovery, proteomics, immune monitoring, protein interaction studies, assay development, and validation.
