Custom Peptide Libraries


At JPT Peptide Technologies, we are the experts in peptide library synthesis. With over 20 years of experience, we offer a comprehensive range of peptide libraries designed to meet the specific needs of your research. Whether you're exploring protein interactions, conducting cellular assays, or diving deep into proteomics, our custom peptide libraries are crafted to provide precise, reliable results.

What Are Peptide Libraries?

Peptide libraries are versatile collections of individual peptides, meticulously aliquoted and finished in various formats. These libraries can be designed from protein-spanning overlapping peptides, diverse structural sets, or any other peptide variations, making them invaluable tools for systematically studying biological properties. At JPT, we don’t just lead the market in peptide library synthesis; we also offer the broadest range of fill and finish formats, ensuring that you have the right tools for any application.

PepTrack™ Peptide Libraries

Our proprietary PepTrack™ Peptide Libraries are engineered specifically for cellular assays, such as T-cell assays. These peptide libraries are synthesized, purified, and analyzed to eliminate false-positive T-cell responses, prevent toxic inhibition, and extend peptide shelf life. With flexible specifications tailored to different applications, our customer support team is ready to help you choose the best peptide library specifications for your research.

Peptide ELISA

Peptide ELISA (enzyme-linked immunosorbent assay) enables analysis and screening on amino acid sequence level, e.g. mapping of epitopes or definition of protein interaction sites. Peptide ELISA therefore provides much more information than conventional ELISA.

We offer custom peptide ELISA plates with different specifications and plate options to choose from.

PRISMA

PRISMA (Protein Interaction Screen on Peptide Matrix) is a tool to systematically explore cell signal transmission. Peptides are immobilized on a membrane that is incubated with a biological sample. Interacting proteins are then identified and quantified by mass spectrometry.

ProteaseSpots

Protease Spots offer an efficient way to study protease activities and substrate specificities. Custom synthesized protease substrate peptides are immobilized on cellulose discs. The discs are delivered ready-to use in microtiter plates. During incubation with protease samples fluorescent detection can be performed at different time points.
