Peptide Libraries

Peptide libraries are collections of individual peptides aliquoted and finished in a variety of formats. They can result from protein-spanning overlapping peptides, sets of peptides with diverse structural properties, or any other peptide variation to systematically study biological properties. JPT is not only the leader providing the largest variety of peptide synthesis technologies but also maintains a massive plurality of fill and finish formats for any thinkable application.

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.

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.
