A peptide array is a collection of peptides displayed on a solid surface, usually a glass slide or a membrane. Peptide arrays with immobilized peptides are used to study binding properties and functionality and kinetics of protein-protein interactions, e.g. to profile an enzyme, to map an antibody epitope or to find key residues for protein binding.

PepStar™ Peptide Microarrays
JPT's unique PepStar™ peptide microarrays on glass slides are the efficient tool for biomarker discovery, immunomonitoring, antibody epitope mapping, multiplexed epitope mapping or for detection and validation of protein interactions.
PepSpots - Peptides on Cellulose
PepSpots Peptides are membrane bound peptides synthesized directly onto a cellulose membrane. They are customized and inexpensive for antibody epitope mapping and protein-protein interaction studies and offer an easy experimental procedure, and flexible array and library formats.
Enzyme Substrate Arrays
Enzyme substrates are displayed on glass slides for incubation with your enzyme of interest. We compiled unique sets of enzyme substrate peptides for acetyltransferase and deacetylase as well as other enzymes. These specific enzyme substrate peptides are displayed on different peptide microarrays for incubation with purified enzymes or other fluids. Incubation can be performed manually or automated according to the application protocols provided.
