The World of Peptide Arrays
Peptide Arrays display a peptide library on a solid surface, usually a glass slide or a membrane. Any form of peptide library derived from an overlapping protein scan, substitution analysis or any other library of individual peptides can be immobilized on said surface. Peptide arrays are efficient tools to study a wide range of protein-protein interactions ranging from antibody epitope mapping and functional elucidation of detected peptide epitopes to the characterization of various enzyme target families.
Design your peptide library !
JPT is the market leader for peptide arrays in different applications because:
JPT assures high batch-to-batch consistency
Only JPT’s peptide microarrays contain purified peptides
Only JPT avoids de novo epitopes by applying a proprietary capping
Our different peptide array and microarray formats work for many different applications
We offer the largest selection of catalog peptide microarrays in the market; continuously updated to cover recent developments (e.g. outbreaks and viral variants)
