PepStar™ Peptide Microarrays

JPT's unique PepStar™ peptide microarrays are high-content or multiwell peptide arrays on glass slides. Peptide arrays (or peptide chips) are used for biomarker discovery, immunomonitoring, antibody epitope mapping, multiplexed epitope mapping or for detection and validation of protein interactions. In addition, PepStar™ peptide microarray technology also enables enzyme profiling.
Chemical peptide synthesis is followed by peptide immobilization on glass slides via a flexible linker. Using chemoselective coupling, we generate peptide arrays displaying directed and covalently attached peptides. Multiple identical copies of each peptide microarray can be prepared with flexible layouts at unmatched prices and turnaround times.

Benefits of PepStar™ Peptide Microarrays

Testimonials for PepStar™ Peptide Microarrays

"The RV 144 HIV trial is considered as one of first successful HIV vaccine trials. It has become clear that the V2 loop of gp120 is an important site for immunogenicity and protection from HIV infection. The use of JPT's PepStar™ microarray technology has been very useful for the correlation of the clincial outcome with humoral immune responses. As have the cyclic peptides been from JPT to validate these findings!"
Jeff Currier, PhD, Walter Reed Army Institute, Rockville, Maryland, USA

"Over the past five years my research team has been active in the development of species-specific peptide arrays. Our ability to advance this technology into new research areas has been dependent on working with the highest quality of arrays. In this regard, JPT’s commitment to excellence has been a critical foundation for the success of our research program.  I have been consistently impressed with their customer service, technical expertise and professionalism. When it comes to peptide synthesis there are no other options for our group…JPT is the best."
Scott Napper, PhD, Vaccine and Infectious Disease Organization (VIDO), University of Saskatchewan, Canada
