Custom PepStar™ Peptide Microarrays

JPT Peptide Technologies applies its unique PepStar™ peptide microarray platform to generate customized peptide microarrays on glass slides.  Peptide microarrays (or peptide arrays) are used for characterization of enzymes , i.e. kinases, phosphatases and proteases as well as methyl, glycosyl, acetyl transferases and lysine deacetylases.
In addition, PepStar™ microarray technology also enables seromarker screening, humoral immune monitoring or elucidation of protein-protein interactions in general. The
chemically synthesized (SPOT synthesis) peptides are covalentyl bound on glass slides via a flexible linker. Chemoselective coupling ensures that PepStar™ peptide microarrays display only directed and purified peptides. Hundreds of identical copies of each peptide microarray can be prepared at unmatched prices and delivery times. We include a validated application protocol for manual or automated incubation, an annotation file (.gal file) and a software tool to view the .gal file and basic analysis functions.

Applications for PepStar™ Peptide Microarrays:

  • Screening for substrates of orphan enzymes
  • Validation & optimization of enzyme substrates
  • Elucidation of signal transduction pathways
  • Detection of contaminating enzyme activities

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
