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 work 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
