Proteomics

Proteomics is the study of a cell's protein inventory at different times by protein identification and quantification. The application of mass spectrometry and more specifically LC-MS/MS has tremendously facilitated this process. JPT developed proprietary approaches for the provision of quantified custom peptides and ready-to-use products enabling protein biomarker identification and quantitation.

Testimonial

Christopher M. Colangelo, Ph.D, Yale University, USA

"As Director of the Protein Profiling at Yale Keck Biotechnology Resource Facility, I coordinated a collaboration between the Association of Biomolecular Resource Facilities (ABRF) standard proteomic research group (sPRG) and JPT Peptide Technologies to develop the ABRF cross-species SpikeMix™ Peptide Pool. The joint development turned out to be an extraordinary effective endeavor and the resulting product was qualified in more than 52 proteomics labs around the globe. I was impressed by JPT's scientific and technological capabilities as well as their enthusiasm to drive the project forward."
