Profile: Pi Proteomics, LLC is a manufacturer of peptides and antibodies. Our catalog peptides include amyloid peptides, angiotensins, cell penetrating, fibronectin fragments, tag peptides, microbial, ova peptides, prion protein fragments, ghrelin, obestatin and glucagon peptides. We are equipped with peptide synthesizers, HPLC systems, and mass spectrometers. Peptides are conjugated to carrier proteins such as BSA, limulus hemocyanin, and bovine thyroglobulin. Our maleimide-activated keyhole limpet hemocyanin (KLH ) conjugation kit contains five vials. The KLH is pre-activated using sulfo-SMCC. The activated KLH contains maleimide group that can react with the sulfhydryl group on the side chain of cysteine between pH 6.5-7.5 to form stable thioether bonds.
