sP-Selectin BioAssay(TM) ELISA Kit, Mouse

P-selectin, also called GMP-140, CD62, or selectin P, is a 140kD adhesion molecule, expressed at the surface of activated cells, that mediates the interaction of activated endothelial cells or platelets with leukocytes. It is stored in secretory granules and expressed at the plasma membrane after cell activation. It is known to play an important role in atherosclerosis. The major ligand for P-selectin on leukocytes is P-selectin glycoprotein ligand-1 (PSGL-1). The standard product used in this kit is recombinant mouse P-Selectin, excluding intercellular P-Selectin and transmembrane domain. It has 42-709 amino acids sequence with the molecular mass of 99.1kD. As a result of glycosylation, the molecular mass of 190-200kD is revealed by SDS-PAGE. Intended Use: P-Selectin BioAssay(TM) ELISA Kit, Mouse is a sandwich ELISA for quantitative detection of mouse P-Selectin in cell culture supernates, serum and plasma (citrate).
