Human P-Selectin ELISA Kit

P-selectin (SELP), also called GMP-140, CD62, or selectin P, is a 140-kD 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 SELP on leukocytes is P-selectin glycoprotein ligand-1 (PSGL-1). The standard product used in this kit is recombinant human SELP, excluding intercellular SELP and transmembrane domain. It has 730 amino acids sequence with the molecular mass of 80 KDa. ScienCell's human P-Selectin ELISA Kit is based on standard sandwich enzyme-linked immunesorbent assay technology. Human P-Selectin-specific polyclonal antibodies are pre-coated onto 8 x 12 divisible strips. The human specific detection polyclonal antibodies are biotinylated. The test samples and biotinylated detection antibodies are subsequently added to the wells and then washed with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The intensity of yellow is proportional to the amount of human PSelectin captured in strips.
