Description
This Human P-Selectin (Granule Membrane Protein 140) Rapid ELISA Kit is intended is a fast ELISA kit, this assay takes less than 1.5 hours to detect Human P Selectin/SELP with <5pg/ml sensitivity. format: 96-well plate with removable strips. Compatible samples: cell culture supernates, serum and plasma (heparin, EDTA, citrate). This is a TMB colorimetric sandwich ELISA kit with short assay time and fast experiment set up. P Selectin/SELP tissue specificity: Stored in the alpha-granules of platelets and Weibel-Palade bodies of endothelial cells. Upon cell activation by agonists, P-selectin is transported rapidly to the cell surface. Strip well format. Reagents for up to 96 tests.
This human P-Selectin ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for P-Selectin has been precoated onto 96-well plates. Standards (NSO, W42-A771) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for P-Selectin is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human P-Selectin amount of sample captured in plate.
The capture antibody is monoclonal antibody from mouse, the detection antibody is polyclonal antibody from goat. Expression system for standard: P-selectin, 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 P-selectin on leukocytes is P-selectin glycoprotein ligand-1 (PSGL-1). The standard product used in this kit is recombinant human P-Selectin, excluding intercellular P-Selectin and transmembrane domain. It has 730 amino acids sequence with the molecular mass of 80 KDa
