P-Selectin Monoclonal Antibody (Psel.KO.2.12), PE, Invitrogen™

Beschrijving

Reconstitute with 1 mL of distilled water. After reconstitution, store product undiluted at 4oC in the dark. For FACS analysis, use 10 μL of the suggested working dilution to label 1x10^6 cells in 100 μL. Mouse anti Human CD62P antibody, clone Psel.KO.2.12 recognizes the CD62P cell surface antigen, an approximately 140 kDa glycoprotein also known as P-selectin.

P-selectin (Selectin P, GMP-140, LECAM3, CD62 antigen-like family member) is a 140 kDa type 1 transmembrane glycoprotein, and is one of the most commonly studied proteins that regulate cell rolling. P-selectin is stored in the Weibel-Palade bodies of endothelial cells, as well as in a-granules of platelets. From there, it can be rapidly brought to the cell surface after exposure to thrombin, histamine, complement 5a, Ca21 ionophores, or adenosine diphosphate. P-selectin protein redistributes to the plasma membrane during platelet activation and degranulation and mediates the interaction of activated endothelial cells or platelets with leukocytes. P-selectin plays an important role in adhesive processes between leucocytes and endothelial cells, and is a calcium dependent receptor that binds to sialylated forms of Lewis blood group carbohydrate antigens found on neutrophils and monocytes. P-selectin is constitutively expressed in inflammation and contributes to atherogenesis, thrombosis and tissue destruction. Clinically, P-selectin is used to distinguish heparin induced thrombocytopenia with and without thrombosis.
