CD62E (E-selectin) Monoclonal Antibody (P2H3), eBioscience™, Invitrogen™

Description

Description: The P2H3 monoclonal antibody reacts with human CD62E, a 97-115 kDa member of the selectin family. CD62E, also known as E-selectin or endothelial-leukocyte adhesion molecule-1 (ELAM-1) is an adhesion molecule expressed by endothelial cells upon stimulation with cytokines including TNFalpha and IL-1beta. Induced expression of CD62E during inflammatory conditions is thought to mediate leukocyte rolling including the initial interaction of neutrophils with endothelium. The P2H3 monoclonal antibody also inhibits cellular adhesion to cytokine-activated endothelial cells. Applications Reported: This P2H3 antibody has been reported for use in flow cytometric analysis, immunoprecipitation, and immunohistochemical staining. Applications Tested: This P2H3 antibody has been tested by flow cytometric analysis of TNF alpha-actiavted Human Umbilical Vein Endothelial Cells (HUVEC). This can be used at less than or equal to 1 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 μm post-manufacturing filtered.

Leukocytes adhere to the blood vessel endothelium during extravasation in postcapillary venules of lymph nodes. In addition, leukocyte adhesion occurs in the capillaries and small venules at any site in the body after onset of inflammation. This response is immediate and involves a cascade of adhesion receptors. At the endothelial surface members of the selectin and immunoglobulin superfamilies participate in this cascade. Selectins are C-type cell surface lectins that play a role in leukocyte adhesion to the blood vessel wall endothelium. E-selectin (CD62E) is an endothelial cell specific selectin that is expressed only after activation with proinflammatory cytokines. In vitro experiments have shown that IL-1, TNFalpha and bacterial wall components like lipopolysaccharides induce the transcription of E-selectin in a NFkB dependent signaling cascade. E-selectin has been associated with blood vessel endothelium in diverse inflammatory situations.
