Invitrogen™ CD182 (CXCR2) Monoclonal Antibody (eBio5E8-C7-F10 (5E8-C7-F10)), eBioscience™, Invitrogen™

Beschreibung

Description: The eBio5E8-C7-F10 monoclonal antibody reacts with human CD182 (CXCR2, IL-8Rbeta). CD182 is a 67-70 kDa member of the seven-transmembrane spanning G-protein coupled receptor (GPCR) family. CD182 is expressed as a homodimer, or a heterodimer with CD181 (CXCR1, IL-8Ralpha) and is expressed on granulocytes, NK cells, a subset of T cells, mast cells, monocytes, endothelial cells, megakaryocytes and oligodendrocytes. Binding of it's ligands, which include IL-8, NAP-2, GCP-2 and GRO-alpha, -beta and -gamma, induces several biological outcomes such as cell activation, chemotaxis, proliferation and angiogenesis. There are several functional differences between CD181 and CD182. Both receptors are able to mediate chemotaxis and intracellular calcium changes, but only CD181 mediates phospolipase D activation and respiratory burst. Furthermore, studies have shown that IL-8 predomitly mediates its effects on neutrophil function through CD181. Applications Reported: This eBio5E8-C7-F10 (5E8-C7-F10) antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBio5E8-C7-F10 (5E8-C7-F10) antibody has been tested by flow cytometric analysis of normal human peripheral blood. This can be used at less than or equal to 0.5 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.

CXCR2 is a receptor for interleukin-8, which is a powerful neutrophil chemotactic factor. It is a member of the GPCR family. Binding of IL-8 to the receptor causes activation of neutrophils. This response is mediated via a G-protein that activate a phosphatidylinositol-calcium second messenger system. This receptor binds to IL-8 with a high affinity and to GRO/MGSA and NAP-2 also with a high affinity. It has been reported to be expressed in a wide variety of tissues. ESTs have been isolated from human placenta and thymus libraries.
