CD49b (Integrin alpha 2) Monoclonal Antibody (P1H5), APC, eBioscience™, Invitrogen™

Description

Description: This P1H5 monoclonal antibody reacts with human CD49b, which is also known as integrin alpha 2. Integrins constitute a family of cell surface receptors that mediate adhesion between cells or between a cell and the extracellular matrix. These proteins are heterodimers consisting of two distinct subunits, alpha and beta. Integrins are expressed on hematopoietic, non-hematopoietic, and cancer cells. Integrin-mediated adhesion is regulated by changes in ligand affinity (or activation), cell shape, and integrin clustering and diffusion. Integrin alpha 2 forms a complex with the common beta 1 subunit to form the alpha2beta1 integrin, which binds type I collagen and laminin. Moreover, studies suggest that this complex suppresses metastasis in cancer and participates in T cell costimulation by activating the MAPK and PI3K pathways. The P1H5 monoclonal antibody has been reported to inhibit adhesion of fibroblasts and platelets to collagen. Crossblocking studies indicate that P1H5 and eBioY418 recognize different epitopes. Applications Reported: This P1H5 antibody has been reported for use in flow cytometric analysis. Applications Tested: This P1H5 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.125 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. Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser. Filtration: 0.2 μm post-manufacturing filtered. GTP-binding proteins (G-proteins) play a critical role in signal transduction by coupling receptors to effectors. The intracellular consequences of G-protein activation include second messenger generation, protein phosphorylation, ion channel activation, gene induction, cell growth, and differentiation. Gi belongs to the pertussis toxin sensitive G-proteins. Gi consists of three different subtypes of a-subunits (ai1, ai2 and ai3).
