CD49b Monoclonal / PE-Vio770 / REA541

Product Details

Description	Clone REA541 recognizes the mouse CD49b antigen, a single-pass type I membrane protein also known as integrin alpha-2 (ITGA2). CD49b together with CD29 (ITGB1) forms the adhesion molecule very late antigen-2 (VLA-2), which binds mainly to collagens I, II, and XI. VLA-2 is responsible for adhesion of platelets and other cells to collagens, modulation of collagen and collagenase gene expression, force generation, and organization of newly synthesized extracellular matrix. It is also a receptor for laminins, collagen C-propeptides, and E-cadherin. Mice homozygous for a null mutation in the CD49b gene die very early in embryogenesis. CD49b is expressed on the vast majority of mouse NK cells and on a subset of NKT cells. It is not as mouse strain-restricted as other NK cell markers, for example, NK1.1, and is expressed by most common inbred mouse strains. Bone marrow (BM) resident memory T helper (Tʜ) cells also express CD49b and the homing of adoptively transferred BM memory Tʜ cells to BM can be efficiently blocked by antibodies to CD49b. This points to a decisive role of CD49b in the trafficking of memory Th cell precursors to the BM niches for memory Tʜ cells. \| Additional information: Clone REA541 displays negligible binding to Fc receptors.

About CD49b
This gene encodes the alpha subunit of a transmembrane receptor for collagens and related proteins. The encoded protein forms a heterodimer with a beta subunit and mediates the adhesion of platelets and other cell types to the extracellular matrix. Loss of the encoded protein is associated with bleeding disorder platelet-type 9. Antibodies against this protein are found in several immune disorders, including neonatal alloimmune thrombocytopenia. This gene is located adjacent to a related alpha subunit gene. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

About PE-Vio770
PE-Vio® 770 from Miltenyi Biotec is a red-emitting tandem fluorophore that combines pycoerythrin (PE) and Vio®770. The donor molecule, PE can be excited by the 488-nm blue, 532-nm green, or 561-nm yellow-green laser and and transfers energy to the acceptor molecule, Vio®770, which emitts light that can be captured with a 780/60 nm bandpass filter. PE-Vio®770 has an excitation peak at 565 nm and an emission peak at 775 nm and is a common alternative to PE-Cy7 and PE-H7.
