Product Details anti-ITGA2 Antibody

Brand: BD Pharmingen™

Characteristics: The rat anti-mouse CD49b antibody (clone DX5) reacts with the integrin α2 chain (CD49b), a 150 kDa transmembrane glycoprotein that non-covalently associates with CD29 (integrin β1), to form the integrin α2β1 complex known as VLA-2. The rat anti-mouse CD49b antibody (clone DX5) has been reported to identify the majority of NK cells and a small T-cell subpopulation in most strains (e.g., A/J, AKR, BALB/c, C3H/HeJ, C57BL/6, C57BL/10, C57BR, C58, CBA/Ca, DBA/1, DBA/2, SJL, SWR, 129/J, but not NOD). It has also been observed that this antibody recognizes platelets, which express high levels of CD49b. Multi-parameter flow cytometric analysis has demonstrated that most lymphocytes which express NK-1.1 (NKR-P1B and NKR-P1C), as detectable by mouse anti-mouse NK-1.1 antibody (clone PK136), also express the DX5 antigen. Small DX5+ NK-1.1- and DX5- NK-1.1+ subsets are found, especially among the CD3-positive population. Some CD49b+ NK cells have been reported to gradually lose reactivity with the rat anti-mouse CD49b antibody (clone DX5) when cultured in the presence of recombinant human IL-2, and the resulting DX5- cells have weakened cytotoxic activity when compared to the remaining DX5+ cells, indicating that the DX5 antibody distinguishes functional subsets of NK cells. No activation or blocking activity of the rat anti-mouse antibody (clone DX5) has been observed while staining of splenic NK cells by this antibody reportedly can be blocked by hamster anti-mouse CD49b antibody (clone HMα2). This antibody is routinely tested by flow cytometric analysis. Other applications were tested during antibody development only or reported in the literature. Detection of NK cells with monoclonal antibodies. Freshly isolated splenocytes from a C57BL/6 mouse were simultaneously incubated with PE mouse anti-mouse NK-1.1 antibody (NKR-P1B and NKR-P1C) (clone PK136) (MN 557391, both panels), and purified rat anti-mouse CD49b antibody (clone DX5) (right panel), followed by a FITC mouse anti-rat IgM antibody (clone G53-238) (Cat. No. 553887, both panels). Flow cytometry was performed on a BD FACScan™ instrument . Page 1 of 2553855 Rev. 11
