Detection of Mouse CD11b/Integrin alpha M by Western Blot. Western blot shows lysates of RAW 264.7 mouse monocyte/macrophage cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Mouse CD11b/Integrin alpha M Monoclonal Antibody (Catalog # MAB11241) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for CD11b/Integrin alpha M at approximately 160 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: CD11b/Integrin alpha M
The Integrin family proteins are heterodimeric transmembrane receptors composed of an alpha and a beta subunit. The Integrin alpha M subunit, also known as MAC-1 alpha subunit or CD11b, combines with the Integrin beta 2 subunit (CD18) to form the non-covalent heterodimer Integrin alpha M/ beta 2, also known as MAC-1 and complement receptor type 3 (CR3). Integrin alpha M/ beta 2 is expressed on granulocytes, macrophages, dendritic cells and natural killer cells. Upon activation, alpha M/ beta 2 can bind several ligands (including ICAM-1, fibrinogen, and the C3 complement fragment, C3bi) to mediate phagocyte adhesion, migration and ingestion of complement-opsonized particles (1,2).
