Technical Data
CD11B (Integrin alpha-M, CD11 Antigen-like Family Member B, CR-3 alpha Chain, Cell Surface Glycoprotein MAC-1 Subunit alpha, Leukocyte Adhesion Receptor MO1, Neutrophil Adherence Receptor, ITGAM, CR3A)
The CBRM1/5 antibody reacts with an activated form of human CD11b, a 165-170kD type I transmembrane glycoprotein also known as aM integrin, Mac-1, CR3, and C3biR. CD11b non-covalently associates with integrin b2 (CD18) and is expressed on granulocytes, monocytes/macrophages dendritic cells, NK cells, and subsets of T and B cells. CD11b/CD18 is critical for the transendothelial migration of monocytes and neutrophils, as well as adhesion, phagocytosis and neutrophil activation. This antibody does not recognize "non-activated" CD11b. The epitope recognized by CBRM1/5 is contained in the I domain of the alpha chain. The CBRM1/5 antibody blocks cell adhesion to fibrinogen and ICAM-1.
