Product Summary for CD11b Antibody (OX-42) [Alexa Fluor® 594]

Immunogen

Mouse Monoclonal CD11b Antibody (OX-42) was made from rat peritoneal macrophages.

Specificity

NB100-65284 recognizes the rat equivalent of human CD11b, the receptor for the iC3b component of complement. The antigen is expressed on most macrophages, including resident and activated peritoneal macrophages and Kupffer cells and around 35% of alveolar macrophages. This CD11b antibody also labels dendritic cells, granulocytes and microglial cells in the brain. Clone MRC OX-42 has been reported as being suitable for use on paraffin-embedded material following PLP fixation (periodate-lysine-paraformaldehyde). Functionally, clone OX-42 inhibits complement mediated rosettes.

Background: CD11b/Integrin alpha M

CD11b (integrin alpha M subunit) is a type I transmembrane glycoprotein. 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). The CD11b/CD18 (Mac-1) heterodimer has a theoretical molecular weight of 127kDa but is often observed near 170kDa due to post translational modifications. Integrins are transmembrane proteins that mediate interactions between adhesion molecules on adjacent cells and/or the extracellular matrix. Integrins have diverse roles in several biological processes, including cell migration during development, wound healing, cell differentiation, and apoptosis. The particular integrin CD11b is known as a pro-inflammatory molecule given its ability to promote phagocyte cytotoxic functions while enhancing several effector molecules such as FcGR, uPAR, and CD14 (1). In macrophages, CpG-DNA stimulates lysosomal degradation and vacuolar acidification, subsequently promoting CD11b release via TLR9 (2). During an acute infection, high CD11b/Mac-1 expression on antigen-specific CD8 (+) T cells can signify recent activation of the immune system, whereas naive T cells and virus-specific memory CD8 (+) T cells express little or no Mac-1 when exposed to a virus (3). Variations at the ITGAM gene, which encodes for the CD11b chain of the Mac-1 integrin, is one of the main genetic risk factors involved in systemic lupus erythematosus /SLE disorder (4).
