Application Notes
In WB a specific band is observed ~160 kDa and an apparant non-specific band is observed ~56 kDa. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended. In ICC/IF, membrane staining was observed in Raw 264.7 cells. This antibody does not appear to work in human samples with WB. The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

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).
