Detection of CD11b/Integrin alpha M in Human Spleen. CD11b/Integrin alpha M was detected in formalin fixed paraffin embedded sections of human spleen using Mouse Anti-Human CD11b/Integrin alpha M Monoclonal Antibody (Catalog # MAB16992) at 5 µg/ml for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with Hematoxylin (blue). Specific staining was localized to cell surface and cytoplasm of lymphocytes.

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.
