APC Mouse Anti-Human CD11b Antibody (HI11b)

CD11b, also known as integrin alpha M, is a transmembrane glycoprotein that pairs with CD18 to form the Mac-1 integrin, also referred to as complement receptor type 3 (CR3). It is predominantly expressed on the surface of myeloid cells, including monocytes, neutrophils, macrophages, and microglia. CD11b plays a crucial role in mediating cell adhesion and migration, facilitating the interaction between immune cells and their targets. It is involved in phagocytosis, the process by which cells engulf and eliminate foreign particles or debris. Additionally, CD11b acts as a receptor for complement C3bi, mediating complement-coated particle uptake, and it binds to various ligands such as intercellular adhesion molecules (ICAMs) and fibrinogen, contributing to cell-mediated cytotoxicity, chemotaxis, and immune cell activation.
