Mouse Monoclonal Antibody to CD11B (L1)

Integrin αM, also designated complement component receptor~3 α, CD11b (p170), macrophage antigen a polypeptide, cell surface glycoprotein Mac~1 a subunit, MAC1A, MO1A and ITGAM) is a cell adhesion molecule that acts as a receptor for cell surface ligands such as intracellular adhesion molecules (ICAMs) or soluble ligands. Integrins are heterodimeric proteins that contain an a chain and b chain. Integrin αM combines with the Integrin β2 to form a leukocyte~specific integrin referred to as macrophage receptor 1 (Mac~1), or inactivated~C3b (iC3b) receptor 3 (CR3). Integrin αM/β2 is important in the adherence of neutrophils and monocytes to stimulated endothelium, and also in the phagocytosis of complement coated particles.
