APC Anti-Human CD11c (3.9)

TDS | SDS The 3.9 antibody reacts with human CD11c, also known as integrin αalpha X. This 150 kDa cell surface glycoprotein is part of a family of integrin αreceptors that mediate adhesion between ≥ ≥ ≥ cells (cell-cell) and components of the extracellular matrix, e.g. fibrinogen (cell-matrix). In addition, integrin αs are active signaling receptors which recruit leukocytes to inflammatory sites and promote cell activation. Complete, functional integrin αreceptors consist of distinct combinations of integrin αchains which are differentially expressed. integrin αalpha X (CD11c) assembles with integrin αbeta-2 (CD18) into a receptor known as CR4 which can bind and induce signaling through ICAMs and VCAM-1 on endothelial cells and can also facilitate removal of iC3b bearing foreign cells. The 3.9 antibody is widely used as a marker for CD11c expression on dendritic cells (DC), often in parallel with markers for CD11b, for identification of developmental stages and mature subsets of thi
