Mouse anti Rat CD49d monoclonal antibody, clone MRalpha4-1 recognizes rat CD49d, otherwise known as integrin alpha 4 chain/VLA-4, a ~150 kDa single pass type-1 transmembrane glycoprotein and member of the integrin alpha chain family, which acts as a receptor for fibronectin and CD106 (VCAM-1).

CD49d is expressed broadly on T and B lymphocytes, monocytes, thymocytes, mast cells and dendritic cells and is involved in cell-cell interactions, mononuclear cell trafficking to sites of endothelial inflammation, and the adhesion of cells to the extracellular matrix.

Clone MRalpha4-1 inhibits the in vitro and in vivo functions of CD49d (Yasuda et al. 1995). Studies have shown that in rat Peyer's patches, clone MRalpha4-1 inhibits the rolling and adherence of lymphocytes to postcapillary venules (PCV), and significantly inhibits the transendothelial migration of T lymphocytes (Tsuzuki et al. 1996).
