The Ha31/8 antibody reacts with the 180- kDa integrin α1 chain (CD49a), which is a transmembrane glycoprotein that non-covalently associates with the integrin β1 subunit (CD29) to form the α1β1 (complex known as VLA-1). VLA-1 has been reported to be expressed on activated T cells, monocytes, smooth muscle cells, and endothelial cells. It is a receptor for collagen and laminin. The Ha31/8 monoclonal antibody is specific for both rat1 and mouse CD49a. It has been reported that Ha31/8 antibody can block VLA-1-mediated binding of rat cells to collagen.
