The L17F12 monoclonal antibody binds to human CD5, a 67-kDa single chain type I glycoprotein in the scavenger receptor family (1)(2).  CD5, also known as Leu-1, Ly-1 or T1, is expressed on thymocytes, T cells and subsets of B cells. CD5 binds to its ligand on B cells, CD72 (LYB-2), to play a role in T-B cell interaction and to modulate the intensity of antigen receptor signal transduction (3). The antibody was conjugated to a fluorophore and purified by affinity chromatography.
