Human acute monocytic leukaemia cells.
Recognizes the human CD35 cell surface glycoprotein, a molecule which exists in four allotypic forms (A, B, C, D) of 190kD, 220kD, 160kD and 250kD respectively. The molecule is expressed by granulocytes, monocytes, B cells and some T cells. Functionally CD35 acts as a receptor for the C3b component of complement.
