CD81 (TAPA-1, Target of anti-Proliferative Antibody-1)

CD 81, a 26kD cell surface antigen also known as TAPA-1 and a member of the tetraspanin family. CD81 is widely expressed on human leukocytes and appears to be involved in a variety of cellular leukocytes and appears to be involved in a variety of cellular processes, including adhesion, activation, proliferation and differentiation. The antibody is a potent CD81 reagent, induces homotypic adhesion and has powerful anti proliferative effects.
