Muromonab Biosimilar, CD3 Mono

Muromonab Biosimilar uses the same protein sequences as the therapeutic antibody muromonab (OKT3). Muromonab (OKT-3) is a monoclonal anti-CD3 antibody used as immunosuppressive therapy in kidney, heart, and liver transplant patients. Murine monoclonal antibody specific to CD3 T-cell lymphocyte antigens. More specifically it is a purified murine (mouse) monoclonal antibody, directed against the CD3 (T3) receptor on the surface of human T-cells (T-lymphocytes) cultured using the murine ascites method. Muromonab is 93% monomeric immune globulin G type 2a (IgG2a). Muromonab binds to the T-cell surface glycoprotein CD3 epsilon chain. It appears to kill CD-3 positive cells by inducing Fc mediated apoptosis, antibody mediated cytotoxicity and complement-dependent cytotoxicity.
