Anti-hCD20-hIgG4 features the constant region of the human IgG4 isotype and the variable region of rituximab.
Rituximab is a mouse/human chimeric monoclonal antibody that targets the CD20 antigen found on the surface of malignant and normal B lymphocytes.
Binding of rituximab to CD20 results in cell destruction through different mechanisms including direct signaling of apoptosis, complement activation and cell-mediated cytotoxicity.
Rituximab has been approved by the FDA for the treatment of various lymphoid malignancies, including B-cell non-Hodgkin's lymphoma and B-cell chronic lymphocytic leukaemia.
Anti-hCD20-hIgG4 was generated by recombinant DNA technology. It has been produced in CHO cells and purified by affinity chromatography with protein G.
