Monoclonal human IgG1 antibody against human CD20
Anti-hCD20-Of-hIgG1 features a human IgG1 constant region (Fc) and the variable region of Ofatumumab which targets the human CD20 antigen found on the surface of normal and malignant B lymphocytes.
Ofatumumab is a fully human type I (first generation) monoclonal antibody that mediates B cell destruction through complement-dependent cytotoxicity (CDC) and antibody-dependent cellular cytotoxicity (ADCC). Ofatumumab has been approved by the FDA for the treatment of chronic lymphocytic leukaemia (CLL) [1-3].
InvivoGen’s Anti-hCD20-Of-hIgG1 is generated by recombinant DNA technology, produced in CHO cells, and purified by affinity chromatography (protein G).
More isotypes of this antibody are available and can be used for comparison of biological activities such as ADCC (see below).
InvivoGen also provides type I anti-hCD20 mAbs featuring the variable regions of Rituximab or Obinutuzumab, with either native or engineered Fc region.
