HER2 (trastuzumab) antibody - Human IgA2
Monoclonal human IgA2 antibody against HER2
Anti-HER2-Tra-hIgA2 features the constant region of the human IgA2 isotype and the variable region of trastuzumab. Trastuzumab is a humanized IgG1 monoclonal antibody that targets the HER2 receptor (human epidermal growth factor receptor 2 also known as HER2/neu) that is found on the cell membrane of epithelial cells. HER2 plays an important role in normal cell growth and differentiation . However, in certain types of cancers, particularly in breast and ovarian cancers, HER2 is over-expressed and causes uncontrollable cell proliferation. Binding of trastuzumab to HER2 results in cell death through different mechanisms including antibody-dependent cell-mediated cytotoxicity and phagocytosis [2, 3]. Trastuzumab has been approved by the FDA for the treatment of breast cancer.
Anti-HER2-Tra-hIgA2 was generated by recombinant DNA technology. It has been produced in CHO cells and purified by affinity chromatography with peptide M.
