trastuzumab emtansine (TAB-H70)

Anti-Human ERBB2 Therapeutic Antibody (trastuzumab emtansine) TAB-H70 1mg Please Inquiry


  • Product Overview
  • Recombinant Humanized (from mouse) antibody to Human ERBB2. Trastuzumab emtansine (ado-trastuzumab emtansine, trade name trastuzumab emtansine) is an antibody-drug conjugate consisting of the monoclonal antibody trastuzumab (trastuzumab) linked to the cytotoxic agent mertansine (DM1). Trastuzumab alone stops growth of cancer cells by binding to the HER2/neu receptor, whereas mertansine enters cells and destroys them by binding to tubulin. Because the monoclonal antibody targets HER2, and HER2 is only over-expressed in cancer cells, the conjugate delivers the toxin specifically to tumor cells. The conjugate is abbreviated T-DM1.

  • Antigen Description
  • Receptor tyrosine-protein kinase erbB-2, also known as CD340 (cluster of differentiation 340), proto-oncogene Neu, Erbb2 (rodent), or ERBB2 (human) is a protein that in humans is encoded by the ERBB2 gene, which is also frequently called HER2 (from human epidermal growth factor receptor 2) or HER2/neu.
  • Function
  • ATP binding; ErbB-3 class receptor binding; Hsp90 protein binding; RNA polymerase I core binding; epidermal growth factor-activated receptor activity; glycoprotein binding; contributes_to growth factor binding; identical protein binding; nucleotide bindin
