背景介绍 B-cell maturation antigen (BCMA), also known as tumor necrosis factor receptor superfamily member 17 (TNFRSF17), is a protein encoded by the TNFRSF17 gene. TNFRSF17 is a cell surface receptor of the TNF receptor superfamily that recognizes B-cell activating factor (BAFF). BCMA is preferentially expressed in mature B lymphocytes and also on Multiple Myeloma (MM) cells. Upregulations of BCMA also correlates with disease burden and pro prognosis in multiple myeloma. This bispecific antibody binds to BCMA on cancer cells and CD3 on T cells simultaneously, thus bringing T lymphocytes closer to the cancer cells. The binding event potentiates unstimulated T cells and induces direct cytotoxicity against BCMA+ cancer cells. 产品介绍 Anti-BCMA-Anti-CD3-Avi-His-Tag is a purified recombinant human bispecific antibody with T cell Engager. This bispecific antibody has been tested for specific activity in both ELISA binding assay to BCMA-biotin and functional reporter assay using NFAT-luc reporter Jurkat cell line (BPS Bioscience #60621) in the presence of BCMA-CHO cells (BPS Bioscience #79500-H).
