| Purification | Protein A/G purified from cell culture supernatant. |
| Biological activity | DS-5573a (1 ug/mL) binds to the IgC1 and IgC2 domains of human B7-H3 expressed in transfected CHO-K1 cells [1]. The K d value of DS-5573a binding to recombinant human 4IgB7-H3 is 1.8 nM, and the K d value of its binding to recombinant human 2IgB7-H3 is 11 nM [1]. DS-5573a (0.01-1000 ng/mL; 4 h) exerts potent, B7-H3-dependent antibody-dependent cell-mediated cytotoxicity against NCI-H322, MDA-MB-231 and COLO205 cells via human peripheral blood mononuclear cells (PBMC), while exhibits only minimal activity against B7-H3-negative CCRF-CEM cells [1]. DS-5573a (1-10000 ng/mL; 3 h) exerts B7-H3-dependent antibody-dependent cellular phagocytosis (ADCP) activity against NCI-H322, MDA-MB-231 and COLO205 cells via human monocyte-derived macrophages, but shows no activity against B7-H3-negative CCRF-CEM cells [1]. Cell Cytotoxicity Assay [1] Cell Line: NCI-H322, MDA-MB-231, and COLO205 cells Concentration: 0.01, 0.1, 1, 10, 100, 1000 ng/mL Incubation Time: 4 h Result: Exerted potent, B7-H3-dependent ADCC activity against NCI-H322, MDA-MB-231, and COLO205 cells via human PBMCs. DS-5573a (0.003-3 mg/kg; i.p.; once a week; 5 weeks) exhibits dose-dependent, statistically significant antitumor activity against MDA-MB-231 breast adenocarcinoma in female SCID mice, with significant efficacy observed at doses as low as 0.03 mg/kg and maximal activity at 0.3 mg/kg and 3 mg/kg [1]. |
