| Bioactivity | Mapatumumab (HGS-ETR1) is a fully human IgG1 agonistic monoclonal antibody that targets tumor necrosis factor-related apoptosis-inducing ligand receptor 1 (TRAIL-R1). Mapatumumab can be used for the research of cancer[1]. |
| Invitro | Mapatumumab (0.01-100 μg/mL; 4 h) shows no growth inhibition to Pediatric Preclinical Testing Program (PPTP) cell lines[1].Mapatumumab (1-100 ng/mL; 24 h) shows significant potentiation of cytotoxicity and synergy when combined with (epirubicin) EPI for bladder cancer cells[2].Mapatumumab (100 ng/mL; 12 h) induces significant cell apoptosis of T24, 253J and J82 cells with the combination of EPI (1 µg/mL)[2].Mapatumumab (100 ng/mL; 6-24 h) significantly activates caspase-8, -9 and -3 with the combination of EPI (1 µg/mL)[2]. |
| In Vivo | Mapatumumab (10 mg/kg; i.p. for three times) controls tumor growth when combined with irradiation[3]. Animal Model: |
