生物活性:
Tocilizumab (Anti-Human IL6R, Humanized Antibody) is an anti-human interleukin-6 receptor (IL-6R) neutralizing antibody, prevents binding of IL-6 to the IL-6R, thereby inhibiting both classic and trans-signaling. Tocilizumab (Anti-Human IL6R, Humanized Antibody) can be used for the treatment of rheumatoid arthritis. Tocilizumab is remarkablely effective for the study of severe COVID-19 (coronavirus disease).
体内研究:
Tocilizumab (抗人 IL6R,人源化抗体) (静脉注射;1.0 mg/100 μL;每周两次,三周) 减少注射了 tocilizumab 的小鼠大脑中每个转移灶的体积。 Tocilizumab (抗人 IL6R,人源化抗体) (腹膜内注射;100 μg/mL,每 48 小时一次;20 天) 抑制 OSCC 进展并抑制肿瘤血管生成。 br>Animal Model:A brain metastasis model of lung tumor cells by inoculating HARA-B cells in nude mice
Dosage:1.0 mg/100 μL
Administration:Intravenous injection; 1.0 mg/100 μL; twice a week, three weeks

体外研究:
Tocilizumab (抗人 IL6R,人源化抗体) (1-100 ng/mL;24 小时、48 小时) 以剂量依赖性方式抑制细胞增殖 (生长速率),HACM 的生长速率几乎完全降低 100 ng/mL tocilizumab。 Tocilizumab (抗人 IL6R,人源化抗体) (0.001-10,000 μg/mL;2 天) 抑制 Ba/F3-gp130-IL-6R 细胞用 hIL-6 刺激增殖,IC50 为 13.5 ng/mL。 Tocilizumab (抗人 IL6R,人源化抗体) (1 μM;6 小时) 在体外降低 STAT3 的磷酸化,与体内 SAS 细胞一致。 Tocilizumab (抗人 IL6R,人源化抗体) (1-5 μM;24 小时) 用无血清培养基显著降低SAS细胞中VEGF mRNA的表达。
