Tocilizumab
Based on 47 publication(s) in Google Scholar
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).

In Vitro
Tocilizumab (Anti-Human IL6R, Humanized Antibody) (1-100 ng/mL; 24 hours, 48 hours) inhibits the cell proliferation (growth rate) in a dose-dependent manner, growth rate by HACM is reduced almost completely by 100 ng/mL tocilizumab[2]. Tocilizumab (Anti-Human IL6R, Humanized Antibody) (0.001-10,000 μg/ml; 2 days) inhibits Ba/F3-gp130-IL-6R cell proliferation stimulated with hIL-6 with an IC50 of 13.5 ng/ml[1]. Tocilizumab (Anti-Human IL6R, Humanized Antibody) (1 μM; 6 hours) reduces the phosphorylation of STAT3 in vitro consistent with in vivo SAS cells[3]. Tocilizumab (Anti-Human IL6R, Humanized Antibody) (1-5 μM; 24 hours) significantly reduces VEGF mRNA expression in SAS cells with serum-free medium[3].
