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).

Description

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[1]. Tocilizumab is remarkablely effective for the study of severe COVID-19 (coronavirus disease)[4].

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
