Biological Activity

Description Tocilizumab (anti-IL-6R) is a humanized monoclonal antibody that binds to the interleukin-6 receptor, MW: 148 KD.
IL-6R [1]
In vitro

After adding tocilizumab at different concentrations into HMO6 and CHME5 cells stimulated by F3-CM or with IL6, the expression levels of anti-inflammatory M2 markers (CD206 and Arg1) are decreased, as well as the levels of both phosphorylated JAK2 and STAT3.[1]

In vivo

Tocilizumab can block JAK2/STAT3 activation and impede brain metastasis (BM) of A549-F3 cells in vivo.[1]

Protocol (from reference)

Cell Research:
  • HMO6 and CHME5 cells with control media or F3-CM alone or F3-CM were treated with Tocilizumab (2.5 μg/ml for 24 h) or with IL6 (200 ng/ml for 24 h) alone or IL6-supplemented with Tocilizumab. Western blot analysis of p-JAK2, JAK2, p-STAT3, and STAT3 in HMO6 and CHME5 cells were conducted.

Animal Research:
  • Animal Models: Nude mice of brain metastasis models
    Dosages: 5 mg/kg
    Administration: i.p.

Frequently Asked Questions

Question 1:
How to store the antibody?

Store the undiluted solution at 4 °C in the dark. Freezing antibodies can result in a loss of activity caused by the freezing/thawing process. Diluting antibodies to working concentrations and storing at 4°C for more than a day should be avoided. Additionally, make sure to keep the antibody sterile. Under these storage conditions, your antibodies should remain active for up to one year and oftentimes longer.
