Description

Sarilumab (anti-IL-6Rα) is a fully human anti-IL-6Rα mAb that binds membrane-bound and soluble human IL-6Rα with high affinity, MW: 144.13 KD.

Features

Human IgG1

Targets

IL-6R (human) ^[1]	IL-6R (monkey) ^[1]
61.9 pM(Kd)	71.9 pM(Kd)

In Vitro
In vitro	Sarilumab can reverse IL-6 enhanced colony formation in HCC cells under sorafenib or regorafenib treatment.^[1]
Cell Research:	Cells were treated with drugs for 36 h. The soluble form of IL-6Rα in cell culture supernatants was measured with a human IL-6Rα ELISA kit according to the manufacturer’s instructions. Plates were measured on a microplate reader at a wavelength of 450 nm.

Frequently Asked Questions

Question 1:
How to store the antibody?

Answer:
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.
