CD120b, otherwise known as sTNF receptor type II (sTNFR1I), is a member of the tumor necrosis factor receptor (TNFR) superfamily, produced by proteolytic cleavage of the membrane form by the metalloprotease TACE. CD120b plays a key role in regulating the inflammatory response, acting as a receptor for both tumor necrosis factor alpha (TNF-alpha) and TNF-beta, and is also involved in programmed cell death and anti-viral activity. sTNFR1I acts as an inhibitor of TNF-alpha induced responses, by acting as a decoy receptor.
Source:E. coli
Applications:Suitable for use in Functional Assays. Other applications not tested.
Biological Activity:Determined by its inhibitory effect of the TNF-alpha mediated cytotoxicity in murine L-929 cells. The ED50 for this effect in the presence of 0.25ng/ml of recombinant human TNF-alpha is 0.125ug/ml.
Storage and Stability:Lyophilized and reconstituted products may be stored at -20°C. Stable for 6 months after receipt at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
