RTNFB20 contains 171 amino acid residues.
Purity: >98% pure by SDS-PAGE and N-terminal sequence analysis.
Activity: The ED50 is determined to be less than 0.05 ng/mL in the cytolysis assay of mouse L929 cells.
Use: TNFb exerts activity in the range of 0.1 to 10 ng/mL for most in vitro applications.
Reconstitution and Dilution: Reconstitute in distilled water to a concentration of 100 µg/mL. After reconstitution, dilute cytokine in a neutral buffer containing carrier protein such as 5-10% FBS or 1-4% high purity BSA (fatty acid free fraction V).
Lyophilized product is stable until expiration if stored desiccated below 0°C. Cytokines diluted as indicated above should be divided into aliquots and stored at -70°C. Recombinant proteins should be stored at concentrations >500 ng/mL to reduce loss of activity.
This gene encodes a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily. This cytokine is mainly secreted by macrophages. It can bind to, and thus functions through its receptors TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. This cytokine is involved in the regulation of a wide spectrum of biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation. This cytokine has been implicated in a variety of diseases, including autoimmune diseases, insulin resistance, and cancer. Knockout studies in mice also suggested the neuroprotective function of this cytokine.
