          Product Specific Information

          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.

          Target Information

          TNF beta, a member of the tumor necrosis factor family, is a cytokine produced by lymphocytes. The protein is highly inducible, secreted, and forms heterotrimers with lymphotoxin-beta which anchor lymphotoxin-alpha to the cell surface. This protein also mediates a large variety of inflammatory, immunostimulatory, and antiviral responses, is involved in the formation of secondary lymphoid organs during development and plays a role in apoptosis. Genetic variations in this gene are associated with susceptibility to leprosy type 4 and psoriatic arthritis.
