TNF-alpha Recombinant Protein

The ED50as determined by the cytolysis of murine L929 cells in the presence of Actinomyocin D is = 0.05 ng/mL, corresponding to a specific activity of = 2 x 107 units/mg.

The lyophilized TNF-alpha recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted TNF-alpha is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing TNF-alpha recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
