Recombinant Human Tumor necrosis factor protein (TNF) (Active)

Fully biologically active when compared to standard. The ED50 as determined by a cytotoxicity assay using murine L929 cells is less than 0.01 ng, ml, corresponding to a specific activity of 1.0 108 IU, mg in the presence of actinomycin D.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
