Biological Activity
The ED50 as determined by the cytolysis of murine L929 cells in the presence of Actinomycin D is < 0.05ng/ml, corresponding to a Specific Activity of 20MIU/mg.

Description
Tumor Necrosis Factor-a Variant Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 151 amino acids and having a molecular mass of 16598 Dalton.
The TNF-alpha Variant is purified by standard chromatographic techniques.

Formulation
The protein was lyophilized after extensive dialysis against 0.5x PBS pH -7.

Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.

Purity
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized Tumor Necrosis Factor-alpha Variant in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source
Escherichia Coli.

Stability
Lyophilized Tumor Necrosis Factor-a Variant although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution TNF-a Variant should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
