Product Name Tumor Necrosis Factor-Alpha Rabbit Recombinant
Synonyms Tumor necrosis factor, Cachectin, TNF-alpha, Tumor necrosis factor ligand superfamily member 2, TNF-a, TNF, TNFA, TNFSF2. 
Description Tumor Necrosis Factor-a Rabbit Recombinant consists of three identical polypeptide chains of 158 amino acids combined to form a compact, bell-shaped homotrimer. TNF-alpha was produced in E.Coli is a non-glycosylated, polypeptide chain having a molecular mass of 17.4 kDa for the individual subunit. The TNF-alpha is purified by standard chromatographic techniques.
Uniprot Accesion Number P04924
Amino Acid SequenceThe sequence of the first five N-terminal amino acids was determined and was found to be Met-Ser-Ala-Ser-Arg.
Source Escherichia Coli.
Physical Appearance and Stability Lyophilized Tumor Necrosis Factor-a although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TNF-a should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Formulation and Purity TNF-alpha Rabbit was lyophilized after extensive dialysis against 20mM PB, pH7.4, 300mM NaCl. Greater than 95% as determined by
Solubility It is recommended to reconstitute the lyophilized Tumor Necrosis Factor-alpha in sterile 18MO-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity The ED50 as determined by the cytolysis of murine L929 cells in the presence of Actinomycin D is less than 0.03ng/ml, corresponding to a Specific Activity of 30,000,000 IU/mg.
Shipping Format and Condition Lyophilized powder at room temperature.
