Product Name Tumor Necrosis Factor-alpha Human Recombinant, HEK
Synonyms TNF-alpha, Tumor necrosis factor ligand superfamily member 2, TNF-a, Cachectin, DIF, TNFA, TNFSF2.
Description TNF-a Human Recombinant produced in HEK cells is a glycosylated non-disulfide linked homotrimer, containing 157 and having total Mw of 17kDa.The TNF-a is purified by proprietary chromatographic techniques.
Uniprot Accesion Number P01375
Source HEK.
Physical Appearance and Stability Lyophilized TNF-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 The TNF-a protein was lyophilized from 1mg/ml in 1xPBS. Greater than 95% as obsereved by SDS-PAGE.
Solubility It is recommended to reconstitute the lyophilized TNF-a in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity The specific activity was determined by the dose-dependent cytotoxity of the TNF alpha sensitive cell line L-929 in the presence of Actinomycin D and is typically 0.05-0.5ng/ml.
Shipping Format and Condition Lyophilized powder at room temperature.
