Recombinant Human Tumor Necrosis Factor - alpha 10ug
Descirption - Tumor Necrosis Factor-α Human Recombinant produced
in E.Coli is a single, non-glycosylated, polypeptide chain containing
158 amino acids and having a molecular mass of 17483.77 Dalton.
The TNF-alpha is purified by standard chromatographic techniques.
Appearance - Sterile Filtered White lyophilized (freeze-dried) powder
Formulation - 1mg of TNF-alpha Human contain 20mM PBS, pH-7.2, and 10mM NaCl
Solubility - It is recommended to reconstitute the lyophilized Tumor
Necrosis Factor-alpha in sterile 18M-cm H2O not less than 100µg/ml,
which can then be further diluted to other aqueous solutions.
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).
Purity - Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE Please prevent freeze-thaw cycles
