Recombinant Rat TNF Protein

Cat.No.: TNF-1071R
Product Overview: Recombinant mature form of rat TNFα (P16599) (Leu 80-Leu 235) was expressed and purified, with an initial Met at the N-terminus.
Source: E. coli
Species: Rat
Predicted N Terminal: Met
Form: Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
Bio-activity: Measured in a cytotoxicity assay using L929 mouse fibrosarcoma cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is typically 0.01-0.02 ng/mL.
Molecular Mass: The recombinant rat TNFα consisting of 157 amino acids and has a calculated molecular mass of 17.4 kDa. It migrates as an approximately 15 kDa band in SDS-PAGE under reducing conditions.
Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
Purity: >93 % as determined by SDS-PAGE.
Stability: Samples are stable for up to twelve months from date of receipt at -70ºC.
Storage: Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
