Cynomolgus / Rhesus TNF-alpha 

分子别名（Synonym）:TNF 种属（Species）：Cynomolgus 表达系统（Expressed Host）：E. coli 制剂（Buffer）：Lyophilized from sterile 50 mM Tris, 50 mM NaCl, pH 8.0. 分子量（Molecule Mass）：The recombinant cynomolgus TNF consists of 158 amino acids and has a calculated molecular mass of 17.4 kDa. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)：Measured in a cytotoxicity assay using L-929 mouse fibrosarcoma cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is typically 50-300 pg/ml. 表达区间（Protein Construction）：A DNA sequence encoding the cynomolgus TNF [(Identical to the rhesus TNF (NP_001040614.1)] (Val77-Leu233) was expressed and purified with an initial Met. 存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution. 运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
