7.背景Background:
Tumor Necrosis Factor-alpha(TNF-alpha) is a potent lymphoid factor that exerts cytotoxic effects on a wide range of tumor cells and certain other target cells. Human TNF-alpha is a 17.4 kDa protein containing 157 amino acid residues. 
8保存和稳定性Storage&Stability:
Avoid repeated freeze and thaw cycle.Store at 2-8℃ for delivery and store at -20 or -70℃ for future use. The loss rate of the target protein which describes the stability was determined by accelerated thermal degradation test.That is to incubate the protein at 37℃ for 48h and no obvious degradation and precipitation were observed.The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
