Purity
> 97% as determined by (a) RP-HPLC.(b) SDS-PAGE.
Activity
The Specific Activity ≥ 5.0 107 IU/mg as determined by the cytolysis of murine L929 cells in the presence of Actinomycin D.
Storage Buffer
Protein(1 mg/mL) was lyophilized from a solution containing 20 mM PB, pH 7.2, 100 mM NaCl . Reconstitute the lyophilized powder in ddH2O to 100 ug/mL.
Storage Instruction
Lyophilized protein at room temperature for 3 weeks, should be stored at -20°C. Protein aliquots at 4°C for 2-7 days and should be stored at -20°C to -80°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid repeated freeze/thaw cycles. -

HyperlinkGene Summary
This gene encodes a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily. This cytokine is mainly secreted by macrophages. It can bind to, and thus functions through its receptors TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. This cytokine is involved in the regulation of a wide spectrum of biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation. This cytokine has been implicated in a variety of diseases, including autoimmune diseases, insulin resistance, and cancer. Knockout studies in mice also suggested the neuroprotective function of this cytokine. [provided by RefSeq
