TNF-a (Tumor necrosis factor), being an endogenous pyrogen, is able to induce fever, apoptotic cell death, inflammation and to inhibit tumorigenesis. As reported, TNFa could inhibit the proliferation and induce apoptosis of A549 cells, and the concentration of IL-1β and IL-8 in cell supernatant will increase after stimulation. Therefore, A549 cells were incubated in DMEM with TNFa (1 ng/ml, 10 ng/ml, 100 ng/ml, 1000 ng/ml) for 8h, IL-1β and IL-8 were detected in the cell supernatant by ELISA. After incubation with TNF-a for 8h, IL-1β significantly increased in the cell supernatant.
Lyophilized from 20 mM Tris (pH 8.0) with 150 mM NaCl, 1 mM EDTA, 1 mM DTT, 0.01% SKL, 5% Trehalose, Proclin300. Reconstitute with 20 mM Tris and 150 mM NaCl (pH 8.0) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
For short-term storage (1-2 weeks), store at 4ºC. For long-term storage, store at -20ºC or below. After reconstitution, keep as concentrated solution.Avoid freeze-thaw cycles.
