Background Information
TNF, as also known as TNF-alpha, or cachectin, is a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily. It is expressed as a 26 kDa membrane bound protein and is then cleaved by TNF-alpha converting enzyme (TACE) to release the soluble 17 kDa monomer, which forms homotrimers in circulation. It is produced chiefly by activated macrophages, although it can be produced by many other cell types such as CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils, and neurons. 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, INS resistance, and cancer.

Reviews
What customers say
Users report mixed results for this antibody in Western Blot and Immunofluorescence applications. One reviewer found it performed well at 1:1000 dilution in U2OS cells, detecting TNF-alpha clearly on the upper membrane region. Another reviewer experienced very weak signal at 1:250 dilution in HaCaT cells. Overall, performance appears to be cell-type and dilution-dependent, with strong results in some contexts but weak signal in others.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
