Tumor Necrosis Factor α (TNF-α) is an inflammatory cytokine secreted by macrophages, monocytes, neutrophils, T cells, and Natural Killer (NK) cells following stimulation by bacterial lipopolysaccharide (LPS). TNF-α signal activation occurs through two receptors, TNFR1 and TNFR2. TNFR1 is expressed on most cell types, unlike TNFR2, which is expressed mainly on immune cells. TNF-α functions to stimulate phagocytosis in macrophages, chemoattract neutrophils, increase insulin resistance, and induce fever.Activity Assay
Rat TNF-α (Animal-Free) is fully biologically active when compared to standard. The activity is determined by the cytolysis of mouse L929 cells in the presence of Actinomycin D and it is typically less than 50 pg/ml. This corresponds to an expected specific activity of 2.0 x 107 units/mg.AA Sequence
