TNFA Rat, His Active

Source: Escherichia Coli.Sterile Filtered colorless liquid.Tumor necrosis factor is a cytokine involved in systemic inflammation and is a member of a group of cytokines that all stimulate the acute phase reaction. TNF is mainly secreted by macrophages. TNF causes apoptotic cell death, cellular proliferation, differentiation, inflammation, tumorigenesis and viral replication, TNF is also involved in lipid metabolism, and coagulation. TNF's primary role is in the regulation of immune cells.Dysregulation and, in particular, overproduction of TNF have been implicated in a variety of human diseases- autoimmune diseases, insulin resistance, and cancer.TNFA Rat Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 181 amino acids (80-235 a.a) and having a molecular mass of 19.9kDa.TNFA Rat is expressed with an 25 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
