Recombinant Human Tumor Necrosis Factor

Cat. No. : TNF-194H
Product Overview : Recombinant human TNF-α was expressed inE.coliand purified by using conventional chromatography techniques. Additional amino acid, methionine, was attached at N-terminus of the protein. MW=17.5kDa (158 aa).
Description : Tumor necrosis factor alpha (TNF-α), also called cachectin, consists of 157 amino acids. TNF-α is a 17.5kD factor produced by neutrophils, CD4+ T cells, macrophage, NK cells, LAK cells, astrocytes endothelial cells, and smooth muscle cells. TNF-α is cytolytic and plays an important role in immune regulation including hemorrhagic tumor necrosis/cytotoxicity and inflammation, and in regulation of antiviral and immune proliferative and activation responses. The active form of this protein is a trimer.
Source : Escherichia Coli.
Purity : > 95% by SDS–PAGE.
Concentration : 1mg/ml (determined by Bradford assay).
Form : Liquid. In PBS buffer (pH7.4).
Endotoxin Level : < 1.0EU per 1 μg of protein (determined by LAL method).
Storage : Can be stored at +4°C short term (1-2 weeks). For long term storage, aliquot and store at -20°C or -70°C. Avoid repeated freezing and thawing cycles.
