Recombinant TNF alpha comprises a 157 amino acid fragment (77-233) corresponding to the mature soluble TNF alpha chain protein. TNF alpha is expressed in E. coli with an amino-terminal hexahistidine tag.

TNF alpha is a potent pleiotrophic cytokine, produced by white blood cells, endothelium and several other normal and tumor cells in response to a wide variety of stimuli. TNF alpha is involved in the pathophysiological processes of several chronic and acute diseases including the induction of apoptosis and up regulation of inflammation.
