| Description: |
Human Tumor necrosis factor (TNF-
alpha), also known as Cachectin, is a cytokine composed
of 157 amino acid residues, having a molecular weight of
17 kDa (monomer). There is 79% homology between human
and murine TNF- alpha, including conserved cysteine
residues which form an intrachain disulfide bridge.
Biological effects of this cytokine include antitumor
activity in vivo and in vitro, activation of
polymorphonuclear leukocytes, antiviral activity, and
the induction of the release if Interleukin-1 or colony
stimulating factors from a variety of sources.
Human TNF- alpha (Cachectin) is produced in
genetically engineered yeast, and purified by sequential
chromatography.
