Recombinant Human Tumor Necrosis Factor, His
TNF-α, TNF-alpha
Cachectin, Cachexin

Tumor necrosis factor (or TNF-α), also called cachectin, is produced by neutrophils, activated lymphocytes, macrophages, NK-cells, LAK-cells, astrocyte endothelial cells, smooth muscle cells and some transformed cells. TNF occurs as a secreted, soluble form and as a membrane-anchored form, both of which are biologically active. The naturally occurring form of TNF is glycosylated, but nonglycosylated recombinant TNF has comparable biological activity. The biologically active native form of TNF is reportedly a trimer. Human and murine TNF has approximately 79% homology at the amino acid level and there is cross-reactivity between the two species. Two types of receptors for TNF, p55 and p75, have been described and virtually all cell types studied show the presence of one or both of these receptor types.

TNF-α, His has an identical amino acid sequence to Human TNF-α, but with 6x-His at the N-terminus for protein purification (see Additional Information for sequence).
