TNF-α occurs as a secreted, soluble form and as a membrane-anchored form, both of which are biologically active. The naturally-occurring form of TNF-α is glycosylated, but non-glycosylated recombinant TNF-α has comparable biological activity. The biologically active native form of TNF-α is reportedly a trimer. Two types of receptors for TNF-α have been described and virtually all cell types studied show the presence of one or both of these receptor types.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cspan class=\"bhp-cat-pill\"\u003eE. coli Expression\u003c\/span\u003e\n\u003cp\u003eRecombinant Tumor Necrosis Factor-alpha Rat protein is produced using a validated E. coli expression system and supplied as lyophilized powder for long-term stability.
