分子量：Approximately 16.9kDa,a single non-glycosylated polypeptide chain containing 151 amino acids.Compared with the wild-type,rHuTNF-α Variant has an amino acid sequence(a.a.)deletion from a.a.1-7,and the following a.a.substitutes Arg8,Lys9,Arg10 an

概述
The clinical use of the potent antitumor activity of TNF-α has been limited by the proinflammatory side effects including fever,dose-limiting hypotension,hepatotoxicity,intravascular thrombosis,and hemorrhage.Designing clinically applicable TNF-αmutants with low systemic toxicity has been an intense pharmacological interest.Human TNF-α,which binds to the murine TNF-R55 but not to the murine TNF-R75,exhibits retained antitumor activity and reduced systemic toxicity in mice compared with murine TNF-α,which binds to both murine TNF receptors.Based on these results,many TNF-αmutants that selectively bind to TNF-R55 have been designed.These mutants displayed cytotoxic activities on tumor cell lines in vitro,and exhibited lower systemic toxicity in vivo.
