[Expression in Escherichia coli of DNA coding for human tumor necrosis factor].
The variants of expression in Escherichia coli of artificial DNA coding for human tumor necrosis factor, an important immune modulator with selective cytotoxic action on a number of transformed cell lines have been described. The DNA was placed under control of either phage M13 promoter of gene for main coat protein or tandem of pair of E. coli tryptophane promoters. It has been shown that E. coli cells harbouring plasmids described with artificial TNF gene provide good level of protein biosynthesis. The protein has been purified by anion exchange chromatography near to homogeneity and used for preparation of monoclonals. As result three hybridomas effectively produced high affinity monoclonal anti-TNF antibodies have been obtained and characterized.
