【Abstract】 Biologically active human Iysozyme from an engineered bacterium E.coli was obtained by isolation and solubilization of inclusion bodies as well as renaturation of solubilized polypeptides. The inclusion bodies could also be obtained after the treatment of cell with acetone,instead of sonication.The additions of PEG, glutathione glycerol,or sodium sulfite and sodium thiosulfate in the renaturation solution, can increase yield of renatured active human lysozyme.更多还原
