Title: Purification and activation of proteins from insoluble inclusion bodies
IPC: C12P21/02
Filed: 1986-08-18
Abstract: Purification and solubilization of a protein produced in a transformant microorganism as insoluble, biologically inactive inclusion bodies can be effected by extracting the inclusion bodies into a buffered solution of sodium dodecyl sulfate (SDS) to solubilize the protein; treating the SDS-protein solution with urea; removing the SDS and purifying the protein by chromatography on an anion-exchange column; and dialyzing the solution obtained from the anion-exchange column to remove urea, thereby allowing the protein to fold into its native conformation.
