A simple procedure for the preparation of lo-500 mg of the Escherichia coli elongation Tu-Ts complex is described. The protocol is based on the separate purification and quantitation of EF-Tu-GDP and EF-Ts, followed by mixing of equimolar amounts of each protein and removal of the displaced GDP by d

โฆ Synopsis
A bulk purification procedure has been designed to maximize the yield of Escherichia coli elongation factor, Ts, with a minimum of effort and time. The enzyme purification is achieved by DEAE-Sepharose and elongation factor Tu-affinity chromatographies. The typical yield is 150 mg/kg of E. coli (B) cells.
