A rapid, novel High Performance Liquid Chromatography method for the purification of Glutathione S-transferase: An application to the human placental enzyme

A simple High Performance Liquid Chromatography procedure is detailed for the purification of Glutathione S-transferase. The human placental transferase was used to assess its potential. Unlike conventional methods of purification, the procedure is rapid and resolution of the various forms is achieved in less than 20 min. Since recovery is essentially complete, it is possible to isolate different minor forms. Three forms, one major and two minor, were separated. The major form represented about 97% of the total recovered activity and exhibited a specific activity of 254.94 [mu]moles/min/mg protein with a purification of 1342-fold. Electrophoresis of the major form revealed the presence of a single band, suggesting homogeneity.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25703/1/0000257.pd
