Glutathione agarose prepared by linking the sulfur atom of glutathione to crosslinked beaded agarose can be used for purification of GST fusion proteins. Each milliliter of gel can bind approximately 5-6 mg of boivine-liver GST. Adding excess free glutathione liberates the GST fragment from the matrix which can then be regenerated by washing with a high-salt buffer.
