Glutathione Xpure Agarose Resin consists of glutathione covalently bound to agarose beads. This resin has high binding affinity and specificity to the Glutathione S-transferase (GST) protein. GST-tagged proteins can be highly purified by batch or column purification (low flow rate) in a one step purification method. Bound GST-tagged proteins are easily eluted from the resin with buffers containing reduced glutathione
