Reduced L-Glutathione is the best way for well performed protein elution from GST tag affinity beads during a protein purification process. It is recommended to be used as a component in the elution buffer of all our GST Affinity tag protein purification products. L-Glutathione (reduced) is the major low molecular weight thiol compound of living plants or animal cells. Blood, brain concentrations and mouse tissue concentrations are reported in the literature as well as a review on reduced glutathione.
