Frequently Asked Questions

Frequently Asked Questions are available for this Product.

Application

May be used at 5-10 mM to elute glutathione S-transferase (GST) from glutathione agarose.

L-Glutathione (GSH) reduced has been used in the elution buffer to elute GST (glutathione S-transferase)-fused proteins using glutathione-agarose beads. It has been used to prepare a standard curve for GSH analyses.

Biochem/physiol Actions

Endogenous antioxidant that plays a major role in reducing reactive oxygen species formed during cellular metabolism and the respiratory burst. Glutathione-S-transferase catalyzes the formation of glutathione thioethers with xenobiotics, leukotrienes, and other molecules that have an electrophilic center. Glutathione also forms disulfide bonds with cysteine residues in proteins. Via these mechanisms, it can have the paradoxical effect of reducing the efficacy of anti-cancer agents.

Reduced L-glutathione (GSH) is a thiol compound and is associated with catabolism and transportation. Plasma GSH levels are associated with Parkinson′s diseases, Alzheimer′s, diabetes, macular degeneration, and HIV (human immunodeficiency virus) disease.
