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

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.

  1. How does the storage temperature relate to shipping conditions?

    The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.

  2. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  3. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  4. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.

  6. What are the GSH levels in human tissues?

    The GSH levels in human tissues normally range from 0.1 to 10 mM, most concentrated in the liver (up to 10 mM) and in the spleen, kidney, lens, erythrocytes, and leukocytes. Bremer HJ. Duran M, Kamerling JP, et al. Glutathione. In: Bremer HJ,DuranM, Kamerling JP, et al, eds. Distubance of Amino Acid Metabolism: Clinical Chemistry and Diagnosis. Baltimore-Munich: Urban and Schwarzenber; 1981:80-82.

  7. What is the GSH level in plasma?

    It is in the micromolar range (approximately 4.5 mM). Chawla RK, Lewis FW, Kutner MH, et al. Plasma cysteine, cysteine, and glutathione in cirrhosis. Gastroenterology, 87, 770-776 (1984).
