Serum & Plasma:

α-GST is expressed in hepatocytes and its increase in blood is a sensitive indicator of acute hepatic injury. Increased αGST has been demonstrated to be indicative of hepatotoxicity, allograft rejection, viral hepatitis.

Intended use

α-GST is a member of the GST superfamily of small cytosolic proteins primarily involved in cellular detoxification reactions. α-GST is approximately 51kDa and can comprise upto 2 % of the cytosolic soluble protein content. As a result of its constitutive nature, α-GST is immediately released into the urine upon lysis of epithelial cells of the proximal tubule.

The α-GST EIA provides a method for the quantitative determination of alpha glutathione S-transferase
(α-GST) in human serum and plasma. The α-GST EIA can also be used for the determination of αGST in human urine, to assess kidney injury.
