Product overview
GSH Assay Kit (Colorimetric) (ab239727) provides a simple in vitro assay for detecting reduced GSH levels in apoptosis and other pathological processes. The Kit is based on an enzymatic cycling method in the presence of GSH and a chromophore. The reduction of the chromophore produces a stable product, which can be followed kinetically at 450 nm. Therefore, its absorbance is directly proportional to the amount of GSH in the sample.
The assay is simple, reproducible and can specifically detect as low as 50 pmol/well of reduced form of Glutathione (GSH) in a 100 µl reaction.
This assay specifically detects reduced glutathione. Oxidized GSSG is not detected.

Notes
This product is manufactured by BioVision, an Abcam company and was previously called K464 Reduced Glutathione (GSH) Assay Kit (Colorimetric). K464-100 is the same size as the 100 test size of ab239727.

Relevance
Glutathione is a small peptide composed of three amino acids: cysteine, glutamic acid, and glycine and is present in tissues in concentrations as high as one millimolar. It contains an unusual peptide linkage between the amine group of cysteine and the carboxyl group of the glutamate side chain. Glutathione is involved in detoxification, it binds to toxins, such as heavy metals, solvents, and pesticides, and transforms them into a form that can be excreted in urine or bile. It is also an important antioxidant, helping to maintain the -SH groups of proteins in their reduced form. Chronic functional glutathione deficiency is associated with glucose 6-phosphate dehydrogenase deficiency, immune disorders, an increased incidence of malignancies, and in the case of HIV disease, probably accelerated pathogenesis of the disease. Acute manifestations of functional glutathione deficiency can be seen in those who have taken an overdosage of acetaminophen (paracetamol). This results in depletion of glutathione in the hepatocytes, leading to liver failure and death. -
