Sample Type: Whole blood, serum, plasma, erythrocytes, urine, cell lysates, and tissue samples Target: Glutathione and Oxidized Glutathione Method of Analysis: Absorbance Plate Reader Intended Use: Quantitatively measure glutathione (GSH) and oxidized glutathione (GSSG) present in a variety of samples, including whole blood, serum, plasma, erythrocytes, urine, cell lysates, and tissue samples. Analyze the absorbance colorimetric signal by spectrophotometer. Test Principle: Glutathione, gamma-L-glutamyl-L-cysteinyl-glycine or GSH, is the most abundant non-protein thiol in cells. GSH is involved in the regulation of a number of essential biochemical processes within the cell. Primarily recognized as a key intracellular source of reducing power for combating the toxic accumulation of free radical byproducts, GSH is also involved with detoxifying and removal of exo/endogenous toxins and alkylating agents. In its role as a cell signaling agent, GSH is involved in DNA synthesis and cell prol
