Glutathione (γ-L-glutamyl-L-cysteinylglycine) is a tripeptide present in the body, and it is involved in antioxidation, drug metabolism, and other as enzyme substrate of glutathione peroxidase, glutathione S-transferase, and thiol transferase, etc. Glutathione is usually present as reduced form (GSH), but GSH is converted into its oxidized form (GSSG) by stimulation such as oxidative stress. Therefore, the ratio of GSH and GSSG has been noted as index of oxidative stress.
The GSSG/GSH Quantification kit contains Masking Reagent of GSH. The GSH can be deactivated in the sample by simply adding the Masking Reagent. Therefore, temp-only the GSSG is detected by measuring the absorption (λmax = 412 nm) of DTNB (5,5 Edithiobis (2-nitrobenzoic acid) using the enzymatic recycling system. Also, GSH can be determined the quantity by subtracting GSSG from the total amount of glutathione.
The kit is limited to quantifying GSH/GSSG concentration from 0.5 μmol/l to 50 μmol/l and GSSG concentration from 0.5 μmol/l to 25 μmol/l.
|Developer||Dojindo Molecular Technologies, Inc.|
Although conventional masking reagent, 2-Vinylpyridine(2-VP), interferes the reaction of GSSG measurement, Dojindo’s masking reagent does not interfere the reaction of GSSG measurement. Therefore, the exact ratio of GSSG and GSH is obtained with Dojindo GSSG/GSH detection Kit.
Measurement of GSSG with or without GSH masking reagent
Reducing agents such as ascorbic acid, β-mercaptoethanol, dithiothreitol (DTT) and cysteine, or thiol reactive compounds such as maleimide compounds, interfere with the glutathione assay. Therefore, SH compounds, reducing agents and SH reactive materials should be avoided during the sample preparation.
