      Detection principle

      Glutathione peroxidase (GSH-Px) can promote the reaction of hydrogen peroxide (H2O2) and reduced glutathione to produce H2O and oxidized glutathione (GSSG). The activity of glutathione peroxidase can be expressed by the rate of enzymatic reaction. The activity of glutathione can be calculated by measuring the consumption of reduced glutathione. Hydrogen peroxide (H2O2) and reduced glutathione can react without catalysis of GSH-Px, so the portion of GSH reduction by non-enzymatic reaction should be subtracted. GSH can react with dinitrobenzoic acid to produce 5-thio-dinitrobenzoic acid anion, which showed a stable yellow color. Measure the absorbance at 412nm, and calculate the amount of GSH.

      Dilution of sample

      The optimal sampling volume are different for different species, also are different for different sample type. It is recommended to take 2~3 samples to do a pre-experiment, diluting a series of diluent and determine the dilution factor when the inhibition ratio is 20%~60% (the optimal inhibition ratio is the range of 45%~55%.) before formal experiment.

      Note: The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4).

      Asked: I confused about the blank tube. If I have double beam spektro, what solution do i use for zeroing? And what blank for the standard & sample ?

      Asked: We don\'t have 412 nm of colorimetric spectro filter in my lab, we only have the 415 nm. And so, is it ok if we use 415nm? would it effect the accuracy of the measurement significantly? Could give me the contract of distributor in Thailand. Thank you.
