Why Use the HT Glutathione Peroxidase Assay Kit?

Tetrameric Glutathione Peroxidase catalyzes the reduction of H2O2 to water, and organic peroxides to the corresponding stable alcohols, by using glutathione as a source of reducing equivalents. It requires selenium as a cofactor and contains a selenocysteine amino acid residue in the active site of each monomer that participates in the actual mechanism of the enzyme. Glutathione Reductase (GR), provided with each kit, then reduces the oxidized glutathione to complete the cycle. The oxidation of NADPH to NADP+ is accompanied by a decrease in absorbance at 340 nm. The rate of decrease in the absorbance at 340 nm is directly proportional to the Glutathione Peroxidase activity in the sample.

  1. Is this kit capable of measuring serum/plasma samples? 

    • This kit may be used to measure Glutathione Peroxidase activity in serum or plasma samples following the procedures in the kit insert.

  2. What is the dynamic range of this kit?

    • The dynamic range of the Glutathione Peroxidase kit is dependent on source of the sample. The minimum level of sensitivity is twice that of the background slope of the change of absorbance at 340 nm versus time (in the absence of GP).

      Some tissues may generate very high levels of GP and the sample will have to be serially diluted to give a good linear decrease in absorbance at 340 nm over a 10 minute period.
