Description
Specification
| Product name | Micro Glutathione Peroxidase (GSH-Px) Activity Assay Kit |
| Applications notes | GSH-Px catalyzes H2O2 to oxidize GSH to produce GSSG; glutathione reductase (GR) catalyzes NADPH to reduce GSSG to regenerate GSH, while NADPH oxidizes to produce NADP+; NADPH has a characteristic absorption peak at 340 nm, while NADP+ does not; NADPH dehydrogenation rate is determined by measuring the decrease rate of absorbance at 340 nm to calculate GSH-Px activity. |
Product Properties
| Kit components | • Assay Buffer • Substrate • GR • H2O2 |
| Features & Benefits | • Determination of GSH-Px activity in serum, plasma, plant tissue/cell lysates and other biological fluids. |
| Usage notes | • 96 Well Clear Flat Bottom UV-Transparent Microplate is needed. • The whole processes need to be carried out on ice, and the enzyme activity should be determined on the same day, to avoid repeated freeze-thaw of the homogenate solution. • Prepare mixed reagents for use, and place on ice. • The measuring process should be operated quickly and only 1 ~ 2 blank well should be needed. • The reaction temperature has influence on the result. Keep the temperature at 25°C (for general species) or 37°C (for mammals). |
| Storage instructions | Storage at -20°C and Keep from light immediately upon receipt. Kit has a storage time of 12 months from receipt. Refer to list of materials supplied for storage conditions of individual components. |
| Shipping | Gel pack with blue ice. |

Additional Information
| Background | GSH-Px is one of the main enzymes that catalyze the oxidation of reduced glutathione (GSH) in the glutathione redox cycle. GSH-Px not only specifically catalyzes the reaction between reduced glutathione and ROS to form oxidized glutathione GSSG, thereby protecting the biofilm from ROS damage and maintaining the normal function of cells; it also protects the liver and improves the body immunity, antagonizing the harmful effects of harmful metal ions on the body and increasing the body’s ability to resist radiation. |
