CheKine™ Micro Glutathione Peroxidase (GSH-Px) Activity Assay Kit

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.

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.

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.

• 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) .
