Description
Principle of the Assay: TPX catalyzes H2O2 to oxidize dithiothreitol (DTT). The absorption wavelength of H2O2 is 240nm. TPX activity can be calculated by measuring the decrease rate of absorbance at 240nm and subtracting H2O2 catalyzed by catalase (CAT). Therefore, this kit can measure TPX and CAT activities of samples simultaneously
