Peroxidase (POD) was used to catalyze the decomposition of hydrogen peroxide into water and oxygen, and oxygen oxidized pyrogallic acid to form yellow products. The enzyme activity was obtained by measuring the absorbance (OD value) change at 420 nm.
Applications
It is suitable for the detection of POD activity in plant tissues, but not in serum and plasma.
Procedure
1. Prepare standard samples and experimental samples. 2. Add reaction reagents in order for reaction. 3. Measure the absorbance of each tube. 4. Make the mark curve and calculate the result.
