Catalase (CAT) Activity Fluorometric Assay Kit

Cat.No.:E-BC-F006
Detection instrument: Fluorescence microplate reader (Ex/Em=535 nm/587 nm)

Detection method: Fluorescence method

Detection principle

Catalase can decompose H2O2 to generate H2O and O2, the residual H2O2 in the detection system react with the fluorescent substance, and the content of residual H2O2 is proportional to the fluorescence intensity at the excitation wavelength of 535 nm and emission wavelength of 587 nm, the catalase activity is inversely proportional to the fluorescence intensity.

Dilution of sample

It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the pre-experiment and the detection range (0.01-6.51 U/L).

The recommended dilution factor for different samples is as follows (for reference only):

Sample type	Dilution factor
Mouse serum	60-80
Mouse plasma	60-80
Rat serum	70-80
Human saliva	30-50
Rat urine	30-50
10% Mouse liver tissue homogenate	2500-3000
10% Mouse lung tissue homogenate	200-400
