Principle] Hydrogen peroxide is an important intermediate metabolite in the analysis of trace components in living organisms, food quality control, environmental substances and other tests.

DA-64 and DA-67 are water-soluble oxidizers that can detect hydrogen peroxide with high sensitivity in the presence of peroxidase.

DA-64 and DA-67 are water-soluble oxidizing reagents that can detect hydrogen peroxide with high sensitivity in the presence of peroxidase. Conventional water-soluble oxidative reagents for hydrogen peroxide have a high sensitivity for the detection of hydrogen peroxide in the presence of peroxidase.

The conventional water-soluble hydrogen peroxide coloring reagents are difficult to handle due to the low molecular absorbance coefficient of the chromore and its microsolubility despite its high sensitivity.

DA-64 and DA-67 are the first reagents that are compatible with water solubility and high sensitivity. In the past, in order to pursue high sensitivity, it was necessary to use luminescent and fluorescent reagents.

In the past, it was necessary to use luminescent and fluorescent reagents in order to achieve high sensitivity. Now, a group of test objects detected by a special specialized detector is also detected by using the DA-64 and DA-67.

DA-64 and DA-67 can be used to obtain results with a simple colorimeter. The advantage of this product is that it is more difficult to be affected by coexisting substances than the DA-64.
