Oxidation Reaction

Product Description

SAT-3 is a stable, highly water-soluble o-Tolidine analog.

It is easily oxidized by peroxidase and hydrogen peroxide into a green dye at pH 4-6.

While TMBZ requires an organic solvent or detergent to solubilize, SAT-3 can be solubilized with just buffer solution.

The SAT-3 solution can be stored at room temperature with protection from light.

The maximum wavelength of the dye is 675 nm.

Using the Ames test, Nno mutagenicity of SAT-3 was detected. using the Ames test.
