Chelating Chromogenic Substrates

Chelating Chromogenic Enzyme substrates offer a coloured endpoint when used in the presence of a metal ion. Enzyme substrates with the chromogens 8HQ, Alizarin, CHE and Brown all offer an insoluble endpoint, and are therefore best suited for use in solid media. Whereas DHN based substrates give a soluble endpoint thus ideally suited to applications in liquid media.
