A stabilized indicator powder for use in assays to detect the presence of peroxidase or other peroxidatively active substances, wherein the indicator is stabilized by being combined with a water soluble polymer. As a dry powder, the indicator retains its reactivity for at least several months. The powder readily dissolves in an aqueous medium and as a solution retains its reactivity for a period of weeks, even in the presence of peroxide. |
