Method for carrying out enzyme assays

摘要

Peroxidatively active enzyme assays have a variety of clinical and industrial applications. Such assays are based on color development resulting from the addition of the appropriate substrate to the enzyme-containing medium. The stability of the said substrate and the extent of appearance of color are two serious limitations in enzyme assays. A method is disclosed herein for carrying out peroxidatively active enzyme assays when the enzyme is in free solution or in cell-bound form. Stable chemical compositions are also disclosed for use as substrates for carrying out such method.
