ABSTRACT:
A method for the determination of amylase activity and a useful highly stable color reagent aqueous solution therefore are disclosed. The solution comprises, as a color reagent, an aromatic nitro containing compound such as 3,5-dinitrosalicyic acid, a color stabilizing chelating compound such as ethylenediaminetetraacetic acid, and a hydroxide base. Eliminating the necessity for centrifuging prior to the determination of amylase activity can be achieved by including potassium hydroxide for at least a part of the base in the solution.
