Abstract
A composition of a polysaccharide with a detectable material appended thereto and a 1,3-dione having a methylene group between the two carbonyls of the 1,3-dione, which methylene group has at least one ionizable hydrogen, provides accurate results in assays of hydrolyzing enzymes such as amylase. The composition can be incorporated in the reagent zone of a dry test element having a reagent zone and a registration zone.
