Abstract
Disclosed herein are a method and a reagent test kit, both using an improved substrate to measure the amylase content of a sample. The substrate used is a glycoside consisting of a defined polysaccharide glycosyl residue and a substituted aromatic radical attached to the terminal unit of the glycoside. When detached from the polysaccharide, the aglycone exhibits a different spectral absorbance than the substrate.
