Abstract:
1. A method for measuring amylase activity in saliva, comprising contacting a reagent for measuring amylase activity to saliva containing amylase, and measuring quantitatively with a color discriminating sensor a labeling substance which is liberated from a substrate, wherein said reagent comprises at least a modified oligosaccharide which is a substrate carried on a support; wherein said modified oligosaccharide is an oligosaccharide selected from G2, G3, G4, G5, G6, and G7, and the reducing end of the oligosaccharide is modified by a chromogen; wherein a light-emitting body provides a light source directed at the substrate; and said measuring quantitatively comprises measuring an intensity of light reflected from the substrate or transmitted through the substrate and outputting an electric signal corresponding to the intensity of the reflected light or transmitted light.
