IPC: G01N27/48
Filed: 1983-06-10
Abstract: PURPOSE:To make it possible to simultaneously measure the density of glucose and activity of amylase by such an arrangement wherein a hydrogen peroxide detection type polarograph is equipped with one kind of enzyme electrode which is equipped with an enzyme membrane in which two kinds of enzyme are fixed, and the speed of change of a current of the electrode is measured. CONSTITUTION:As a specimen including amylase and glucose is injected into a buffer solution including polysaccharide, an enzyme electrode composed of a membrane which selectively transmits hydrogen peroxide, wherein alpha-glucosidase and glucose oxidase are simultaneously fixed and a hydrogen peroxide electrode produces hydrogen peroxide, and due to the produced hydrogen peroxide, the primary increase A in electrode current which is proportional to the density of glucose takes place. After a period of 15-30sec, the secondary increase B in electrode current which is proportional to the activity of amylase takes place. Since the speed of the primary and secondary increase in electrode current is proportional to the density of glucose and the activity of amylase in each of (1)-(6) specimens respectively, it becomes possible to simultaneously measure the activity of glucose and amylase by one kind of enzyme electrode.
