Abstract

PURPOSE: To increase the accuracy of measurement at low concentration solution for quantitative analysis of enzyme activity, by using the merdola blue as electron carrier.
CONSTITUTION: In the buffer liquid tank 1, for example, NAD in 1μM, lactic acid of 50μM, merdola blue of 10μM, and phosphric acid buffer solution pH8.0 of 0.1M, are put in. Further, the sample LDH(enzyme for dehydrogen lactic acid) is injected from the intake 2, and the buffer solution and sample are fed to the electrode 3 with the pump 4. To the electrode 3 as active electrode and to contrast electrode, platinum and saturated caromel electrode are used respectively. In this case, corresponding to LDH activity, NAD becomes NADH. The NADH is changed into NAD by using the oxygen type merdola blue, and the reduction type merdola blue changed corresponding to NADH is electrochemically oxided by using the electrode 3, and the current of oxidation is measured via the current voltage converter 6 and the voltmeter 7 to quantitatively analyze the lactic acid dehydrogen enzyme.
