3 Principle of Measurement
Law for the IFCC recommended method. Its principle of the method reaction equation is as follows.
L- aspartic acid α- ketoglutarate →
AST L- glutamate oxaloacetate
Oxaloacetate NADH H →
MDH
NAD-malic acid L-
In the coupling reaction with the oxidation rate of NADH activity was directly proportional specimens, NADH at 340nm wavelength has a specific absorption
Income can be monitored NADH absorbance to calculate the rate of decline of vitality AST.
AST catalytic L- aspartate aminotransferase and malate dehydrogenase (MDH) catalyzed coupling reactions, so that the oxidation of NADH
NAD. NADH has a specific absorption peak at 340nm at a rate proportional to the activity which is oxidized and serum AST in 340nm
NADH absorbance was measured at the rate of descent can be measured AST activity (U/L).
4 Requirements
4.1 Appearance
Compatible with the manufacturer's normal appearance requirements.
4.2 PACKING
Loading amount of the liquid reagent to be less than the labeled amount.
4.3 reagent blank
4.3.1 Reagent blank absorbance
Reagent blank absorbance of not less than 1.0 (wavelength 340nm, optical path 1cm).
