InactiveCN1693881ALow costSimplified inosine coupling enzymatic reaction systemMaterial analysis by observing effect on chemical indicatorMicrobiological testing/measurementHydrogenPeroxidase
Heinz(1980) makes use of the adenosine ammonia-deleted enzyme to change adenosine into hypo-yellow and gains H2O2 through the reaction of the enzyme1 and enzyme2. With the effect of the catalase and aldehyde hydrogen-deleted enzyme, Heinz measures the velocity of increase of the degree of NADPH absorbing light at 334 nms to gain adenosine ammonia-deleted enzyme's activity. The method's weakness is high cost of the reagents. The invention introduces Trinder's reaction to combine aniline type hydrogen and 4- to from a coloured product with the effect of H2O2 gained by the reaction of enzyme3 in the situation of the catalase. By watching the quantity of this coloured product, people can determine the adenosine ammonia-deleted enzyme's activity. The invention simplifies the Heinz's reaction system and lowers the cost. The invention uses the aniline compound ADOS, ADPS, ALPS, TODB, TOOS and TOPS as hydrogen provider for Trinder's reaction and increases the reaction's agility. The invention also involves a reagent box used for implementing the method mentioned above.
