D-果糖/D-葡萄糖[MegaQuant法]检测试剂盒

The D-Fructose and D-Glucose MegaQuant™ Format test kit is suitable for the measurement and analysis of D-fructose and D-glucose in grapes, grape juice and wine using the MegaQuant™ colorimeter (measurement at 505 nm).

Simple colourimetric method for the determination of
D-Fructose and D-Glucose in foodstuffs, beverages and
other materials

Principle:
(hexokinase)
(1) D-Glucose + ATP → G-6-P + ADP

(hexokinase)
(2) D-Fructose + ATP → F-6-P + ADP

(phosphoglucose isomerase)
(3) F-6-P ↔ G-6-P

(glucose-6-phosphate dehydrogenase)
(4) G-6-P + NADP⁺ → gluconate-6-phosphate + NADPH + H⁺

(diaphorase)
(5) INT + NADPH + H⁺ → NADP⁺ + INT-formazan

Kit size:  60 assays
