The Lactulose Assay Kit is suitable for the specific, rapid and sensitive measurement and analysis of lactulose in milk and milk-based samples. Reagents included in this kit may also be prepared for use in the procedure described by ISO Method 11285:2004.

UV-method for the determination of Lactulose in milk and foodstuffs containing dairy products Principle: (β-galactosidase) (1) Lactulose + H₂O → D-galactose + D-fructose (glucose oxidase + catalase + H₂O₂) (2) D-Glucose + H₂O + O₂ → D-gluconic acid + H₂O₂ (hexokinase) (3) D-Fructose + ATP → F-6-P + ADP (phosphoglucose isomerase) (4) F-6-P → G-6-P (glucose-6-phosphate dehydrogenase) (5) G-6-P + NADP⁺ → gluconate-6-phosphate + NADPH + H⁺ (gluconate-6-phosphate dehydrogenase) (6) Gluconate-6-phosphate + NADP⁺ → ribulose-5-phosphate + NADPH + CO₂ + H⁺

Kit size: 50 assaysMethod: Spectrophotometric at 340 nmReaction time: ~ 120 minDetection limit: 4.8 mg/LApplication examples:Milk, dairy products and foods containing milkMethod recognition: Novel method
