MK-LACGAR Lactose/Galactose Assay Kit (Rapid) Kit 1 mL; galactose dehydrogenase (200 U/mL) / $509.60  
Introduction:

The Lactose/Galactose (Rapid) test kit is used for the rapid test of lactose, D-galactose and L-arabinose in food and plant products. Galactose dehydrogenase can be used the measurement and analysis of both D-galactose and L-arabinose. Suitable for the analysis of lactose in “low-lactose” or “lactose-free” samples which contain high levels of monosaccharides.

UV-method for the determination of Lactose and D-Galactose in 
foodstuffs, beverages and other materials

Principle:
                   (β-galactosidase)
(1) Lactose + H2O → β-D-galactose + D-glucose

            (galactose mutarotase)
(2) α-D-Galactose ↔ β-D-galactose

                    (β-galactose dehydrogenase)
(3) β-D-Galactose + NAD+ → D-galactonic acid + NADH + H+
 

Kit size:                            115 assays
Method:                            Spectrophotometric at 340 nm
Reaction time:                  ~ 15 min
Detection limit:                 2.96 mg/L (lactose)
Application examples:
Milk, dairy products (e.g. cream, milk / whey powder, cheese,
condensed milk and yogurt), foods containing milk (e.g. dietetic foods,
bakery products, baby food, chocolate, sweets and ice-cream), food
additives, feed, cosmetics, pharmaceuticals and other materials
(e.g. biological cultures, samples, etc.)
Method recognition:    
Methods based on this principle have been accepted by AOAC, NBN,
DIN, GOST and IDF
