The Glycerol GK test kit is a simple, reliable and accurate method for the measurement and analysis of glycerol in beverages, foodstuffs and other material. Based on use of ADP-glucokinase and increase in absorbance on conversion of NAD+ to NADH.
Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4oC.
Suitable for manual, auto-analyser and microplate formats.
UV-method for the determination of Glycerol in foodstuffs,
beverages and other materials
Principle:
(glycerokinase)
(1) Glycerol + ATP → L-glycerol-3-phosphate + ADP
(ADP-GK)
(2) ADP + D-glucose → G-6-P + AMP
(glucose-6-phosphate dehydrogenase)
(3) G-6-P + NAD+ → gluconate-6-phosphate + NADH + H+
Kit size: 70 assays (manual) / 700 (microplate)
/ 600 (auto-analyser)
Method: Spectrophotometric at 340 nm
Reaction time: ~ 7 min
Detection limit: 0.37 mg/L
Application examples:
Wine (and grape juice), beer, spirits, vinegar, marzipan, fruit juices,
soft drinks, toothpaste, honey, tobacco, paper (and cardboard),
cosmetics, pharmaceuticals, soap and other materials (e.g. biological
cultures, samples, etc.)
