Glycerol GK Assay Kit

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

(1) Glycerol + ATP → L-glycerol-3-phosphate + ADP

(2) ADP + D-glucose → G-6-P + AMP

       (glucose-6-phosphate dehydrogenase)
(3) G-6-P + NAD+ → 6-phosphogluconate  + NADH + H+

Kit size:    70 assays (manual) / 700 (microplate)
                                          / 600 (auto-analyser)

The number of manual tests per kit can be doubled if all volumes are halved. 
This can be readily accommodated using the MegaQuantTM 
Spectrophotometer (D-MQWAVE).

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.)
