| Message | Product Description
REAGEN™ Glucose Assay Kit is a cuvette-based enzymatic assay for the determination of Glucose across a variety of food samples. The kit uses a spectrophotometric, kinetic assay to detect the enzymatic degradation of Glucose directly from food samples.
The unique features of the kit are:
High sensitivity and low detection limit (0.8 ppm)
High reproducibility
A rapid (30 minute), robust enzyme-based assay
Procedure Overview
REAGEN™ Glucose Assay Kit uses a coupled enzymatic reaction to detect glucose and/or fructose in food samples: glucose is detected by phosphorylation with hexokinase to make glucose-6-phosphate (G-6-P). This compound is then used as a substrate by the enzyme glucose-6-phosphate dehydrogenase to convert NADP+ to NADPH. This conversion, measured at 340 nm, is proportional to the level of glucose in the sample.
The absorbance of each sample at 340 nm is measured using a spectrophotometer. The concentration of glucose in each sample is then directly determined from the change in absorbance at 340 nm within 30 minutes.
Kit Contents, Storage and Shelf Life
REAGEN™ Glucose Assay Kit has the capacity for 48 determinations or 24 determinations in duplicate. Store the kit at 4°C. The shelf life of the kit is 12 months, after receipt, when the kit is properly stored.

Warnings and Precautions
Do not use the kit past the expiration date.
Try to maintain a laboratory temperature of 20°–25°C (68°–77°F). Avoid running assays under or near air vents, as this may cause excessive cooling, heating and/or evaporation. Also, do not run assays in direct sunlight, as this may cause excessive heat and evaporation. Cold bench tops should be avoided by placing several layers of paper towel or some other insulate material under the assay plates during incubation.
Make sure you are using only distilled or deionized water since water quality is very important.
When pipetting samples or reagents into an empty microtiter plate, place the pipette tips in the lower corner of the well, making contact with the plastic.
