More Details
Glucose (C6H12O6) is a key diagnostic parameter for many metabolic disorders. Increased glucose levels have been associated with diabetes mellitus, hyperactivity of thyroid, pituitary and adrenal glands. Decreased levels are found in insulin secreting tumors, myxedema, hypopituitarism and hypoadrenalism. Simple, direct and high-throughput assays for measuring glucose concentrations find wide applications in research and drug discovery. BioAssay Systems glucose assay kit uses a single Working Reagent that combines the glucose oxidase reaction and color reaction in one step. The color intensity of the reaction product at 570nm or fluorescence intensity at λex/em = 530/585nm is directly proportional to glucose concentration in the sample.What are the differences between the three EnzyChrom Glucose assay kits?
EBGL – best at detecting low levels of glucose (as low as 5 µM)
EGL2 – best at measuring high levels of glucose using a low wavelength filter (340 nm)
EGL3 – best at measuring high levels of glucose using a high wavelength filter (565 nm)
Which of the three EnzyChrom Glucose assay kits can be used with urine, saliva, or serum samples?
EBGL – Not recommended for urine, saliva, or serum samples
EGL2 – Compatible with urine and serum samples, not recommended for saliva samples
EGL3 – Recommended for urine, saliva, and serum samples
*Sample blanks are to be used when testing urine samples with EGL2 or EGL3
How specific is this assay (EBGL)?
Glucose oxidase is fairly specific for D-glucose and does not react with fructose, galactose, or xylose. It does react with the following sugars: 2-deoxy-D-glucose (11% relative activity compared to D-glucose), 4-o-methyl-D-glucose (7%) and mannose (3%).
Can this kit be used to measure glucose concentrations in cells?
Glucose is converted into glucose-6-phosphate within the cell, which may not react with our assay. We have not tested it, but if the concentration of free glucose in the cell is within the detection range (1 to 30 μM for fluorimetric assays) of the assay it could still work.
