Overview
Introduction
Sugar is one of the most important sources of energy in biology. It is regulated by various factors within an organism. Glucose converges to a stable ratio of α-form and β-form in solutions.
Assay principle
α-D-Glucose is converted to β-D-Glucose by mutarotase. Hydrogen peroxide, which is produced by a reaction between β-D-Glucose and glucose oxidase(GOD), promotes oxidative condensation of phenol with 4-aminoantipyrine quantitatively. LabAssay™ Glucose is a kit used for the quantitative determination of glucose concentrations in samples by measuring absorbance of a red color which is generated by the oxidative condensation reaction.
Performance
| Sample | Serum, plasma(Mouse, Rat, Human) |
|---|---|
| Standard curve range | 50 ~ 500 mg/dL (mg/100 mL) |
| Measurement time | approx. 10 min. |
| Amount of sample | 2 μL |
| Measurement wavelength | 505 nm(main), 600 nm(sub) |
Standard Curve
Procedure
Perform the assay in the wells according to the following table scheme.
| Test | Standard | Blank | |
|---|---|---|---|
| Chromogen reagent | 300 μL | 300 μL | 300 μL |
| Sample | 2 μL | 2 μL | - *1 |
| Mix well and incubate at 37 ℃ for 5 min. Measure the absorbance at 505 nm*2 of the test sample and standard solution with the blank solution as the control. |
|||
*1: The addition of water is omitted because the absorbance difference in the presence of the addition of 2 μL of water does not exhibit any practical use.
*2: Use 505 nm (Main) and 600 nm (Sub) for two wavelengths.
