Dilution Of Sample
The recommended dilution factor for different samples is as follows (for reference only):
| Sample type | Dilution factor |
|---|---|
| 10% Rat liver tissue homogenate | 3000-5000 |
| 10% Mouse muscle tissue homogenate | 10-20 |
The diluent is buffer solution A. For the dilution of other sample types, please do pretest to confirm the dilution factor.
Detection Principle
Glycogen produces glucose under the action of starch glycosidase, and glucose is catalyzed by glucose oxidase to produce hydrogen peroxide. In the presence of the peroxidase, hydrogen peroxide be oxidized to produce the fluorescence substrate. The fluorescence intensity at the excitation wavelength of 535 nm and emission wavelength of 587 nm is proportional to the glycogen content.

Technical Data:
Parameter:
Intra-assay Precision
Three rat liver samples were assayed in replicates of 20 to determine precision within an assay. (CV = Coefficient of Variation)
| Parameters | Sample 1 | Sample 2 | Sample 3 |
| Mean (μg/mL) | 0.15 | 1.00 | 2.50 |
| %CV | 4.0 | 3.2 | 3.0 |
Inter-assay Precision
Three rat liver samples were assayed 20 times in duplicate by three operators to determine precision between assays.
| Parameters | Sample 1 | Sample 2 | Sample 3 |
| Mean (μg/mL) | 0.15 | 1.00 | 2.50 |
| %CV | 7.3 | 6.2 | 6.3 |
Sensitivity
The analytical sensitivity of the assay is 0.06 μmol/L. This was determined by adding two standard deviations to the mean O.D. obtained when the zero standard was assayed 20 times, and calculating the corresponding concentration.
Standard Curve:
As the fluorescence value of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique or temperature effects), so the standard curve and data are provided as below for reference only:
| Concentration (μmol/L) | 0 | 0.5 | 1.0 | 1.5 | 2.0 | 2.5 | 3.0 | 4.0 |
| Fluorescence value | 1269 | 2695 | 3650 | 5304 | 6826 | 8119 | 9197 | 11360 |
| 1257 | 2599 | 3519 | 5209 | 6885 | 7861 | 9271 | 11325 | |
| Average fluorescence value | 1263 | 2647 | 3585 | 5257 | 6856 | 7990 | 9234 | 11343 |
| Absoluted fluorescence value | 0 | 1384 | 2322 | 3994 | 5593 | 6727 | 7971 | 10080 |
