Dilution Of Sample
The recommended dilution factor for different samples is as follows (for reference only):
| Sample type | Dilution factor |
|---|---|
| 10% Porcine heart tissue homogenate | 3-6 |
| 10% Porcine liver tissue homogenate | 8-10 |
| 1×10^6 CHO cells | 1-2 |
| 1×10^6 293T cells | 1-2 |
| Human serum | 100-120 |
| Mouse serum | 100-120 |
The diluent is extraction solution. For the dilution of other sample types, please do pretest to confirm the dilution factor.
Detection Principle
Triglyceride is converted by enzyme to produce hydrolytic products, which is catalyzed by enzymes to produce fluorescent substances. The content of triglyceride in samples can be calculate by measuring the fluorescence value.

Technical Data:
Parameter:
Intra-assay Precision
Three human serum 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 (μmol/L) | 2.50 | 15.00 | 25.00 |
| %CV | 4.2 | 3.8 | 3.7 |
Inter-assay Precision
Three human serum samples were assayed 20 times in duplicate by three operators to determine precision between assays
| Parameters | Sample 1 | Sample 2 | Sample 3 |
| Mean (μmol/L) | 2.50 | 15.00 | 25.00 |
| %CV | 10.0 | 8.9 | 8.4 |
Recovery
Take three samples of high concentration, middle concentration and low concentration to test the samples of each concentration for 6 times parallelly to get the average recovery rate of 105%.
| Standard 1 | Standard 2 | Standard 3 | |
| Expected Conc.(μmol/L) | 7 | 15 | 22 |
| Observed Conc. (μmol/L) | 7.5 | 15.8 | 22.7 |
| Recovery rate (%) | 107 | 105 | 103 |
Sensitivity
The analytical sensitivity of the assay is 0.8 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 | 6 | 12 | 15 | 18 | 21 | 24 | 30 |
| Fluorescence value | 1364 | 2032 | 3049 | 3402 | 4057 | 4330 | 4874 | 5703 |
| 1267 | 1975 | 3280 | 3320 | 4382 | 4698 | 4724 | 5951 | |
| Average fluorescence value | 1316 | 2003 | 3164 | 3361 | 4220 | 4514 | 4799 | 5827 |
| Absoluted fluorescence value | 0 | 687 | 1849 | 2045 | 2904 | 3198 | 3483 | 4511 |
