Dilution of Sample
It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the pre-experiment.
The recommended dilution factor for different samples is as follows (for reference only):
| Sample type | Dilution factor |
| 20% Epipremnum aureum tissue homogenate | 1 |
| 20% Celery tissue homogenate | 1 |
| 20% Cilantro tissue homogenate | 1 |
| 20% Rat liver tissue homogenate | 1 |
| 20% Rat kidney tissue homogenate | 1 |
| 20% Corn tissue homogenate | 1 |
Note: The diluent is reagent 1.
Detection Principle
TAL can decompose tyrosine to produce 4-coumaric acid, which has a strong absorption peak at 333 nm. Therefore, the activity of TAL can be calculated by measuring the OD value at 333 nm.

Note: The reagents must be stored strictly according to the preservation conditions in the above table. The reagents in different kits cannot be mixed with each other. For a small volume of reagents, please centrifuge before use, so as not to obtain sufficient amount of reagents.
Sensitivity
The analytical sensitivity of the assay is 0.12 U/mL. 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.
