Dilution of Sample
The recommended dilution factor for different samples is as follows (for reference only):
Sample type | Dilution factor |
10% Ginger tissue homogenization | 1 |
10% Chinese yam tissue homogenization | 1 |
10% Corn tissue homogenization | 1 |
10% Pear tissue homogenization | 1 |
Note: For the dilution of other sample types, please do pretest to confirm the dilution factor.
Detection Principle
Polyphenol oxidase (PPO) can catalyze phenolic compounds into quinone substances. The latter has specific absorption at 410 nm. The activity of PPO can be calculated indirectly bymeasuring the OD value at 410 nm.
