For research use only.

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 by measuring the OD value at 410 nm.
Synonyms PPO
Sample Type Plant tissue
Detection Method Colorimetric method
Detection Instrument Spectrophotometer (410 nm)
Research Area Plant Physiology Series
Storage This product can be stored at 2-8°C for 12 months with shading light.
Valid Period 12 months
Precision inter-assay CV: 9.8% | intra-assay CV: 4.6%
Sample Volume 0.3 mL(tissue homogenate)
Assay Time 1 h

The recommended dilution factor for different samples is as follows (for reference only):

Sample Type Dilution Factor
10% Pepper tissue homogenization 1
10% Corn tissue homogenization 1
10% Potato tissue homogenization 1
10% Ginger tissue homogenization 1
10% Apple tissue homogenization 1
10% Pear tissue homogenization 1
10% Chinese yam tissue homogenization 1

The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4). For the dilution of other sample types, please do pretest to confirm the dilution factor.
