| Product Introduction | Polyphenol oxidase (PPO) is an enzyme involved in the oxidation of phenolic compounds, a critical step in the formation of humic substances and the stabilization of soil organic matter. High PPO activity can indicate active humification processes. This kit measures PPO activity colorimetrically using a standard phenolic substrate like pyrogallol or L-DOPA. |
| Product Application | • Soil organic matter humification and stabilization studies • Carbon sequestration research • Impact of fire or disturbance on soil biochemistry • Litter decomposition dynamics |
| Product Advantages | • Key Humification Enzyme: Specifically targets an enzyme central to the transformation of labile carbon into more stable soil organic matter pools. • Visible Spectrophotometer Method: Uses a common phenolic substrate that produces a colored product (purpurogallin or dopachrome) measurable with standard lab spectrophotometers. • Activity-Stabilizing Extractants: Includes reagents to help extract and stabilize the often particle-bound PPO enzyme from soil, improving assay reliability. • Indicator of C Stability: Provides a functional metric related to long-term carbon storage potential in soils, beyond simple organic carbon content measurements. |
