Used in research settings to detect and quantify manganese peroxidase (MnP) enzyme activity produced by plants and fungi, particularly in studies related to lignin degradation and bioremediation. The ELISA kit format allows for high-sensitivity measurement of MnP in environmental and plant tissue samples, supporting investigations in plant physiology, soil microbiology, and bioenergy research. It is commonly applied in monitoring enzyme expression during biomass decomposition and in assessing the efficiency of fungal or plant-based systems in breaking down organic pollutants.
