Used for the detection and quantification of polyamine oxidase (PAO) activity in plant samples, this ELISA kit enables researchers to study polyamine metabolism, which plays a key role in plant growth, development, and stress responses. It is widely applied in plant physiology and molecular biology research to assess how plants respond to environmental stresses such as drought, salinity, and pathogen attack. The kit provides a sensitive and specific method to measure PAO enzyme activity in tissue extracts, allowing for high-throughput analysis in agricultural and botanical studies aimed at improving crop resilience and productivity.
