Used for the quantitative measurement of ornithine decarboxylase (ODC) enzyme activity in plant tissue samples. This kit enables researchers to assess ODC levels, which play a key role in polyamine biosynthesis, helping to study plant growth, development, and stress responses. It is widely applied in plant physiology and molecular biology research to monitor changes in enzyme activity under various environmental conditions such as drought, salinity, or pathogen attack. The assay is suitable for high-throughput analysis and provides a reliable tool for understanding the regulation of polyamine metabolism in plants.
