Used in research settings to quantify diamine oxidase (DAO) enzyme levels in plant samples. This kit enables scientists to study the role of DAO in plant metabolism, particularly in the breakdown of polyamines involved in growth, development, and stress responses. It is valuable in plant physiology and biochemistry studies, helping assess how plants respond to environmental stresses such as drought, salinity, or pathogen attack. The assay supports high-throughput analysis and provides a reliable method for monitoring changes in DAO activity under experimental conditions.
