Used for the quantitative detection of plant alternative oxidase (AAO) enzyme activity in plant tissue samples. This ELISA kit enables researchers to measure AAO levels in studies related to plant respiration, stress responses, and mitochondrial function. It is commonly applied in plant physiology and biochemistry research to investigate how plants respond to environmental stresses such as cold, drought, and pathogen attack. The assay supports high-throughput analysis and provides a reliable method for monitoring changes in AAO during developmental stages or under experimental treatments.
