Used in plant biology research to measure the levels and activity of cytochrome c oxidase (COX), a key enzyme in the mitochondrial electron transport chain. Helps assess mitochondrial function and respiratory capacity in plant cells under various physiological and stress conditions. Widely applied in studies related to plant metabolism, oxidative stress, senescence, and responses to environmental factors such as temperature, light, and pollutants. Enables quantitative analysis in experiments aiming to understand energy production and cellular respiration in plants. Suitable for use with plant tissue extracts where COX expression needs to be monitored accurately and sensitively.
