Used to measure carbonic anhydrase activity in plant tissues, this ELISA kit enables researchers to quantify the efficiency of CO₂ fixation in photosynthesis studies. It is widely applied in plant physiology and climate change research to evaluate how different environmental conditions, such as drought, high temperature, or elevated CO₂ levels, affect the carbon concentration mechanism in plants. The kit supports the development of improved crop varieties with enhanced photosynthetic efficiency and stress tolerance. It is also used in screening genetically modified plants aimed at increasing biomass production or carbon sequestration capacity.
