Used for the detection and quantification of carbonic anhydrase (CA) enzyme activity in plant samples. This ELISA kit enables researchers to measure CA levels in leaves, roots, or other plant tissues, helping assess plant physiological responses to environmental stresses such as drought, high CO₂, or salinity. It is widely applied in plant biology and agricultural research to study photosynthesis efficiency, stomatal regulation, and carbon fixation. The assay provides a sensitive and specific colorimetric readout, suitable for high-throughput analysis in laboratory settings.
