Used for the detection and quantification of carbonic anhydrase (CA) enzyme activity in biological samples from ducks. This ELISA kit enables researchers to measure CA levels in tissues or fluids, supporting studies in avian physiology, respiratory function, and metabolic research. It is particularly useful in veterinary diagnostics and poultry health monitoring, where changes in CA activity may indicate metabolic disorders, respiratory diseases, or environmental stress responses. The assay provides a sensitive and specific method for high-throughput analysis in research laboratories focused on avian biochemistry and disease mechanisms.
