Used to measure alanine aminotransferase (ALT) enzyme activity in duck biological samples such as serum or liver homogenates. This ELISA kit is specifically designed for research in veterinary science and poultry health, helping to assess liver function and detect liver damage in ducks. It is commonly applied in studies related to infectious diseases, toxicology, and metabolic disorders in waterfowl. The assay enables quantitative analysis, supporting monitoring of disease progression and evaluation of therapeutic interventions in both experimental and farm settings.
