Used for the quantitative determination of alpha-L-fucosidase (AFU) activity in rat biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is commonly applied in research settings to study liver function, as elevated AFU levels are associated with liver diseases including hepatocellular carcinoma. It is also utilized in toxicology studies to assess drug-induced liver injury in rat models. The assay helps in monitoring disease progression and evaluating the efficacy of therapeutic agents in preclinical research.
