Used for the quantitative measurement of alpha-L-fucosidase (AFU) activity in mouse biological samples such as serum, plasma, and tissue homogenates. This ELISA kit is commonly applied in research settings to study liver function, tumor progression, and metabolic disorders, as elevated AFU levels are associated with hepatocellular carcinoma and other pathological conditions. It enables high-throughput analysis with high sensitivity and specificity, making it suitable for preclinical studies and biomarker validation in mouse models.
