Used in biomedical research to quantify levels of human α-L-fucosidase (AFU) enzyme in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is particularly valuable in liver disease studies, as elevated AFU activity has been associated with hepatocellular carcinoma and other hepatic disorders. It enables researchers to assess AFU as a potential diagnostic or prognostic biomarker. The assay is also applied in metabolic disorder research, especially in conditions involving glycoprotein metabolism. Due to its high sensitivity and specificity, the kit supports accurate detection of AFU in clinical and experimental settings, aiding in both disease monitoring and therapeutic evaluation.
