Used in biomedical research to quantify levels of human α-galactosidase enzyme in biological samples such as blood, plasma, or cell lysates. This ELISA kit is particularly valuable in studies related to Fabry disease, a lysosomal storage disorder caused by αGAL deficiency. It enables researchers to assess enzyme activity and expression in clinical samples, evaluate the effectiveness of enzyme replacement therapies, and monitor biomarker changes in patient samples. The assay is also applied in quality control during the production of recombinant α-galactosidase for therapeutic use. Its high sensitivity and specificity make it suitable for detecting low concentrations of the enzyme, supporting both diagnostic research and drug development efforts.
