Used in biomedical research to quantify levels of human β-hexosaminidase A enzyme in biological samples such as serum, plasma, or cell lysates. This ELISA kit is particularly valuable in studies related to Tay-Sachs disease, a genetic disorder caused by deficiency or dysfunction of this enzyme. It enables researchers to assess enzyme activity and expression in diagnostic development, therapeutic monitoring, and evaluation of potential treatments. The assay is also applied in lysosomal storage disorder research, helping to differentiate between normal, carrier, and affected individuals based on enzyme concentration. Its high sensitivity and specificity make it suitable for use in clinical laboratories and pharmaceutical research involving enzyme replacement therapies or gene therapy outcomes.
