Used in biomedical research to quantify levels of human alpha-glucosidase (GAA) enzyme in biological samples such as serum, plasma, or cell lysates. This ELISA kit is particularly valuable in studies related to Pompe disease, a genetic disorder caused by GAA deficiency, enabling researchers to assess enzyme activity, monitor therapeutic efficacy, and support diagnosis development. It is also used in drug development and clinical studies focusing on enzyme replacement therapies and gene treatments targeting lysosomal storage disorders.
