Used in biomedical research to quantify pig alpha-glucosidase (GAA) enzyme levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is particularly valuable in studies related to glycogen storage disease type II (Pompe disease), where GAA enzyme activity is deficient. It enables researchers to assess enzyme expression, evaluate therapeutic efficacy of enzyme replacement therapies, and monitor disease progression in porcine models. The assay provides a sensitive and specific means to measure GAA concentration, supporting preclinical research and veterinary diagnostics.
