Used for the quantitative measurement of β-glucuronidase (βGD) activity in mouse biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. This ELISA kit enables researchers to assess lysosomal enzyme activity, which is important in studies related to metabolic disorders, gene expression, and promoter activity in transgenic mouse models where βGD serves as a reporter enzyme. The assay is useful in monitoring disease progression in models of inflammation, infection, and lysosomal storage diseases. It provides a sensitive and specific method to detect enzymatic activity, allowing high-throughput analysis in preclinical research and drug development.
