Used in research settings to quantify mouse β-glucuronidase (βGD) levels in biological samples such as serum, urine, tissue homogenates, and cell culture supernatants. This ELISA kit enables detection and measurement of βGD activity, which serves as a reporter enzyme in gene expression studies, particularly in transgenic mouse models where the GUS gene is used as a marker. It is also applied in studies of lysosomal storage diseases, inflammation, and immune responses, as βGD levels can increase under certain pathological conditions. The assay provides a sensitive and specific method for high-throughput analysis in preclinical research, supporting investigations in immunology, genetics, and drug development.
