Used for the quantitative measurement of GUSβ (β-glucuronidase) enzyme activity in mouse biological samples such as tissue lysates, cell culture supernatants, and urine. This ELISA kit enables researchers to assess gene expression in studies involving reporter gene assays, particularly in transgenic mouse models where GUSβ is used as a marker. It is commonly applied in molecular biology and genetic research to evaluate promoter activity, validate gene targeting, and monitor transgene expression. The assay provides high sensitivity and specificity, allowing accurate detection of enzymatic activity without interference from other mouse enzymes. Ideal for high-throughput screening and longitudinal studies in preclinical research.
