Used to detect and quantify β-galactosidase activity in biological samples from monkeys, this ELISA kit is particularly valuable in gene expression studies where β-gal is used as a reporter enzyme. It enables researchers to measure the efficiency of gene delivery and expression in primate models, which are often used in preclinical research. The assay is commonly applied in virology, vaccine development, and gene therapy studies to assess promoter activity or transduction efficiency in cells or tissues. High sensitivity and specificity allow for accurate measurement even in complex sample matrices such as cell lysates or tissue homogenates.
