Used in plant molecular biology research to detect and quantify β-glucuronidase (GUS) enzyme activity, commonly employed as a reporter gene in transgenic plants. The ELISA kit allows researchers to assess gene expression levels by measuring GUS protein concentration in plant tissue extracts with high sensitivity and specificity. Widely applied in studies involving promoter activity, transformation efficiency, and tissue-specific expression patterns. Suitable for high-throughput screening in genetic engineering and functional genomics projects.
