Used in plant molecular biology and genetic engineering research to detect GUS reporter gene expression. The kit allows visualization of gene activity in plant tissues, commonly used in promoter analysis, transformation efficiency studies, and tissue-specific expression patterns. It provides a ready-to-use solution for histochemical staining, enabling clear localization of β-glucuronidase (GUS) enzyme activity in leaves, roots, seeds, and other plant parts without additional preparation. Ideal for transgenic plant screening and developmental biology studies.
