Usage of X-Gal
1. Chromogenic Substrate for β-Galactosidase Enzyme Assay
Indigogenic chromogenic substrate for β-galactosidase. It forms insoluble deep blue precipitate after enzymatic hydrolysis in biological samples.
It is widely used for blue-white screening in molecular cloning and histochemical staining for gene expression analysis in molecular biology formulations.
2.Bacterial Strain Screening & Colony Identification Reagent
Specific color indicator for strains expressing lacZ gene. Positive colonies show obvious blue color for easy visual distinction.
Applied in microbiology culture medium preparation for recombinant bacteria screening and microbial colony counting projects.
3.Reporter Gene Histochemical Staining Marker
Classic substrate for lacZ reporter gene detection, enabling in-situ visualization of target gene expression in tissue and cell samples.
Commonly formulated into staining working solution for cell biology, transgenic animal and plant gene localization research.
4.Fine-Chemical Chromogenic Indicator Intermediate for Life Science R&D
High-purity halogenated indole glycoside compound with stable chromogenic characteristics for bioassay kit custom development.
Consistent batch quality supports formulation optimization for molecular detection kits and high-throughput genetic screening assays.
