6-Bromo-2-naphthyl b-D-galactopyranoside

6-溴-2-奈基-beta-D-半乳糖苷

6-Bromo-2-naphthyl β-D-galactopyranoside is a chromogenic substrate commonly used for the detection of the enzymatic activity of β-galactosidase. It can produce a yellow precipitate upon hydrolysis by β-galactosidase, indicating the presence of the enzyme. It is often used in molecular biology applications to detect gene expression or to monitor cloning efficiency.
