WebONPG or lactose (i.e. have a β-D-galactose moiety), can be used in combination with -galactosidase. There are several β compounds, such as 5-bromo-4-chloro-3-indolyl-β-D-galactoside (X-gal), that form colored insoluble products after hydrolysis. These compounds are quite useful in screening for bacterial plasmid recombinants (1). Bacterial cells Webin a colored product. One such compound is o-nitrophenol-b-D-galactoside (ONPG), which when hydrolyzed forms galactose and o-nitrophenol (ONP) (Figure 1B). The compound ONP absorbs light at 420 nm whereas the precursor molecule ONPG does not. Therefore, the increase in light absorbance at 420 nm can be used to monitor b-galactosidase when …
