ONPG (2-Nitrophenyl-β-D-Galactopyranoside)

Ortho-Nitrophenyl-β-galactoside (ONPG) is a colorimetric and spectrophotometric substrate for detection of β-galactosidase activity. This compound is normally colorless. However, if β-galactosidase is present, it hydrolyzes the ONPG molecule into galactose and ortho-nitrophenol.
In Microbiology it is used in discs for the rapid detection of beta-galactosidase activity in microorganisms.
