2-ニトロフェニルβ-D-ガラクトピラノシド 化学特性,用途語,生産方法
外観
白色～わずかにうすい褐色, 結晶性粉末～粉末
溶解性
水, メタノールにやや溶けにくく、エタノールに溶けにくく、ジエチルエーテルにほとんど溶けない。
用途
β-D-galactosidaseの測定用基質。
説明
2-Nitrophenyl-β-D-galactopyranoside (ONPG) is a colorimetric and spectrophotometric substrate for detecting β-galactosidase activity. This compound is usually colorless. However, if β-galactosidase is present, it hydrolyzes the ONPG molecule into galactose and ortho-nitrophenol. The latter compound has a yellow color that can be used to check for enzyme activity utilizing a colorimetric assay (at 420 nm wavelength). β-Galactosidase is required for lactose utilization, so the intensity of the color produced can be used to measure the enzymatic rate. Though ONPG mimics lactose and is hydrolyzed by β-galactosidase, it cannot act as an inducer for the lac operon. Without another lactose analog that can act as an inducer, such as isopropyl β-D-1-thiogalactopyranoside (IPTG), β-galactosidase will not be transcribed and ONPG will not be hydrolyzed.
