文献和实验邻硝基苯-β-吡喃半乳糖苷 O-nitrophenyl-β-D-galactopyranoside
缩写为 ONPG。是广泛利用于β -半乳糖苷酶活力测定的底物。水解后可游离出邻硝基酚,由于邻硝基酚在碱性条件下呈黄色( 420毫微米光吸收),所以容易进行比色定量。另外利用这种性质,还可用于分离各种代谢调节突变株。
β-Galactosidase Enzyme Assay System with Reporter Lysis Buffer
to an equal volume of Assay 2X Buffer, which contains the substrate ONPG (o-nitrophenyl-beta-D-galactopyranoside). Samples are incubated for 30 minutes, during which time the Beta-Galactosidase hydrolyzes the colorless substrate to o-nitrophenyl
