3-NITROPHENYL-BETA-D-GALACTOPYRANOSIDE CAS: 3150-25-2
Kev kuaj pom ntawm beta-galactosidase kev ua haujlwm: ONPG feem ntau yog siv los txiav txim siab qhov muaj thiab kev ua haujlwm ntawm beta-galactosidase hauv ntau yam qauv tshuaj lom neeg, xws li cov kab mob bacterial lossis cell lysates. Kev tsim cov o-nitrophenol, uas muaj xim daj, tuaj yeem ntsuas tau yooj yim siv lub spectrophotometer.
Kev tshawb fawb txog kev qhia txog noob caj noob ces: ONPG feem ntau siv rau hauv kev tshawb fawb txog molecular biology los kawm txog kev qhia txog noob caj noob ces. Los ntawm kev sib xyaw tus neeg txhawb nqa ntawm cov noob caj noob ces uas txaus siab nrog cov noob caj noob ces uas encoded beta-galactosidase, cov kws tshawb fawb tuaj yeem ntsuas qhov kev ua haujlwm ntawm tus neeg txhawb nqa no los ntawm kev ntxiv ONPG thiab ntsuas qhov tshwm sim ntawm o-nitrophenol. Txoj kev no, hu ua beta-galactosidase reporter assay, muab cov ntaub ntawv hais txog kev ua haujlwm ntawm cov noob caj noob ces.
Kev txheeb xyuas cov kab mob: Qee cov kab mob tsim cov beta-galactosidase, thaum lwm tus tsis ua. ONPG tuaj yeem siv ua ke nrog lwm cov kev kuaj biochemical los txheeb xyuas cov hom kab mob raws li lawv lub peev xwm los hydrolyze ONPG. Txoj kev no feem ntau siv rau hauv kev kuaj mob thiab chaw kuaj mob microbiology.
Kev tshuaj xyuas cov tshuaj enzyme inhibitors lossis activators: ONPG siv tau los tshuaj xyuas cov tshuaj uas hloov pauv kev ua haujlwm ntawm beta-galactosidase. Los ntawm kev ntsuas qhov kev ua haujlwm ntawm enzyme nyob rau hauv qhov muaj ntau yam tshuaj sib txawv, cov kws tshawb fawb tuaj yeem txheeb xyuas cov tshuaj inhibitors lossis activators uas tuaj yeem tshawb xyuas ntxiv rau lawv cov peev xwm kho mob.
