3-morpholinopropanesulfonic acid hemisodium ntsev CAS: 117961-20-3

pH buffering: MOPS-Na muaj txiaj ntsig zoo rau kev tswj hwm pH ruaj khov hauv qhov ntau ntawm lub cev (pH 6.5-7.9). Nws qhov xwm txheej zwitterionic tso cai rau nws tiv taus kev hloov pauv hauv pH thaum ntxiv cov kua qaub lossis cov hauv paus, ua rau nws muaj txiaj ntsig zoo rau kev tswj hwm cov xwm txheej zoo tshaj plaws hauv cov kab lis kev cai ntawm tes thiab ntau yam kev sim.

Kev tshawb nrhiav txog cov protein thiab enzyme: MOPS-Na feem ntau siv rau hauv kev ntxuav cov protein, kev piav qhia txog cov yam ntxwv, thiab kev ruaj khov. Nws lub peev xwm buffering thiab kev sib raug zoo nrog ntau cov enzymes thiab cov protein ua rau nws tsim nyog rau kev tswj hwm pH xav tau thaum lub sijhawm no. MOPS-Na kuj tseem siv tau rau hauv kev ntsuam xyuas enzyme, qhov twg kev tswj hwm pH kom meej yog qhov tseem ceeb rau kev ntsuas qhov tseeb ntawm kev ua haujlwm enzymatic.

DNA thiab RNA electrophoresis: MOPS-Na feem ntau siv ua ib qho buffer hauv nucleic acid gel electrophoresis. Nws muab cov pH ntau yam thiab lub zog ionic, uas ua rau muaj kev sib cais zoo ntawm DNA thiab RNA fragments. Qhov kev nqus UV qis ntawm MOPS-Na yog qhov zoo hauv daim ntawv thov no, vim nws tsis cuam tshuam nrog kev ntsuas spectrophotometric ntawm nucleic acids.

Cov khoom siv rau kev cog qoob loo ntawm tes: MOPS-Na siv rau hauv cov khoom siv rau kev cog qoob loo ntawm tes kom tswj tau pH thiab osmotic sib npaug uas tsim nyog rau kev loj hlob ntawm tes thiab kev muaj sia nyob. Nws qhov sib xws nrog ntau hom tes thiab tsis muaj tshuaj lom ua rau nws yog tus neeg sawv cev zoo tshaj plaws rau kev tswj hwm cov xwm txheej ntawm lub cev hauv kev sim cog qoob loo ntawm tes.

Kev tshawb fawb txog tshuaj thiab kab mob: MOPS-Na siv rau ntau yam kev tshawb fawb txog tshuaj thiab kab mob, xws li kev ntsuas qhov enzyme kinetics, kev tshuaj ntsuam tshuaj, thiab kev tshawb fawb txog cov teebmeem ntawm pH rau cov txheej txheem cellular. Nws lub peev xwm buffering pab txo cov khoom cuav uas nyob ntawm pH thiab xyuas kom meej tias cov txiaj ntsig txhim khu kev qha thiab rov ua dua tau.
