N,N-Bis(2-hydroxyethyl)-2-aminoethanesulfonic acid sodium ntsev CAS: 66992-27-6

Tus neeg sawv cev pH buffering: HEPES sodium ntsev yog ib qho zwitterionic buffering compound uas pab tswj kom muaj pH ruaj khov hauv kev sim tshuaj lom neeg. Nws feem ntau siv rau hauv cov kab lis kev cai cell thiab biochemical assays, muab ib puag ncig zoo rau kev loj hlob ntawm cell thiab kev ua haujlwm ntawm enzyme.

Kev tshawb nrhiav txog cov protein: HEPES sodium ntsev yog siv dav ua ib qho buffer hauv kev ntxuav cov protein, kev piav qhia txog cov yam ntxwv, thiab kev tshuaj xyuas. Nws pab tswj cov protein kom ruaj khov thiab ua haujlwm, kom ntseeg tau tias cov txiaj ntsig raug thiab txhim khu kev qha.

Electrophoresis: HEPES sodium ntsev feem ntau yog siv ua ib qho buffer khiav hauv cov txheej txheem electrophoresis xws li SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis). Nws pab tswj pH thiab ionic zog, ua rau kev sib cais ntawm biomolecules zoo.

Cov tshuaj tsim tshuaj: HEPES sodium ntsev yog siv los ua tus neeg sawv cev hauv kev tsim cov tshuaj, suav nrog kev txhaj tshuaj thiab kev npaj tshuaj pleev. Nws ua kom muaj kev ruaj khov thiab ua tau zoo ntawm cov tshuaj thiab pab tswj lawv cov pH hauv qhov ntau yam xav tau.

Cov ntawv thov kab lis kev cai ntawm tes: HEPES sodium ntsev feem ntau siv rau hauv cov kab lis kev cai ntawm tes kom tswj tau pH ruaj khov thiab muab ib puag ncig zoo tshaj plaws rau kev loj hlob ntawm tes thiab kev muaj sia nyob. Nws pab txo qis kev hloov pauv pH uas tshwm sim los ntawm kev ua haujlwm ntawm tes thiab cov pa roj carbon dioxide.
