Sodium dodecyl sulfate CAS: 151-21-3

Cov tshuaj ntxuav: SDS yog ib qho khoom xyaw uas siv ntau hauv cov khoom siv ntxuav hauv tsev, xws li cov tshuaj ntxuav tais diav thiab cov tshuaj ntxhua khaub ncaws. Nws ua haujlwm ua ib qho surfactant, txo qhov nro ntawm cov dej thiab ua rau nws tshem tawm cov av thiab roj ntawm cov chaw tau zoo dua.

Kev ntxuav hauv kev lag luam: SDS siv rau hauv kev siv ntxuav hauv kev lag luam, tshwj xeeb tshaj yog hauv kev lag luam xws li kev ua zaub mov, qhov twg nws pab tshem tawm cov roj, cov xim av, thiab cov khoom seem tawv ncauj.

Cov khoom siv tu cev: SDS pom muaj nyob rau hauv ntau yam khoom siv tu cev, xws li tshuaj zawv plaub hau, tshuaj ntxuav lub cev, thiab tshuaj txhuam hniav. Nws ua haujlwm ua tus neeg sawv cev ua npuas ncauj, pab tsim cov npuas thiab txhim kho kev nthuav dav ntawm cov khoom.

Kev rho tawm thiab ntxuav cov protein: SDS siv dav hauv kev rho tawm thiab ntxuav cov protein, tshwj xeeb tshaj yog hauv electrophoresis. Nws ua rau cov protein puas tsuaj thiab npog lawv nrog lub zog tsis zoo, uas ua rau lawv sib cais raws li qhov loj me thaum raug hluav taws xob.

Kev rho tawm DNA: SDS siv rau hauv cov txheej txheem rho tawm DNA los rhuav tshem cov cell thiab tso tawm DNA. Nws cuam tshuam cov cell membrane thiab rhuav tshem cov protein, pab txhawb kev tso tawm thiab tom qab ntawd cais tawm DNA.

Cov ntawv thov txog kev tshawb fawb txog molecular biology: SDS feem ntau siv rau hauv cov txheej txheem xws li SDS-PAGE (polyacrylamide gel electrophoresis), uas yog siv los cais cov protein raws li lawv qhov hnyav molecular. Nws kuj tseem siv ua ib feem hauv Western blotting, ib txoj kev siv los ntes cov protein tshwj xeeb hauv cov qauv.

Kev lag luam tshuaj: SDS yog siv rau hauv kev tsim cov tshuaj, suav nrog cov tshuaj pleev thiab cov tshuaj pleev, qhov twg nws pab txhawb kev yaj thiab kev sib kis ntawm cov khoom xyaw nquag.
