TOPS CAS:40567-80-4 Tus nqi tsim khoom

Sodium 3-(N-ethyl-3-methylanilino)propanesulfonate, tseem hu ua MESNa, muaj cov nyhuv tshwj xeeb thiab daim ntawv thov hauv biochemistry thiab molecular biology. Nws yog siv los ua tus neeg sawv cev txo qis rau kev tiv thaiv cov thiol (-SH) pawg hauv cov protein thiab peptides.

MESNa ua haujlwm ua tus neeg sawv cev txo qis muaj zog, muaj peev xwm hloov cov disulfide bonds (-SS-) hauv cov protein mus rau hauv cov pawg sulfhydryl (-SH). Cov txheej txheem txo qis no yog qhov tseem ceeb hauv ntau yam kev siv tshawb fawb, suav nrog kev tshuaj xyuas protein, kev ntxuav, thiab kev tsim cov protein.

Qee cov ntawv thov tshwj xeeb ntawm MESNa suav nrog:

Kev Ua Kom Protein Denaturation: MESNa siv tau los ua kom cov protein denature los ntawm kev rhuav tshem cov disulfide bonds, yog li ntawd nthuav tawm cov qauv protein thiab pab txhawb kev tshuaj xyuas ntxiv lossis kev ntxuav protein.

Txo Kev Sib Sau Ua Ke ntawm Cov Protein: MESNa tuaj yeem tiv thaiv kev sib sau ua ke ntawm cov protein los ntawm kev txo cov disulfide bonds, ua kom muaj kev ruaj khov ntawm cov protein thiab kev yaj hauv cov kua.

Kev Sau Npe Protein: MESNa siv tau los qhia cov ntawv lo lossis kev hloov kho ntawm cov cysteine ​​​​​​cov residues tshwj xeeb hauv cov protein los ntawm kev rhuav tshem cov disulfide bonds thiab nthuav tawm cov sulfhydryl (-SH) pawg.

Kev Rov Qhwv Cov Protein: MESNa yog siv los pab cov protein rov qhwv tom qab denaturation los ntawm kev txo cov disulfide bonds thiab pab tsim cov qauv protein kom raug.
