TOPS CAS: 40567-80-4 Chaw tsim tshuaj paus Nqe

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

MESNa ua hauj lwm raws li ib tug haib txo tus neeg sawv cev, muaj peev xwm hloov disulfide bonds (-SS-) nyob rau hauv cov proteins rau hauv sulfhydryl (-SH) pawg.Qhov kev txo qis no yog qhov tseem ceeb hauv ntau yam kev siv txuj ci, suav nrog kev tsom xam cov protein, kev ua kom huv, thiab kev tsim cov protein.

Qee cov ntawv thov tshwj xeeb ntawm MSNa suav nrog:

Protein Denaturation: MESNa tuaj yeem siv los ua cov protein ntau los ntawm kev rhuav tshem cov ntawv cog lus disulfide, yog li nthuav tawm cov qauv protein thiab ua kom yooj yim rau kev soj ntsuam ntxiv lossis kev ua kom huv ntawm cov protein.

Txo Protein Aggregation: MESNa tuaj yeem tiv thaiv kev sib sau ua ke ntawm cov protein los ntawm kev txo cov nyiaj disulfide, ua kom muaj protein ntau ruaj khov thiab solubility hauv kev daws.

Protein Labeling: MESNa tuaj yeem siv los qhia cov ntawv lossis kev hloov kho ntawm cov cysteine ​​residues hauv cov protein los ntawm kev rhuav tshem cov nyiaj disulfide thiab nthuav tawm cov pab pawg sulfhydryl (-SH).

Protein Refolding: MESNa yog siv los pab cov protein refolding tom qab denaturation los ntawm kev txo cov disulfide bonds thiab pab nyob rau hauv qhov tseeb tsim ntawm protein cov qauv.
