Cov Ntawv Thov
1. Kev txheeb xyuas biological
Cov Txheej Txheem Txheej Txheem yog dav siv nyob rau hauv molecular biology, biochemistry, thiab Biology Cell raws li kev ua kom zoo nrog kev txhim kho pH.
Nws ua ke ua ke nrog cov roj acetic nrog actic acid, sib sau ua ke nrog kev txhim kho tsis muaj peev xwm ua tau muaj peev xwm ua tau zoo me ntsis rau cov chaw ib puag ncig me ntsis.
2. Electrophoresis thiab Gel Tshuab
Ua haujlwm nyob rau hauv agarose thiab polyacrylamide gel electrophores rau DNA, RNA, tshwj xeeb yog qhov twg tsis muaj cua sov thiab tsawg heev qhov twg yog qhov xav tau.
3. Protein thiab nucleic acid ua haujlwm
Siv hauv kev ua yeeb yam hauv kev ua yeeb yam, tshuaj tiv thaiv tshuaj tiv thaiv kab mob, thiab DNA / RNA lim cov txheej txheem uas ruaj khov, tsis muaj kev cuam tshuam.
4. Cell thiab Cov Ntaub Ntawv Kab Cai
Haum rau buffering biological fluids thiab kev coj ua kev sib cav, tshwj xeeb tshaj yog nyob rau hauv cov tshuab uas cov pa roj carbon dioxide tsis zoo.
5. Kws ua tshuaj thiab cov qauv tshuaj ntsuam
Muaj nyob hauv cov vitro kuaj xyuas cov tshuaj tiv thaiv thiab cov qauv roj ntsha xav kom meej meej lub pH tswj ze neutrally.
Cov txiaj ntsig
✅ Ph ntawv
Saib xyuas cov pH ruaj khov hauv lub cev, zoo tagnrho rau feem ntau roj ntsha thiab cov xov tooj ntawm tes.
✅ Tsawg ionic zog
Cov tswv yim acetate cov khoom pov thawj tsis tshua muaj erion ionic, txo cov hluav taws xob hauv electrophoresis, txo tus qauv overheating thiab txhim kho kev daws teeb meem.
✅ Tau sib haum nrog hlau ions
Tsawg hlau ion chelation ua rau nws tau tshaj li cov enzymes thiab kev tiv thaiv.
✅ solubility siab thiab ruaj khov
Dawb soluble hauv dej thiab ruaj khov nyob rau hauv cov kev kuaj txheem ntawm cov qauv, ua rau nws yooj yim thiab txhim khu kev qha rau kev siv niaj hnub.
✅ biologically inert
Tsis-toxic thiab tsis cuam tshuam nrog enzymatic lossis cellular cov txheej txheem, ua rau nws zoo haum rau kev nkag siab ntawm tes thiab kev ua haujlwm ntawm tes.
Tag
Cov kais dej (CAS 29915-38-6) yog ib tug ntseeg tau thiab biocompib li alkaline tsis siv dav hauv biochiemistry, elececular biology, electrophoresis, thiab ntaub ntawv thov tshuaj. Nws cov kev cuam tshuam zoo heev, kev cuam tshuam loj heev, thiab kev cuam tshuam biomolecules, thiab cov cuab yeej siv tseem ceeb rau cov neeg txawj ntse rau ib puag ncig me nyuam.
