Cov Ntawv Thov
1. Kev txheeb xyuas roj ntsha thiab biochemical tsis
Mes poov tshuaj ntsev tau dav siv raws li qhov zoo tsis zoo hauv kev tshawb fawb txog kev siv roj ntsha roj ntsha kom tswj tau ntev li cov kua qaub me ntsis.
Feem ntau siv nyob rau hauv:
Xov Xwm Cell Kev Tshaj Tawm Xov Xwm
Enzyme nco thiab cov protein purification
Molecular biology protrict uas precise py yog qhov tseem ceeb.
2. Kws ua tshuaj thiab cov qauv tshuaj ntsuam
Siv los ua kom tsis txhob siv tshuaj yeeb yaj kiab thiab hauv vitro kuaj xyuas uas yuav tsum muaj acidic pH zoo li qub.
3. Electrophoresis
Ua ntawv thov hauv polyacrylamide gel electrophoresis (nplooj) thiab lwm yam qauv electrophictes kom zoo rau cov teeb meem acidic me ntsis.
4. Biochemical cia
Kev txhawb nqa cov kev cuam tshuam nrog cov kev cuam tshuam nrog cov enzymes thiab biomolecules uas nquag lossis ruaj khov nyob rau hauv hom ph 5.5-6.7 ntau.
Cov txiaj ntsig
1. Optimal buffering ntawm me ntsis acidic ph
Muab cov txheej txheem zoo tshaj plaws rau 6.1, uas yog qhov zoo tagnrho rau ntau cov txheej txheem biological rhiab rau cov qib me.
2. Tsawg hlau ion Binding
Cov khoom ua pov thawj tsawg kawg nkaus kev sib cuam tshuam nrog cov hlau ions, khaws cov enzyme cofactors thiab cov dej num hlau.
3. Siab Solubility
Yooj yim yaj hauv cov kev daws teeb meem aqueous, pab txhawb kev npaj ntas kev yooj yim.
4. Tshuaj lom neeg thiab cov hluav taws xob ruaj khov
Tswj tau tus cwj pwm tsis muaj peev xwm ua tau muaj peev xwm sim ua ntej, ua kom muaj txiaj ntsig zoo.
5. Tsawg UV tshem
Tsis cuam tshuam nrog UV spectrophotometric ntsuas, tso cai rau nucleic acid thiab cov protein ntau.
Tag
Mes poov tshuaj ntsev (CAST 39946-25-3) yog qhov siv roj ntsha ua kom zoo rau kev saib xyuas lub hom acidic me ntsis (5.5-6.7). Nws zoo buffering muaj peev xwm, tsis muaj tshuaj lom neeg ua rau nws muaj kev tsis muaj peev xwm, thiab precision hauv cov ntawv thov kev tshawb fawb hauv lub neej.
