Cov Ntawv Thov
1. Txheeb xyuas roj ntsha thiab biochemical buffering
Tes yog qhov zoo tsis zoo, siv dav hauv kev tshawb fawb txog roj ntsha thiab biochemical kom tswj cov chaw ruaj khov ze ntawm lub cev.
Feem ntau siv nyob rau hauv:
Xov Xwm Cell Kev Tshaj Tawm Xov Xwm
Enzyme nco thiab cov protein purification
Molecular Biology Cov txheej txheem yuav tsum muaj meej pH tswj
2. Electrophoresis
Siv los ua kev sib xyaw ua ke hauv polyacrylamide hauv polyacrylamide gel electrophoresation (nplooj ntawv) thiab lwm cov tswv yim electrophetes los txhim kho kev daws teeb meem thiab reprophibility.
3. Tshuaj thiab kuaj mob cov ntawv thov
Ua haujlwm hauv cov qauv tsim tawm rau cov khoom lag luam kws tshuaj thiab tshuaj tiv thaiv, muab cov khoom siv tsis sib xws thaum lub sijhawm kev tsim khoom thiab chaw cia khoom.
4. Celliology thiab cov ntaub so ntswg engineering
Txhawb kev muaj peev xwm ntawm kev loj hlob ntawm cell thiab kev loj hlob los ntawm kev coj noj coj ua ntawm kev coj noj coj ua tsis muaj kev cuam tshuam lossis cuam tshuam nrog cov txheej txheem roj ntsha.
Cov txiaj ntsig
1. Muaj txiaj ntsig phaw hauv lub cev muaj ntau yam
Tes buffers ua tau zoo nyob ntawm nruab nrab pH, zoo tagnrho rau kev tswj hwm ib puag ncig muaj feem tau tshaj tawm cov roj ntsha ntau thiab enzymes.
2. Tsawg hlau ion Binding
Cov khoom pov thawj me me khi rau cov chaw sib txawv xws li mg²⁺ thiab kev txo qis nrog cov txheej txheem hlau-nyob lossis cov txheej txheem cell.
3. Tshuaj Muaj Peev Xwm
Tswj kev ruaj khov ua rau muaj peev xwm ntau ntawm ntau qhov kub thiab txias thiab kev cia khoom tsis muaj kev cuam tshuam tseem ceeb.
4. Tsawg UV nqus
Pob tshab rau hauv UV thiab pom pom meej, ua kom haum rau spectrophotometric thiab fluorescence cia.
5. BiCompatibility
Tsis-toxic thiab tsis cuam tshuam nrog cell metabolism, ua rau nws zoo heev rau hauv Vitro thiab Vivo daim ntawv thov.
