Kev Taw Qhia Txog Centrifugation: Yuav Ua Li Cas Centrifuge Cais Cov Khoom Sib Xyaws
Kev siv centrifugation yog ib txoj kev siv dav dav hauv chav kuaj uas siv cov ntsiab cai ntawm kev tso dej thiab lub zog centrifugal los cais cov khoom sib xyaw raws li lawv qhov ceev. Cov txheej txheem no yog qhov tseem ceeb hauv ntau qhov kev tshawb fawb thiab kev kho mob uas qhov kev sib cais ntawm cov khoom sib txawv hauv cov qauv yog qhov xav tau rau kev tshuaj xyuas, kev ntxuav, lossis kev cais tawm. Hauv tsab xov xwm no, peb yuav tham txog cov ntsiab cai tseem ceeb ntawm kev siv centrifugation thiab nkag mus rau hauv ntau yam kev siv thiab hom centrifuges siv hauv ntau yam lag luam.
1. Cov Ntsiab Cai ntawm Centrifugation
Ua ntej yuav nkag siab txog qhov nyuaj ntawm kev centrifugation, nws yog ib qho tseem ceeb kom nkag siab txog cov ntsiab cai tom qab cov txheej txheem no. Lub hauv paus ntsiab lus tseem ceeb uas koom nrog ntawm no yog kev siv lub zog centrifugal los cais cov khoom sib xyaw. Thaum ib qho qauv raug muab tso rau hauv lub centrifuge thiab tig ntawm qhov ceev ceev, cov khoom me me lossis cov molecule txav mus rau hauv qab, thaum cov khoom me me uas tsis ntom ntom feem ntau nyob ze rau saum toj. Qhov kev sib cais no tshwm sim vim yog kev tso dej ntawm cov khoom me me, uas tau nrawm los ntawm lub zog centrifugal.
2. Ntau Hom Centrifuges
Muaj ntau hom centrifuges muaj, txhua hom yog tsim los rau cov kev siv tshwj xeeb. Ib hom uas siv ntau tshaj plaws yog lub centrifuge uas siv tau rau saum rooj, uas muaj ntau yam siv tau thiab siv tau rau hauv chaw soj nstuam rau cov haujlwm sib cais niaj hnub. Lwm hom yog ultracentrifuge, uas muaj peev xwm ncav cuag qhov ceev ceev heev thiab tsim cov zog centrifugal muaj zog, ua rau nws zoo tagnrho rau cov haujlwm uas xav tau kev sib cais cov khoom me me uas muaj qhov ceev tsawg heev.
Cov centrifuges uas txias lawm, ntawm qhov tod tes, muaj cov tshuab cua txias uas tso cai rau kev sib cais cov qauv uas rhiab heev rau qhov kub thiab txias yam tsis muaj kev cuam tshuam rau lawv qhov kev ua haujlwm. Cov centrifuges no pom tias siv dav hauv cov ntawv thov xws li molecular biology, qhov twg kev tswj qhov kub thiab txias kom raug yog qhov tseem ceeb.
3. Cov Ntawv Thov Kho Mob
Hauv kev kuaj mob hauv tsev kho mob, kev siv lub tshuab centrifugation ua lub luag haujlwm tseem ceeb hauv kev tshuaj xyuas thiab kev sib cais cov ntshav. Los ntawm kev tig cov ntshav hauv lub tshuab centrifuge, cov kws kho mob tuaj yeem cais cov khoom sib txawv, xws li cov qe ntshav liab, cov qe ntshav dawb, thiab cov ntshav plasma. Qhov kev sib cais no ua rau muaj peev xwm nrhiav tau thiab kuaj mob ntau yam kab mob thiab tej yam mob, nrog rau kev sau cov khoom ntshav tshwj xeeb rau kev kho mob.
4. Cov Ntawv Thov Kev Lag Luam
Kev siv centrifugation kuj siv dav hauv ntau yam txheej txheem kev lag luam. Piv txwv li, hauv kev lag luam khoom noj thiab dej haus, centrifuges siv los cais cov kua thiab cov khoom khov thiab ua kom cov kua txiv hmab txiv ntoo, cawv, thiab lwm yam dej haus huv. Tsis tas li ntawd, centrifuges ua lub luag haujlwm tseem ceeb hauv cov chaw kho dej khib nyiab, qhov chaw uas lawv pab cais cov khoom khov tawm ntawm dej, ua rau muaj kev nyab xeeb pov tseg lossis rov siv dua cov dej kho.
5. Kev Tshawb Fawb thiab Biotechnology
Hauv cov chaw soj ntsuam thiab cov chaw biotechnology, centrifugation siv dav hauv ntau yam kev siv. Nws feem ntau siv los ntxuav cov protein, cais cov cell organelles, cais cov nucleic acids, thiab sau cov cell los ntawm cov kab lis kev cai cell. Cov txheej txheem no yog qhov tseem ceeb rau kev ua cov kev sim, kawm txog cov khoom tshwj xeeb ntawm cell, thiab tsim cov kev daws teeb meem kho mob.
Xaus lus
Kev siv centrifugation yog ib txoj kev tseem ceeb uas tso cai rau kev sib cais cov khoom sib xyaw hauv ntau yam kev tshawb fawb, kev kho mob, thiab kev lag luam. Los ntawm kev siv lub zog ntawm lub zog centrifugal, cov kws tshawb fawb thiab cov kws tshaj lij thoob plaws ntau qhov chaw tuaj yeem cais thiab tshuaj xyuas cov khoom sib txawv hauv cov qauv kom raug. Qhov ua tau ntau yam thiab ntau yam kev siv ntawm centrifugation ua rau nws yog ib qho cuab yeej tseem ceeb hauv cov chaw soj nstuam thoob ntiaj teb, pab txhawb rau cov haujlwm xws li cov txheej txheem kuaj mob niaj hnub mus rau kev tshawb fawb tshiab.
