Lub Centrifuge cais dab tsi?
Kev Taw Qhia:
Cov centrifuges yog cov cuab yeej siv hauv chav kuaj mob uas siv lub zog centrifugal los cais cov khoom sib xyaw raws li lawv qhov ceev. Lawv tau dhau los ua cov cuab yeej tseem ceeb hauv ntau yam lag luam, suav nrog kev kho mob, biology, chemistry, thiab ntau ntxiv. Hauv tsab xov xwm no, peb yuav tshawb nrhiav lub ntiaj teb zoo kawg nkaus ntawm centrifugation thiab kawm txog ntau yam tshuaj uas tuaj yeem cais tau siv cov cuab yeej ntse no.
I. Lub Ntsiab Cai ntawm Centrifugation:
Cov tshuab centrifuge ua haujlwm raws li lub hauv paus ntsiab lus ntawm kev tso dej tawm, qhov twg cov khoom ntom dua txav mus rau sab nraud thaum cov uas tsis ntom dua tseem nyob ze rau hauv nruab nrab. Qhov no ua tiav los ntawm kev tig cov khoom sib xyaw ntawm qhov ceev ceev, tsim kom muaj lub zog centrifugal ntau txhiab npaug muaj zog dua li lub ntiajteb txawj nqus. Los ntawm kev siv qhov sib txawv ntawm qhov ceev ntawm kev tso dej tawm, cov khoom hauv cov khoom sib xyaw tau sib cais zoo, yog li ua rau muaj kev sib cais.
II. Kev Cais Cov Cheebtsam Ntshav:
Ib qho ntawm cov kev siv tseem ceeb tshaj plaws ntawm centrifugation yog kev sib cais cov khoom ntshav, tshwj xeeb tshaj yog cov qe ntshav liab thiab dawb, plasma, thiab platelets. Los ntawm kev kho qhov ceev thiab lub sijhawm ntawm cov txheej txheem centrifugation kom zoo, qhov ceev ntawm txhua yam khoom tuaj yeem siv tau. Thaum tig cov qauv ntshav, cov khoom hnyav tshaj plaws, feem ntau yog cov qe ntshav liab, nyob hauv qab ntawm lub raj, thaum cov plasma, yog qhov sib dua tshaj plaws, sib sau ua ke rau saum toj. Cov txheej txheem sib cais no tseem ceeb heev rau ntau yam kev kho mob, xws li kev hloov ntshav, kev tshuaj xyuas hematological, thiab kev kuaj mob raws li ntshav.
III. Kev cais DNA thiab RNA:
Kev centrifugation ua lub luag haujlwm tseem ceeb hauv kev cais DNA thiab RNA los ntawm cov qauv tshuaj lom neeg. Thaum lub sijhawm rho tawm, cov cell lysates raug tsim los ntawm kev rhuav tshem cov cell thiab tso lawv cov ntsiab lus. Txawm li cas los xij, cov lysates no tseem muaj cov protein, lipids, thiab lwm yam tsis huv. Los ntawm ultracentrifugation, daim ntawv ceev tshaj plaws ntawm centrifugation, cov lysate raug tig ntawm qhov ceev heev kom cais cov nucleic acids ntawm cov khib nyiab cellular. Cov supernatant uas tshwm sim tuaj yeem sau tau, muaj DNA lossis RNA ntshiab, npaj rau kev tshuaj xyuas ntxiv lossis kev sim.
IV. Kev Sib Cais Cov Khoom Siv Rau Kev Lag Luam:
Cov centrifuges siv dav hauv ntau qhov chaw lag luam los cais cov khoom khov uas raug tshem tawm ntawm cov kua. Hauv cov chaw kho dej khib nyiab, kev ua kom huv si centrifugal siv los tshem tawm cov sludge thiab cov khoom khov, ua kom cov dej huv dua. Ib yam li ntawd, hauv kev lag luam zaub mov, centrifuges siv los cais cov khoom khov ntawm cov khoom ua kua xws li kua txiv hmab txiv ntoo lossis roj zaub. Qhov ua tau zoo thiab qhov ceev ntawm centrifugation ua rau nws yog ib qho cuab yeej tseem ceeb rau cov txheej txheem sib cais loj.
V. Kev rho tawm cov roj tseem ceeb:
Kev rho cov roj tseem ceeb los ntawm cov nroj tsuag yog lwm txoj kev siv centrifugation. Cov roj tseem ceeb yog cov khoom sib xyaw uas muaj ntxhiab tsw qab thiab saj zoo. Nrog kev pab los ntawm centrifugation, cov roj tuaj yeem sib cais los ntawm cov nroj tsuag thiab lwm yam tsis huv. Cov txheej txheem no tso cai rau kev ntshiab thiab kev sib sau ua ke ntawm cov roj tseem ceeb, uas siv dav hauv cov chaw xws li tshuaj tsw qab, aromatherapy, thiab cov khoom noj tsw qab.
Xaus lus:
Cov tshuab centrifuges yog cov cuab yeej zoo kawg uas ua tau zoo cais cov khoom sib xyaw raws li qhov ceev. Txij li cov khoom xyaw ntshav mus rau DNA thiab RNA cais tawm, los ntawm kev siv cov tshuaj hauv kev lag luam mus rau kev rho tawm roj tseem ceeb, kev centrifugation ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Nrog rau kev nce qib hauv thev naus laus zis, centrifuges txuas ntxiv hloov pauv kev tshawb fawb, kev kuaj mob, thiab cov txheej txheem kev lag luam. Kev nkag siab txog yam uas lub centrifuge tuaj yeem cais tau qhib cov cib fim tshiab rau kev tsim kho tshiab, txhim kho peb txoj kev nkag siab txog ntau yam tshuaj uas tsim peb lub ntiaj teb.
