indlela yokuhlukanisa nge-centrifugation

Isingeniso ku-Centrifugation kanye nokubaluleka kwayo ezinqubweni zokuhlukanisa

I-Centrifugation iyindlela esetshenziswa kabanzi ezimbonini ezahlukene kanye nasezindaweni zocwaningo zokuhlukanisa izingxube ezingafani ngokusekelwe kubukhulu bezinhlayiya kanye nobuningi bazo. Kungakhathaliseki ukuthi kusezilabhorethri zezokwelapha, ezimbonini zemithi, noma ocwaningweni lwezemvelo, ukubaluleka kwe-centrifugation ekufezeni ukuhlukaniswa okuphumelelayo akunakuphikiswa.

Lesi sihloko sihlose ukunikeza umhlahlandlela ophelele wokuthi ungahlukanisa kanjani izinto ngempumelelo usebenzisa i-centrifugation. Sizoxoxa ngesimiso se-centrifugation, sihlole izinhlobo ezahlukene ze-centrifuge, sihlolisise izindlela ezahlukene zokuhlukanisa, siqokomise izici ezibalulekile ezithonya ukusebenza kahle kokuhlukanisa, bese siphetha ngezinye izindlela zokusebenzisa le ndlela.

Ukuqonda Isimiso Sokugqamisa I-Centrifugation

I-Centrifugation isebenza ngesimiso sokuthuthwa kwenhlabathi, lapho ukusetshenziswa kwamandla e-centrifugal kubangela ukuthi izinhlayiya eziqinile ziye phansi, zakha i-pellet, kuyilapho izinhlayiya ezikhanyayo zihlala ku-supernatant. Lokhu kuhlukaniswa kufezwa ngenxa yomehluko wobuningi bezinhlayiya, ukuma, usayizi, kanye nokusebenzisana kwazo nendawo ezungezile.

Izinhlobo ze-Centrifuges kanye nezicelo zazo

Kunezinhlobo ezahlukene zama-centrifuge atholakalayo, kufaka phakathi ama-ultracentrifuge, ama-microcentrifuge, kanye nama-centrifuge ashesha kakhulu, ngalinye lenzelwe ukuhlangabezana nezidingo ezithile zokuhlukanisa. Ama-Ultracentrifuge, isibonelo, ayakwazi ukukhiqiza amandla aphezulu kakhulu e-centrifugal, okwenza kube nokuhlukaniswa kwezinhlayiya ebangeni le-nanometer. Ngakolunye uhlangothi, ama-microcentrifuge aqinile futhi asetshenziswa kakhulu emalabhorethri emitholampilo ukuze kuhlukaniswe amasampula njalo.

Izindlela Zokuhlukanisa Ezisetshenziswa Ekusebenzeni Kwe-Centrifugation

I-Centrifugation isebenzisa izindlela ezahlukene zokuhlukanisa, kuye ngohlobo lwesampula kanye nomphumela ofiselekayo. Lezi zindlela zifaka phakathi i-differential centrifugation, i-rate-zonal centrifugation, i-density gradient centrifugation, kanye ne-isopycnic centrifugation.

Ukuhlukanisa i-centrifugation kwenza kube nokuhlukaniswa kwezinhlayiya ngokusekelwe kubukhulu bazo kanye nobuningi bazo. Ngokufaka ingxube emijikelezweni elandelanayo yokuhlukanisa ngesivinini esikhulu, izinhlayiya ezincane ziqala ngokungcola, kulandelwe izinhlayiya ezinkulu, okuholela ekuhlukaneni.

Ngakolunye uhlangothi, i-centrifugation yezinga-zonal ihilela ukulayisha isampula endaweni yokulinganisa enobukhulu obuhlukahlukene. I-centrifugation ibe isibangela ukuthi izinhlayiya zihambe nge-gradient ngokusekelwe kusayizi wazo nesimo sazo, ekugcineni zakhe amabhande ahlukile.

I-centrifugation ye-density gradient isebenzisa i-density gradients edalwe izinto ezifana ne-sucrose noma i-cesium chloride. Izinhlayiya zithutha nge-gradient zize zifinyelele esifundeni sobuningi obulinganayo, okuholela ekuhlukaneni. Le ndlela iwusizo kakhulu lapho kuhlukanisa ama-organelle noma izinhlobo ezahlukene zamaseli.

Ekugxilweni kwe-isopycnic, izinhlayiya zihlukaniswa ngokusekelwe ekubuthweni kwazo okuthambile. Ngokufaka isampula ku-gradient lapho izinhlayiya zinobukhulu obufanayo nobendawo ezungezile, izinhlayiya ziyantanta noma zicwila kuze kube yilapho kufinyelelwa ukulingana. Le ndlela ithola ukusetshenziswa ekuhlukanisweni kwe-DNA ne-RNA.

Izici Ezithinta Ukusebenza Kahle Kokucisha Ugesi

Izici eziningana zithonya ukusebenza kahle kanye nokusebenza kahle kwe-centrifuge. Lokhu kufaka phakathi isivinini se-centrifuge nesikhathi, izinga lokushisa, uhlobo lwe-rotor kanye nosayizi, ivolumu yesampula, kanye nokukhetha indlela yokuhlukanisa. Ukwenza ngcono lezi ziguquguquko kubalulekile ekufinyeleleni imiphumela yokuhlukanisa enembile nehambisanayo.

Ukusetshenziswa kwe-Centrifugation Ezindaweni Ezihlukahlukene

I-Centrifugation inezinhlobo eziningi zezicelo emikhakheni ehlukene. Emalabhorethri ezokwelapha, isetshenziselwa ukuhlukaniswa kwesampula yegazi, okuvumela ukuhlukaniswa kwe-plasma noma i-serum ngezinjongo zokuxilonga. Embonini yezemithi, i-centrifugation isiza ezinqubweni zokuhlanza, ihlukanise izithako ezisebenzayo nokungcola. Ucwaningo lwezemvelo lusebenzisa i-centrifugation ukuhlaziya amasampula endle, okuvumela ukuhlonza ukungcola kanye nama-microorganism.

Ekuphetheni, i-centrifugation idlala indima ebalulekile ezinqubweni zokuhlukanisa, inikeza ithuluzi elinamandla kubacwaningi kanye nezimboni kuzo zonke imikhakha ehlukahlukene. Ukuqonda izimiso, izinhlobo, kanye nezindlela ze-centrifugation, kanye nokwenza ngcono izici ezibalulekile, kungaholela ekuhlukaniseni okuphumelelayo futhi kuveze imiphumela enembile. Ngokusebenzisa amandla e-centrifugation, ososayensi bayaqhubeka nokuvula amathuba amasha emkhakheni wesayensi yokuhlukanisa.
