Izinto Ezihlukanisiwe Kusetshenziswa I-Centrifuge: Indlu Enamandla Yokuhlukanisa Ngokunembile

Isingeniso ku-Centrifugation kanye nezicelo zayo

I-Centrifugation iyindlela esetshenziswa kabanzi ezinqubweni ezahlukene zesayensi nezimboni ukuhlukanisa izinto ngokusekelwe ekubuneni kwazo nobukhulu bazo. Le ndlela enamandla incike ekusetshenzisweni kwamandla e-centrifugal, akhiqizwa ngokujikeleza isampula ngesivinini esikhulu, ukuze kufezwe ukuhlukaniswa okuphumelelayo. Kusukela kumasampula ebhayoloji emalabhorethri kuya ekukhiqizweni kwemikhiqizo ehlukahlukene ezimbonini, ama-centrifuge athola izinhlelo zokusebenza emikhakheni ehlukahlukene. Kulesi sihloko, sizohlola izinhlobo zezinto ezingahlukaniswa kusetshenziswa i-centrifuge kanye nokubaluleka kwazo emikhakheni ehlukene.

Ukuhlukanisa Amaseli Nezinhlayiya

Enye yezindlela eziyinhloko zokusebenzisa i-centrifugation ukuhlukaniswa kwamaseli nezinhlayiya. Ngokusebenzisa umehluko ngobukhulu nobuningi, i-centrifugation ivumela ukuhlukaniswa kwezingxenye ezithile kumasampula ayinkimbinkimbi. Isibonelo, emalabhorethri ezokwelapha, ama-centrifuge asetshenziswa kabanzi ukuhlukanisa nokufunda amaseli egazi. Lapho isampula yegazi ijikeleziswa ku-centrifuge ngesivinini esikhulu, amaseli abomvu egazi asindayo ahlala phansi kuyilapho i-plasma elula ihlala phezulu, okwenza kube lula ukuhlaziya okwengeziwe.

Ngokufanayo, ocwaningweni lwe-microbiology, i-centrifugation idlala indima ebalulekile ekutholeni amasiko ahlanzekile amabhaktheriya nemvubelo. Ngokulawula ngokucophelela ijubane kanye nobude be-centrifugation, lawa ma-microorganism angahlukaniswa nemidiya ezungezile, kusize ekutadisheni izici zawo, imetabolism, kanye namaphethini okukhula.

Ukuhlukaniswa Okunembile kwe-DNA ne-RNA

Ukuhlanganisa i-centrifugation kubalulekile ekuhlukaniseni ama-nucleic acid, njenge-DNA ne-RNA, kumasampula ebhayoloji. Lezi zinto zofuzo zivame ukudinga ukukhishwa ngendlela yazo emsulwa kakhulu ukuze kusetshenziswe izinhlelo ezahlukene, okuhlanganisa ucwaningo lwezakhi zofuzo kanye nezinjongo zokuxilonga. Amasu okuhlanganisa i-centrifugation, njenge-density gradient centrifugation, avumela ukuhlukaniswa kwama-nucleic acid kwezinye izingxenye zamaseli, njengeprotheni nama-lipid.

Le nqubo ihilela ukulayisha isampula yezinto eziphilayo endaweni yokulinganisa ubuningi, ngokuvamile isixazululo se-sucrose noma se-cesium chloride, bese sisetshenziswa nge-centrifuge kusetshenziswa isivinini esikhulu. Ngesikhathi sokulinganisa ubuningi, ama-nucleic acid ahamba nge-density gradient aze afike endaweni enobuningi obuthile obufana nobawo. Le ndlela yokuhlukanisa ngokunemba ivumela ukukhishwa kwe-DNA emsulwa ne-RNA yezinhlelo zokusebenza ezingezansi njenge-PCR, ukulandelana kofuzo, kanye nokuhlaziywa kokubonakaliswa kofuzo.

Ukuhlanza ama-Biomolecule

Ukuhlanganisa i-centrifugation kubalulekile ekuhlanzeni ama-biomolecule ahlukahlukene, okuhlanganisa amaprotheni nama-enzyme. Ema-laboratories e-biochemistry kanye ne-biotechnology, izinhlobo ezahlukene zama-centrifuge ziyasetshenziswa ukuhlukanisa nokuhlanza la ma-molecule ayinkimbinkimbi. Ngokusebenzisa izakhiwo zawo ezihlukile, njengosayizi, ukuma, kanye nobuningi, amasu okuhlanganisa i-centrifugation asusa ngempumelelo ukungcola futhi agxilise i-biomolecule efiselekayo.

I-Ultracentrifugation, inqubo enamandla esebenzisa isivinini esikhulu kakhulu, ivame ukusetshenziselwa ukuhlanza nokuhlukanisa amaprotheni. Kule nqubo, amasampula abhekana namandla anamandla aphindwe izikhathi eziningana kunomhubhe woMhlaba, okuholela ekuhlukanisweni okunembile kwezingxenye ezahlukene zamaprotheni. Lokhu kuvumela abacwaningi ukuthi bahlukanise amaprotheni athile noma ama-protein complexes athakazelisayo, okwenza kube lula ukufunda ngokujulile izakhiwo zawo zama-molecule kanye nemisebenzi yawo.

Izicelo Zezimboni Zoku-Centrifugation

Ngaphandle kocwaningo lwesayensi, i-centrifuge idlala indima ebalulekile ezinqubweni eziningi zezimboni. Embonini yokudla neziphuzo, ama-centrifuge asetshenziselwa ukuhlukanisa izinto eziqinile koketshezi, ukugxila amajusi ezithelo, ukucacisa iwayini, kanye namafutha acwebezelayo, phakathi kwezinye izinhlelo zokusebenza. Ngokususa ukungcola, njengezinto eziqinile, izinhlayiya ezilengayo, noma amaseli angafuneki e-microbial, ama-centrifuge asiza ukuthuthukisa ikhwalithi yomkhiqizo futhi andise isivuno.

Imboni yezemithi iphinde ithembele kakhulu ekufakweni kwe-centrifuge ukuze kuhlukaniswe futhi kuhlanzwe izinqubo ngesikhathi sokukhiqizwa kwemithi kanye nemijovo. Ama-centrifuge asetshenziswa ekukhishweni kwezithako ezisebenzayo ezitshalweni, ekuvuneni amaseli, ekuhlanzweni kwamaprotheni, nasekukhiqizweni kwemijovo.

Isiphetho:

I-Centrifugation iyindlela ehlukahlukene ehlinzeka ngokuhlukaniswa okunembile kwezinto ezahlukahlukene ngokusekelwe ekubuneni kwazo nobukhulu bazo. Kusukela ekuhlukaniseni izingxenye zegazi ezindaweni zokucwaninga zezokwelapha kuya ekuhlukaniseni amaprotheni okucwaninga nokuhlanza amakhemikhali emithi, ama-centrifuge angamathuluzi abalulekile ezinhlotsheni eziningi zezicelo. Njengoba ubuchwepheshe buthuthuka, izindlela ze-centrifugation ziyaqhubeka nokukhula futhi zinegalelo ekuthuthukisweni emikhakheni eminingi yesayensi, yezimboni kanye neyezokwelapha.
