i-centrifuge ihlukanisa kanjani izingxube

Ama-Centrifuge: Ukwembula Izimfihlo Zokuhlukaniswa Kwengxube

Isingeniso:

Ama-Centrifuge angamathuluzi anamandla asetshenziswa ezinhlotsheni ezahlukene zesayensi nezimboni ukuhlukanisa izingxube eziyinkimbinkimbi zibe izingxenye zazo ngazinye. Lawa madivayisi amangalisayo asebenzisa izimiso zamandla e-centrifugal ukuze kufezwe ukuhlukaniswa okunembile, okunikeza abacwaningi nochwepheshe ulwazi olubalulekile ngezinto eziningi ezahlukene. Kulesi sihloko, sizohlola ukuthi ama-centrifuge ahlukanisa kanjani izingxube, ukusetshenziswa kwazo emikhakheni ehlukene, kanye nezindlela eziyisisekelo ezenza ziphumelele kangaka.

I. Ukuqonda Amandla Aphakathi:

Ukuze siqonde ukuthi ama-centrifuge asebenza kanjani, kumele siqale sihlolisise umqondo wamandla e-centrifugal. Uma into ijikeleza i-axis ephakathi, njenge-spinning top noma i-merry-go-round, ihlangabezana namandla adonsela ngaphandle aziwa ngokuthi amandla e-centrifugal. La mandla avame ukusunduza izinto kude nesikhungo sokujikeleza.

II. Ukusebenzisa Amandla E-Centrifugal Ekuhlukaniseni:

Ama-Centrifuge asebenzisa la mandla e-centrifugal ukuhlukanisa izingxube ngokusekelwe ekubuneni okuhlukahlukene kwezingxenye zawo. Ngokujikeleza ngesivinini esikhulu, i-centrifuge idala insimu ye-centrifugal ekhiqiza amandla angaphandle anamandla. La mandla abangela ukuthi izinhlayiya noma izinto ezihlanganisiwe zibe nzima kakhulu ziye emaphethelweni angaphandle, kuyilapho izingxenye ezilula zihlala ziseduze nesikhungo.

III. I-Centrifugation ye-Density Gradient:

I-centrifugation ye-density gradient iyindlela esetshenziswa kabanzi ukuhlukanisa izingxube eziyinkimbinkimbi eziqukethe izinhlayiya noma izinto ezinobukhulu obuhlukene. Kule ndlela, kudalwa i-density gradient ngaphakathi kwe-centrifuge tube. Ngokubeka ngokucophelela izixazululo zobukhulu obuhlukahlukene, kwakheka i-gradient, lapho ubukhulu obuphezulu buphansi kanti obuphansi buphezulu.

IV. Ukuthuthwa kwendle kanye nokususwa kwendle:

Njengoba ingxube ifakwa eshubhini le-centrifuge futhi iphothwa ngesivinini esikhulu, izinhlayiya noma izinto ziyahamba nge-density gradient. Ngokuhamba kwesikhathi, izingxenye ezixineneyo zizochitheka bese zakha ibhande noma i-pellet ebonakalayo ebonakalayo phansi kweshubhi. Izingxenye ezingaxinene kakhulu zizohlala zilenga ezindaweni ezahlukene eceleni kwe-density gradient.

V. Izindlela Zokucisha Ugesi Ezisetshenziswayo Ezihlukahlukene:

I-Centrifugation isetshenziswa ezimbonini nasezindaweni eziningi ezahlukene, okuhlanganisa i-biology, i-chemistry, ukunakekelwa kwempilo, nokuningi. Ake sihlole izindlela ezimbalwa ezibalulekile kanye nokusetshenziswa kwazo.

A. I-Centrifugation Ehlukile:

I-differential centrifugation iyindlela esetshenziswa kabanzi ku-biology kanye ne-biochemistry. Ihilela uchungechunge lwezinyathelo ze-centrifugation ngesivinini esihlukene kanye nobude besikhathi ukuze kuhlukaniswe izinhlayiya ngokulandelana ngokusekelwe kusayizi wazo kanye nobuningi bazo. Le ndlela ivumela ukuhlukaniswa kwama-organelle eseli, njenge-mitochondria noma ama-lysosome, ezingxubeni eziyinkimbinkimbi njengezicubu ezihlanganayo.

B. I-Isopycnic Centrifugation:

I-Isopycnic centrifugation, eyaziwa nangokuthi i-density gradient centrifugation ngaphandle kwesinyathelo sokuhlushwa, isetshenziswa ekuhlukaniseni i-DNA, i-RNA, amagciwane, kanye nezinhlayiya ezingaphansi kweseli. Le ndlela yenza kube lula ukuhlukaniswa kwama-nucleic acid athile noma izinhlayiya ezibangelwa amagciwane ngokusekelwe ekubuthweni kwazo, okungukuthi, ubuningi bazo uma kuqhathaniswa nendawo ezungezile.

C. Ukulungiselela i-Ultracentrifugation:

I-preparative ultracentrifugation iyindlela enamandla esetshenziswa ekuhlanzeni nasekuhlukaniseni inani elikhulu lama-macromolecule ezinto eziphilayo, njengeprotheni nama-nucleic acid. Ngokubeka ingxube esivivinyweni esiphezulu sokujikeleza, ukuhlukaniswa kufezwa ngokusekelwe ekwehlukeni kwesisindo sama-molecule. Le ndlela idlala indima ebalulekile ekutadisheni nasekuqondeni isakhiwo nomsebenzi wama-biomolecule.

D. Isivinini Sokuthuthwa Kwendle:

I-sedimentation velocity centrifugation isetshenziswa ukuhlaziya ukusatshalaliswa kosayizi kanye nesisindo sama-molecule sama-macromolecule kusampula. Ngokuhlaziya ijubane le-sedimentation lezinhlayiya ezibhekene namandla amakhulu kakhulu, abacwaningi bangathola ukuqonda okubalulekile ngobukhulu, ukuma, kanye nezici zokusabalalisa zezingxenye eziyinhloko.

E. Ukuhlaziya i-Ultracentrifugation:

I-analytical ultracentrifugation inikeza inqubo enamandla yokufunda ukusebenzisana kwama-macromolecule, ukuchaza ukufana kokubopha, kanye nokunquma i-stoichiometry yezingxube eziyinkimbinkimbi. Ngokuhlaziya izakhiwo ze-sedimentation kanye nokusabalala kwezinhlayiya ngaphansi kwamandla e-ultracentrifugal, abacwaningi bangachaza ubunzima bokusebenzisana kwama-molecule.

Isiphetho:

Ama-centrifuge ayithuluzi elibalulekile ocwaningweni lwesayensi kanye nasembonini, okuvumela ukuhlukaniswa okunembile kwezingxube eziyinkimbinkimbi. Ngokusebenzisa amandla amandla e-centrifugal nokusebenzisa amasu ahlukahlukene, enza kube lula ukuhlukaniswa nokuhlaziywa kwezingxenye ezahlukahlukene ngokusekelwe ekubuneni kwazo, usayizi, kanye nobuningi obuhambayo. Ngokusebenzisa kwawo kabanzi emikhakheni eminingi, ama-centrifuge ayaqhubeka nokudlala indima ebalulekile ekuthuthukiseni ukuqonda kwethu umhlaba wemvelo kanye nokuthuthukisa izinqubo ezahlukene zobuchwepheshe.
