yimiphi imingcele yokuhlukaniswa kanye nokuhlukaniswa nge-centrifugation

Iyini Imingcele Yokuhlukaniswa Nokuhlukaniswa Nge-Centrifugation?

Isingeniso:

I-Centrifugation iyindlela esetshenziswa kabanzi elabhorethri yokuhlukanisa nokuhlukaniswa kwezingxenye ezahlukene zengxube ngokusekelwe ekubuneni kwazo kusetshenziswa isimiso se-sedimentation. Ihilela ukujikeleza okusheshayo kwesampula ngesivinini esikhulu, okuvumela izinhlayiya eziqinile noma izingxenye ukuthi zihlale phansi kuyilapho izinhlayiya ezilula zihlala phezulu. Nakuba i-centrifugation iyithuluzi elinamandla, inemikhawulo yayo. Kulesi sihloko, sizohlola imikhawulo yokuhlukaniswa nokuhlukaniswa nge-centrifugation, siqokomise ezinye zezinselele ezibalulekile abacwaningi ababhekana nazo lapho besebenzisa le ndlela.

1. Usayizi Wezinhlayiyana Nobuningi:

Esinye sezici ezibaluleke kakhulu ezinquma impumelelo yokuhlukaniswa kanye nokuhlukaniswa nge-centrifugation usayizi wezinhlayiya kanye nobuningi. I-centrifugation isebenza kahle kakhulu ekuhlukaniseni izinhlayiya ngomehluko omkhulu ekuxineni, njenge-organelles, ama-macromolecule, noma udoti weseli. Kodwa-ke, lapho izinhlayiya noma izingxenye zinobukhulu noma ubukhulu obufanayo, ukuhlukaniswa okufanele kuba yinselele. Amandla e-centrifugal angase anganeli ukufeza ukuhlukaniswa okuphelele, okuholela ekuhlanganiseni amabhande noma ukuhlukaniswa okungaphelele.

2. Ukuhlanganisa inhlabathi:

I-co-sementation ibhekisela enkingeni yezingxenye ezithile noma izinhlayiya ezihlangana ndawonye ngesikhathi se-centrifugation, okwenza kube nzima ukuzihlukanisa ngokuphelele. Lesi simo senzeka lapho umehluko wobuningi phakathi kwezingxenye uncane kakhulu, okuholela ekufudukeni ndawonye ngesikhathi se-centrifugation. I-co-sementation ingaba yinkinga ikakhulukazi lapho usebenza ngezingxube eziyinkimbinkimbi, njengezibonelo zezinto eziphilayo noma ama-macromolecular complexes, lapho ukuhlukaniswa kwezingxenye ezithile kuyinselele ngenxa yezici zazo ezifanayo.

3. Isampula Yokungcola:

Ngesikhathi sokufaka i-centrifugation, ukungcola kwesampula kungaba yinselele enkulu. Kubalulekile ukuqinisekisa ukuthi izimo ze-centrifugation kanye nemingcele zilungiselelwe ukunciphisa ukungcola okuvela kuma-rotor, amapayipi, noma amapayipi okuqoqa. Ukungcola kungaphazamisa inqubo yokuhlukaniswa, okuholela kumasampula angcolile. Kufanele kuqashelwe ngokucophelela ekukhetheni izinto ezifanele ze-rotor, ukusebenzisa amapayipi afanele okufaka i-centrifugation, kanye nokusebenzisa izindlela zokuhlanza ezisebenzayo ukuvimbela ukungcola kwesampula.

4. Isixazululo Esilinganiselwe:

Ukuxazululwa kokuhlukaniswa kanye nokuhlukaniswa nge-centrifugation kuncike kakhulu ekukhetheni i-centrifuge kanye ne-rotor. Amasu ahlukene e-centrifugation, njenge-differential centrifugation noma i-density gradient centrifugation, anikeza amazinga ahlukahlukene okuxazululwa. Ngenkathi i-density gradient centrifugation inikeza ukuhlukaniswa kwe-high resolution, idinga izinyathelo ezengeziwe kanye nemishini ekhethekile. I-differential centrifugation, nakuba ilula, ingaba ne-resolution elinganiselwe, okuholela kuma-band ahambisanayo kuma-fraction aphumayo. Abacwaningi kudingeka bacabangele ngokucophelela i-resolution efiselekayo yokusetshenziswa kwabo okukhethekile bese bekhetha indlela efanele ye-centrifugation ngokufanele.

5. Isikhathi Nezindleko:

Ukuhlanganisa i-centrifugation kungaba inqubo ethatha isikhathi futhi ebiza kakhulu. Ukufinyelela ukuhlukaniswa okuhle kakhulu kanye nokuhlukaniswa kungadinga izinyathelo eziningi, izikhathi ezinde zokuhlanganisa i-centrifugation, kanye namasu akhethekile. Isibonelo, ukuze bathole izingxenyana ezihlanzwe kakhulu, abacwaningi kungadingeka benze imijikelezo elandelanayo yokuhlanganisa i-centrifugation, okuholela ekwandeni kwesikhathi kanye nokutshalwa kwezimali kwezinsiza. Ngaphezu kwalokho, ama-rotor nama-centrifuge akhethekile akwazi ukuhlukaniswa ngesivinini esikhulu nangesisombululo esiphezulu kungabiza kakhulu ukuwathola nokuyinakekela, okwenza kubaluleke ukulinganisa izinzuzo ngokumelene nezindleko ezihambisanayo.

Isiphetho:

I-Centrifugation ishintshe kakhulu insimu yokuhlukaniswa kanye nokuhlukaniswa, okwenza abacwaningi bakwazi ukuthola izingxenye ezihlanziwe ezingxubeni eziyinkimbinkimbi. Kodwa-ke, nayo inemikhawulo yayo. Amabhande ahambisanayo, i-co-sedimentation, ukungcola kwesampula, ukulungiswa okulinganiselwe, kanye nesikhathi kanye nezici zezindleko ezihambisanayo konke kuyinselele ekusetshenzisweni ngempumelelo kwe-centrifugation. Naphezu kwale mikhawulo, i-centrifugation isalokhu kuyindlela ewusizo emikhakheni eminingi yesayensi, futhi intuthuko eqhubekayo ihlose ukunqoba lezi zinselele futhi ithuthukise ukusebenza kwayo kahle kanye nokusebenza kahle. Abacwaningi kumele bahlole ngokucophelela imikhawulo futhi bathuthukise izinqubo zabo ze-centrifugation ukuqinisekisa ukuhlukaniswa kanye nokuhlukaniswa okuphumelelayo kwezicelo zabo ezithile.
