uhlobo luni lwezingxube ezihlukaniswa yi-centrifugation

I-Centrifugation: Ukuhlukanisa Izingxube Ezihlukahlukene Ngokusekelwe Ekwehlukeni Kobuningi

Isingeniso:

I-Centrifugation iyindlela enamandla yelabhorethri esetshenziselwa ukuhlukanisa izingxube ngokusekelwe ekuhlukeni kwazo kobuningi. Ngokufaka ingxube ekujikelezeni okusheshayo, i-centrifugation isebenzisa izimiso zamandla adonsela phansi ukuze kufezwe ukuhlukana. Le ndlela ithola ukusetshenziswa okubanzi emikhakheni ehlukahlukene, kufaka phakathi i-biology, i-chemistry, imithi, kanye neminye eminingi. Kulesi sihloko, sizohlola izinhlobo ezahlukene zezingxube ezingahlukaniswa ngempumelelo nge-centrifugation, kanye nokusetshenziswa kwazo.

1. Ukuhlukaniswa Kwezingxenye Zegazi:

Enye yezindlela ezivame kakhulu zokusebenzisa i-centrifugation ukuhlukaniswa kwezingxenye zegazi. Igazi eliphelele lakhiwe izingxenye ezahlukene zamaseli kanye noketshezi, ngayinye inobukhulu obuhlukile. Ngokujikelezisa isampula yegazi ku-centrifuge, lezi zingxenye zingahlukaniswa zibe izendlalelo ezihlukene. Izingxenye ezisindayo, njengamaseli abomvu egazi, zihlala phansi, kuyilapho lezo ezilula, njenge-plasma noma i-serum, zihlala phezulu.

Ukwehlukanisa igazi nge-centrifugation kusiza ekuhlukaniseni izingxenye zegazi ngezinjongo zokuxilonga, njengokunquma amazinga e-hematocrit noma ukuhlukanisa amangqamuzana athile afana nama-platelet noma amangqamuzana amhlophe egazi ukuze kuhlaziywe kabanzi. Ngaphezu kwalokho, ukwehlukanisa igazi nge-centrifugation kudlala indima ebalulekile ekugcinweni kwegazi, okuvumela ukuhlukaniswa kwegazi libe izingxenye ezahlukene ngezinjongo zokumpontshelwa igazi.

2. Ukuhlanzwa kwe-DNA ne-RNA:

Amasu okukhipha i-DNA ne-RNA athembele kakhulu ekuhlanganiseni i-centrifugation ukuze kuhlanzwe kahle. Ngesikhathi senqubo yokukhipha, amasampula ebhayoloji avame ukuqukatha ukungcola, njengeprotheni, amafutha, noma ezinye izinsalela zamaseli, okungaphazamisa ukuhlaziywa kwezakhi zofuzo okulandelayo. Ukuxubha i-centrifugation kusiza ukuhlukanisa i-DNA noma i-RNA kulezi zingcolisi, okuholela ezintweni zofuzo ezihlanzwe kakhulu.

Izindlela ezahlukene zokuhlukanisa, njenge-differential centrifugation kanye ne-isopycnic density gradient centrifugation, zisetshenziswa ukuhlukanisa i-DNA noma i-RNA ngokusekelwe ekujuleni kwayo. Le nqubo yokuhlanza ibalulekile ekusetshenzisweni okufana nokulandelana kwezakhi zofuzo, i-PCR (polymerase chain reaction), kanye ne-DNA fingerprinting, njengoba iqinisekisa imiphumela enembile nethembekile.

3. Ukuhlukaniswa Kwezinto Eziyizingxenye Ekuhlaziyweni Kwemvelo:

I-Centrifugation ithola nokusetshenziswa kwayo ekuhlaziyweni kwemvelo, ikakhulukazi ekuhlukaniseni nasekuhlaziyweni kwezinto ezincane. Amasampula ezemvelo, njenge-sediment noma inhlabathi, angase aqukathe izinhlobo ezahlukene zezinhlayiya eziphilayo nezingaphili ezinobukhulu obuhlukahlukene. Ngokufaka la masampula ku-centrifugation, abahlaziyi bangahlukanisa izingxenye ezahlukene ngokusekelwe emazingeni azo okugcwala.

Le ndlela yokuhlukanisa ibalulekile ekutadisheni ukungcola kwemvelo, ukuhlonza izinsimbi ezisindayo, noma ukuhlaziya ukusatshalaliswa kwezinhlayiya emasampuleni omoya noma amanzi. I-Centrifugation isiza ekuhlukaniseni izingxenyana ezithile zezinto ezincane, okuvumela ukuhlaziywa okunembile kanye namasu okunciphisa okulandelayo.

4. Ukuhlukaniswa kwama-Organelle angaphansi kwamangqamuzana:

I-Centrifugation iyindlela ebalulekile yokufunda izakhiwo zamaseli nemisebenzi yazo. Ngokusebenzisa i-differential centrifugation noma i-density gradient centrifugation, abacwaningi bangahlukanisa ama-organelle athile angaphansi kweseli, abalulekile ekuqondeni izinqubo zamaseli.

Isibonelo, i-mitochondria, izindawo zamandla zeseli, ingathuthukiswa futhi ihlukaniswe nezinye izingxenye zeseli ngokusebenzisa i-ultracentrifugation. Ngokufanayo, ezinye i-organelles njenge-lysosomes, i-peroxisomes, noma i-endoplasmic reticulum zingahlukaniswa nge-differential centrifugation ngesivinini nobude obuhlukahlukene.

5. Ukuhlanzwa Kwezinhlayiya Zegciwane:

I-Centrifugation idlala indima ebalulekile ku-virology, ikakhulukazi ekuhlanzweni kwezinhlayiya zegciwane. Ama-virus aziwa ngobukhulu bawo obuncane kanye nobunzima bawo, okwenza ukuhlukaniswa kwawo kube umsebenzi onzima. Kodwa-ke, ngokusebenzisa amasu e-centrifugation asheshayo njenge-ultracentrifugation, abacwaningi bangahlukanisa izinhlayiya zegciwane kumaseli abanjwe kanye nezinye izinto ezingcolisayo.

Le nqubo yokuhlanza isiza ekuqondeni isakhiwo segciwane, ukuphenya ukutheleleka ngegciwane, kanye nokuthuthukisa imigomo. Ukuhlukaniswa nge-centrifugation kusiza nasekulinganisweni kwegciwane futhi kuvumela ukuhlaziywa okwengeziwe, okuhlanganisa i-electron microscopy noma ukuchazwa kwama-molecule.

Isiphetho:

I-Centrifugation iyindlela eguquguqukayo evumela ukuhlukaniswa kwezingxube ezahlukahlukene ngokusekelwe ekuhlukeni kwazo kobuningi. Ukusetshenziswa kwayo kufinyelela kude, kusukela ekuxilongweni kwezokwelapha kanye nokuhlaziywa kwezakhi zofuzo kuya ocwaningweni lwezemvelo kanye ne-virology. Ngokusebenzisa izimiso zamandla adonsela phansi kanye nokujikeleza okusheshayo, i-centrifugation iyaqhubeka nokuba ithuluzi elibalulekile emizamweni eminingi yesayensi.
