Ukusetshenziswa kwama-Centrifuge eLaboratories
I-centrifuge iyithuluzi elibalulekile emalabhorethri ahlukahlukene, kusukela emalabhorethri emitholampilo kanye naselabhorethri yebhayoloji kuya emalabhorethri amakhemikhali, kanye nasezimbonini zemithi nezokudla. Isebenza ngesimiso samandla e-centrifugal, amandla akhiqizwa ukujikeleza okusheshayo okuhlukanisa izinhlayiya zesampula ngokusekelwe ekwehlukeni kobuningi nosayizi. Ngamakhono ayo okuhlukanisa okusheshayo nokunembile, ama-centrifuge anikela ekusebenzeni kahle kwezinqubo eziningi zokuhlaziya, zocwaningo, kanye nezokukhiqiza. Lesi sihloko sixoxa ngokusetshenziswa kwama-centrifuge emalabhorethri, izinhlobo zawo, kanye nezibonelo zokusetshenziswa kwawo.
Isimiso Sokusebenza Esifushane Se-Centrifuge
Empeleni, i-centrifuge ijikeleza isampula epayipini ngesivinini esikhulu. Njengoba ijikeleza, izingxenye ezisindayo ziyakhishwa (zibheke phansi kwepayipi), kuyilapho izingxenye ezilula zihlala phezulu. Ukuhlukaniswa okubangelwayo kuvame ukwakha izingxenye ezimbili: i-sediment (i-pellet) phansi kanye ne-supernatant phezulu. Ukuqinisekisa ukuhlukaniswa okuhle kakhulu, opharetha kudingeka anake amapharamitha amaningana, njengejubane lokujikeleza (i-RPM noma i-RCF), isikhathi, izinga lokushisa, kanye nohlobo lwe-rotor esetshenziswayo.
Ukusetshenziswa kwama-Centrifuge eLaboratories
1. Ukuhlukanisa Izingxenye Zegazi Elabhorethri Yezokwelapha
Enye yezindlela ezivame kakhulu zokusebenzisa i-centrifuge ukuhlolwa kwegazi. Isampula yegazi ngokuvamile ihlanganisa i-plasma/serum, amaseli abomvu egazi, amaseli amhlophe egazi, nama-platelet. I-centrifugation ivumela izingxenye zegazi ukuthi zihlukaniswe ngezinjongo ezahlukene zokuhlola, njenge:
- Ukulungiswa kwe-serum ukuze kuhlolwe amakhemikhali emitholampilo njengokuhlola i-glucose, i-cholesterol, ama-enzyme esibindi kanye namazinga e-electrolyte.
– Ukuhlukaniswa kwe-plasma ukuze kuhlolwe ukujiya kwegazi (ukujiya kwegazi) noma ukuhlaziywa okuthile okudinga i-plasma.
– Ukuhlukaniswa kwe-buffy coat (ungqimba oluncane oluqukethe ama-leukocyte nama-platelet) ukuze kuhlolwe igazi noma kuhlaziywe okwengeziwe.
Ngaphandle kwe-centrifuge, inqubo yokuhlukanisa ingathatha isikhathi eside futhi imiphumela izoba engaguquguquki.
2. Ukuhlukanisa Nokuhlanza i-DNA, i-RNA, kanye neProtheyini
Emalabhorethri ebhayoloji yama-molecular, i-centrifuge iyithuluzi elisetshenziswa cishe emhlabeni wonke. Ukukhishwa kwe-DNA/RNA kanye nezinqubo zokuhlanza amaprotheni ngokuvamile kuhilela izinyathelo eziningana ze-centrifuge ukuze:
– Izingcezu zamaseli eziwa noma ama-nuclei eseli.
– Ukuhlukanisa isigaba soketshezi ekukhishweni (isb. ukuhlukanisa izinto ezisindayo eziqukethe ama-nucleic acid).
– Ukuqoqa i-DNA/RNA/protein ngesimo se-pellet ngemuva kokufaka utshwala noma ama-reagent athile.
– Ukugeza ama-pellets usebenzisa i-buffer ukuze kwandiswe ubumsulwa.
Ama-microcentrifuge avame ukusetshenziswa kumashubhu amancane (isb. 1,5–2 mL) ezinqubweni zocwaningo lwezakhi zofuzo, i-PCR, ukulandelana, kanye nokuhlaziywa kokubonakaliswa kwezakhi zofuzo.
3. Ukuhlukanisa Amaseli kanye nezinhlayiya emasikweni e-Microbiological
Ku-microbiology, i-centrifuge isetshenziswa ukuqoqa amaseli ebhaktheriya noma emvubelo kusuka ku-liquid media. Ukusetshenziswa kwayo kufaka phakathi:
– Gxilisa ama-microorganism ngaphambi kokuhlolwa kwe-microscopic noma ukuhlolwa kwe-biochemical.
– Ukukhipha i-biomass ukuze kukhishwe i-DNA, iphrotheni, noma i-metabolite.
– Geza amaseli ngesisombululo se-buffer ukuze ususe noma yikuphi okusele okungase kuphazamise ukuhlolwa.
Ngokujikeleza okufanele, amangqamuzana amagciwane angaqoqwa abe ama-pellet ahlukaniswa kalula nezitho zangaphakathi.
4. Ukuhlukaniswa Kwezinsalela Ekuhlaziyweni Kwamakhemikhali
Emalabhorethri e-analytical chemistry, ama-centrifuge awusizo kakhulu ekusheshiseni ukuhlukaniswa kwama-precipitate nezixazululo. Kwezinye izivivinyo, kwakheka ama-precipitate, okumele asuswe ngaphambi kokuhlunga noma ukulinganisa okwengeziwe. Ama-Centrifuge angenza lokhu:
– Kunciphisa isidingo sokuhlunga isikhathi eside.
– Thola i-supernatant ecacile yokuhlaziya i-spectrophotometric noma i-titration.
– Ihlukanisa izinhlayiya ezincane okunzima ukuzihlunga ngephepha lokuhlunga elijwayelekile.
Lokhu kubaluleke kakhulu uma amasampula emancane noma lapho kudingeka imiphumela esheshayo.
5. Ukuhlolwa Kwekhwalithi Embonini Yezemithi Nokudla
Ngaphezu kocwaningo kanye nokusetshenziswa kwezokwelapha, ama-centrifuge asetshenziswa kabanzi ekulawuleni ikhwalithi (QC). Embonini yezemithi, ama-centrifuge angasetshenziswa ku:
– Ukuhlola ukuqina kokumiswa noma i-emulsion.
- Ukuhlolwa kokuhlukaniswa kwesigaba okungenzeka emikhiqizweni yoketshezi.
– Kusiza ekuhlanzweni kwezithako ezisebenzayo noma ekuhlukanisweni kwenhlabathi ezinqubweni zokukhiqiza ezincane.
Embonini yokudla, ama-centrifuge awusizo ekuhlukaniseni amafutha, indle, noma izinhlayiya emikhiqizweni ewuketshezi, isibonelo ekucubungulweni kobisi, iziphuzo, noma okukhishwe ekudleni.
6. Ukuhlukaniswa Okusekelwe Kubuningi (Ubukhulu Be-Density Gradient Centrifugation)
Ukuze kusetshenziswe ngendlela eyinkimbinkimbi kakhulu, i-centrifuge ingasetshenziswa ngendlela ye-density gradient, esebenzisa izixazululo ezinobukhulu obuhlukahlukene (isb., i-sucrose noma i-cesium chloride). Le ndlela iwusizo ku:
– Ukuhlukanisa ama-organelle eseli njenge-mitochondria, i-nucleus, kanye ne-lysosomes.
– Ihlukanisa izinhlayiya zegciwane.
– Hlanza i-DNA ye-plasmid noma izingcezu ezithile zezinto eziphilayo.
Le ndlela ivame ukusetshenziswa ocwaningweni lwezokwelapha ngoba iyakwazi ukukhiqiza ukuhlukaniswa okuqondile kakhulu kune-centrifugation evamile.
7. Sheshisa Inqubo Yokuthuthwa Kwendle Kumaphrothokholi Ahlukahlukene
Izinqubo eziningi zelebhu ngokwemvelo zidinga ukuhlaliswa kwemvelo (ukususwa kwenhlabathi), kodwa ukususwa kwenhlabathi kwemvelo kuvame ukuba kancane. I-centrifuge isheshisa le nqubo, inciphise isikhathi somsebenzi futhi ikhulise umkhiqizo. Leli thuluzi linikeza izinzuzo ezinkulu zokusebenza kahle, ikakhulukazi emalabhorethri anesampula ephezulu.
Izinhlobo Ezivame Ukusetshenziswa Zama-Centrifuge
Ilabhorethri ngayinye ingasebenzisa i-centrifuge ehlukile ngokwezidingo zayo:
1. I-centrifuge yezokwelapha: ivame ukusetshenziselwa ukuhlukanisa i-serum/i-plasma egazini.
2. I-Microcentrifuge: yamapayipi amancane, avamile ku-biology yama-molecule.
3. I-centrifuge efrijini: ifakwe isibandisi samasampula azwela ukushisa njengamaphrotheni noma ama-enzyme.
4. I-centrifuge enesivinini esikhulu: yokuhlukanisa kahle kanye nesivinini esikhulu.
5. I-Ultracentrifuge: yokuhlukanisa izinhlayiya ezincane kakhulu ezifana namagciwane, ama-ribosome, noma ama-lipoprotein.
Ukukhetha uhlobo lwe-centrifuge kuncike ezidingweni zesivinini, umthamo wepayipi, kanye nokuqina kwesampula.
Izinto Ezibalulekile Ekusebenziseni I-Centrifuge: Ukuphepha Nokunemba
Nakuba kuwusizo, ama-centrifuge nawo adala izingozi ezingaba khona uma esetshenziswa ngendlela engafanele. Ezinye izinto okufanele uzicabangele zifaka:
– Ukulinganisa ithubhu: ithubhu kumele libe nobunzima obulinganayo ukuze i-rotor ingadlidlizi futhi ivimbele umonakalo ethuluzini noma ezingozini.
– Ukusebenzisa amashubhu afanele: izinto zeshubhu kumele zimelane nesivinini esithile kanye nama-reagent.
– Vala i-rotor kahle: ukuvimbela ukuvuza noma ama-aerosol.
– Landela imikhawulo ye-RPM/RCF: ngoba i-rotor ngayinye inomkhawulo ophephile.
– Ukuhlanza okuchithekile: Amasampula ebhayoloji achithekile angaba yingozi futhi kumele aphathwe ngokwezinqubo zokuphepha kwebhayoloji.
Ukusetshenziswa ngokucophelela akugcini nje ngokuqinisekisa ukuphepha, kodwa futhi kuqinisekisa imiphumela yokuhlukaniswa enembile nehambisanayo.
Isiphetho
Ukusetshenziswa kwama-centrifuge emalabhorethri kubanzi futhi kuyisisekelo, ikakhulukazi ekuhlukaniseni izingxenye kumasampula ngokusekelwe ekuhlukeni kobuningi nosayizi. Kusukela ekuhlukanisweni kwegazi emalabhorethri emitholampilo, ukuhlukaniswa kwe-DNA/RNA ku-molecular biology, ukuqoqwa kwamaseli e-microbial, kuya ekuhlolweni kwekhwalithi embonini, ama-centrifuge asiza ukusheshisa izinqubo zomsebenzi futhi athuthukise ukunemba kokuhlaziya. Ngokukhetha okulungile kwe-centrifuge kanye nokusetshenziswa kwezinqubo zokuphepha ezifanele, la mathuluzi ayinsika yemisebenzi eminingi yelabhorethri yanamuhla.
Uma uthanda, ngingangeza nesigaba esithi “indlela yokufunda i-RCF vs RPM” noma isibonelo esilula sokubala ukuze sisebenze kakhulu emibikweni yelebhu.
