Intshayelelo kwiCentrifugation: Indlela iCentrifuge eyahlula ngayo imixube
I-Centrifugation yindlela esetyenziswa kakhulu yelabhoratri esebenzisa imigaqo ye-sedimentation kunye ne-centrifugal force ukwahlula imixube ngokusekelwe kubuninzi bayo. Le nkqubo ibalulekile kwiindawo ezininzi zesayensi kunye nezonyango apho ukwahlulahlula izinto ezahlukeneyo kwisampulu kuyadingeka ukuze kuhlalutywe, kucocwe, okanye kuhlulwe. Kweli nqaku, siza kuxoxa ngemigaqo esisiseko ye-centrifugation kwaye sihlolisise ukusetyenziswa kunye neentlobo ezahlukeneyo ze-centrifuges ezisetyenziswa kumashishini ahlukeneyo.
1. Imigaqo yeCentrifugation
Ngaphambi kokuba sihlolisise ubunzima bokusebenzisa i-centrifugation, kubalulekile ukuqonda imigaqo esekwe kule ndlela. Umgaqo oyintloko ochaphazelekayo apha kukusetyenziswa kwamandla e-centrifugal ukwahlulahlula izinto zomxube. Xa isampuli ifakwa kwi-centrifuge kwaye ijikeleziswa ngesantya esiphezulu, amasuntswana axineneyo okanye iimolekyuli ziya ezantsi, ngelixa amasuntswana angaxineneyo ahlala kufutshane nephezulu. Oku kwahlulwa kwenzeka ngenxa yokutsalwa kwamasuntswana axineneyo, okukhawuleziswa ngamandla e-centrifugal.
2. Iintlobo ezahlukeneyo zeeCentrifuges
Kukho iintlobo ngeentlobo zee-centrifuge ezikhoyo, nganye yenzelwe ukusetyenziswa okuthile. Enye yezona ntlobo zisetyenziswa kakhulu yi-benchtop centrifuge, esebenziseka lula kwaye isetyenziswa kwiilabhoratri kwimisebenzi yokwahlulahlula rhoqo. Olunye uhlobo yi-ultracentrifuge, ekwaziyo ukufikelela kwisantya esiphezulu kakhulu kwaye ivelise amandla amakhulu e-centrifugal, okwenza ukuba ifaneleke kwimisebenzi efuna ukwahlukanisa amasuntswana anobunzima obuphantsi kakhulu.
Kwelinye icala, ii-centrifuge ezifakwe efrijini zixhotyiswe ngeenkqubo zokupholisa ezivumela ukwahlulwa kweesampuli ezinobungcipheko ngaphandle kokubeka emngciphekweni ukuthembeka kwazo. Ezi centrifuge zisetyenziswa kakhulu kwizicelo ezifana ne-molecular biology, apho ukugcina ubushushu obufanelekileyo kubalulekile.
3. Izicelo zeKlinikhi
Kwicandelo lokuxilongwa kwezonyango, i-centrifugation idlala indima ebalulekileyo ekuhlalutyweni nasekuhlukanisweni kweesampuli zegazi. Ngokujikelezisa iisampuli zegazi kwi-centrifuge, iingcali zonyango zinokwahlulahlula izinto ezahlukeneyo, ezifana neeseli ezibomvu zegazi, iiseli ezimhlophe zegazi, kunye ne-plasma. Olu kwahlulahlula luvumela ukufunyanwa nokuchongwa kwezifo ezahlukeneyo kunye neemeko, kunye nokuqokelelwa kwezinto ezithile zegazi ngeenjongo zonyango.
4. Izicelo zemizi-mveliso
I-Centrifugation ikwasetyenziswa kakhulu kwiinkqubo ezahlukeneyo zoshishino. Umzekelo, kwishishini lokutya neziselo, ii-centrifuge zisetyenziselwa ukwahlula ulwelo kwizinto eziqinileyo kunye nokucacisa iijusi, iwayini, kunye nezinye iziselo. Ukongeza, ii-centrifuge zidlala indima ebalulekileyo kwizityalo zonyango lwamanzi amdaka, apho zinceda ekwahlukaniseni izinto eziqinileyo emanzini, zivumela ukulahlwa okanye ukusetyenziswa kwakhona kwamanzi acociweyo ngokukhuselekileyo.
5. Uphando kunye neBiotechnology
Kwiilabhoratri zophando kunye nezibonelelo ze-biotechnology, i-centrifugation isetyenziswa kakhulu kwiindlela ezahlukeneyo zokusebenza. Isetyenziswa kakhulu ekucoceni iiproteni, ukwahlula ii-organelles zeeseli, ukwahlula ii-nucleic acids, kunye nokuqokelela iiseli kwi-cell culture media. Ezi nkqubo zibalulekile ekwenzeni iimvavanyo, ukufunda izinto ezithile zeeseli, kunye nokuphuhlisa izisombululo zonyango.
Isiphelo
I-Centrifugation yindlela ebaluleke kakhulu evumela ukwahlulwa kwemixube kwiindlela ezahlukeneyo zesayensi, zonyango, kunye nezoshishino. Ngokusebenzisa amandla amandla e-centrifugal, abaphandi kunye neengcali kwiinkalo ezahlukeneyo banokwahlulahlula kwaye bahlalutye izinto ezahlukeneyo ngaphakathi kwesampulu ngokuchanekileyo. Ukuguquguquka kunye noluhlu olubanzi lwezicelo ze-centrifugation kuyenza ibe sisixhobo esibalulekileyo kwiilabhoratri kwihlabathi liphela, inceda kwimisebenzi eqala kwiinkqubo zokuxilonga eziqhelekileyo ukuya kuphando oluphambili.
