Zithini iiMida zokuQhathwa kunye nokuHlulwa yiCentrifugation?

Intshayelelo:

I-Centrifugation yindlela esetyenziswa kakhulu kwilebhu yokwahlula nokuqhekeza iinxalenye ezahlukeneyo zomxube ngokusekelwe kubuninzi bazo kusetyenziswa umgaqo we-sedimentation. Ibandakanya ukujikeleza ngokukhawuleza kwesampuli ngesantya esiphezulu, okuvumela iinxalenye ezixineneyo okanye iinxalenye ukuba zihlale ezantsi ngelixa iinxalenye ezikhaphukhaphu zihlala phezulu. Nangona i-centrifugation isisixhobo esinamandla, inemida yayo. Kweli nqaku, siza kuhlola imida yokuqhekeza kunye nokwahlula nge-centrifugation, sigqamise eminye imingeni ephambili abaphandi abajongene nayo xa besebenzisa le ndlela.

1. Ubungakanani kunye nobuninzi beenxalenye:

Enye yezona zinto zibalulekileyo ezimisela impumelelo yokuqhekeka kunye nokwahlukana nge-centrifugation bubungakanani be-particle kunye noxinano. I-Centrifugation isebenza kakhulu ekuhlukaniseni amasuntswana anomahluko omkhulu kuxinano, njenge-organelles, i-macromolecules, okanye i-debris yeseli. Nangona kunjalo, xa amasuntswana okanye izinto zinobunzima okanye imilinganiselo efanayo, ukwahlukana okufanelekileyo kuba nzima. Amandla e-centrifugal asenokunganeli ukufezekisa ukwahlukana okupheleleyo, okukhokelela kwiibhendi ezigqithanayo okanye ukwahlukana okungaphelelanga.

2. Ukudibanisa inkunkuma:

I-co-sementation ibhekisa kwingxaki yokuba ezinye iinxalenye okanye amasuntswana adibane kunye ngexesha le-centrifugation, okwenza kube nzima ukuwahlula ngokupheleleyo. Le nto yenzeka xa umahluko woxinano phakathi kweenxalenye umncinci, nto leyo ekhokelela ekufudukeni kunye ngexesha le-centrifugation. I-co-sementation inokuba yingxaki ngakumbi xa usebenza ngemixube enzima, efana neesampuli zebhayoloji okanye ii-macromolecular complexes, apho ukwahlulwa kwezixhobo ezithile kunzima ngenxa yeempawu zazo ezifanayo.

3. Isampulu yoNgcoliseko:

Ngexesha lokufaka i-centrifugation, ungcoliseko lwesampulu lunokuba ngumceli mngeni omkhulu. Kubalulekile ukuqinisekisa ukuba iimeko kunye neeparamitha zokufaka i-centrifugation zilungiselelwe ukunciphisa ungcoliseko oluvela kwi-rotor, ityhubhu, okanye kwiityhubhu zokuqokelela. Ungcoliseko lunokuphazamisana nenkqubo yokwahlulahlula, nto leyo ekhokelela kwiisampulu ezingacocekanga. Ingqwalasela enzulu kufuneka inikwe ekukhetheni izixhobo ezifanelekileyo ze-rotor, ukusebenzisa iityhubhu ezifanelekileyo zokufaka i-centrifugation, kunye nokusebenzisa iinkqubo zokucoca ezisebenzayo ukuthintela ungcoliseko lwesampulu.

4. Isisombululo Esilinganiselweyo:

Isisombululo sokuqhekeka kunye nokwahlukana nge-centrifugation sixhomekeke kakhulu ekukhetheni i-centrifuge kunye ne-rotor. Iindlela ezahlukeneyo ze-centrifugation, ezifana ne-differential centrifugation okanye i-density gradient centrifugation, zibonelela ngamanqanaba ahlukeneyo esisombululo. Ngelixa i-density gradient centrifugation ibonelela ngokwahlukana kwesisombululo esiphezulu, ifuna amanyathelo ongezelelweyo kunye nezixhobo ezikhethekileyo. I-differential centrifugation, nangona ilula, inokuba nesisombululo esilinganiselweyo, nto leyo ekhokelela kwiibhendi ezihambelanayo kwiinxalenye eziphumayo. Abaphandi kufuneka baqwalasele ngononophelo isisombululo esifunekayo kwisicelo sabo esithile kwaye bakhethe indlela efanelekileyo ye-centrifugation ngokufanelekileyo.

5. Ixesha kunye neendleko:

Ukucoca nge-centrifugation kunokuba yinkqubo ethatha ixesha elide kwaye ibiza kakhulu. Ukufikelela ekuhlukaniseni nasekuhlukaniseni okufanelekileyo kunokufuna amanyathelo amaninzi, amaxesha amade okucoca nge-centrifugation, kunye neendlela ezikhethekileyo. Umzekelo, ukuze bafumane amaqhekeza acocekileyo kakhulu, abaphandi banokufuna ukwenza imijikelo elandelelanayo yokucoca nge-centrifugation, nto leyo ekhokelela ekwandeni kwexesha kunye notyalo-mali lwezixhobo. Ukongeza, ii-rotors kunye nee-centrifuges ezikhethekileyo ezikwaziyo ukwahlula ngesantya esiphezulu kunye nesisombululo esiphezulu zinokubiza kakhulu ukuzifumana nokuzigcina, nto leyo eyenza kubaluleke ukulinganisa iingenelo ngokuchasene neendleko ezinxulumene noko.

Isiphelo:

I-Centrifugation itshintshe kakhulu icandelo lokuqhekeka kunye nokwahlukana, ivumela abaphandi ukuba bafumane izinto ezicociweyo kwimixube enzima. Nangona kunjalo, ikwanayo nemida yayo. Iibhendi ezidibanisayo, i-co-sedimentation, ungcoliseko lwesampulu, isisombululo esilinganiselweyo, kunye nexesha kunye neendleko ezinxulumene nazo zonke ezi zinto zibeka imingeni ekusetyenzisweni ngempumelelo kwe-centrifugation. Nangona le mida, i-centrifugation isasebenza njengesixhobo esixabisekileyo kwiinkalo ezininzi zesayensi, kwaye ukuqhubela phambili okuqhubekayo kujolise ekusoyiseni le mingeni kunye nokuphucula ukusebenza kwayo kunye nokusebenza kwayo. Abaphandi kufuneka bahlole ngononophelo imida kwaye baphucule iiprotokholi zabo ze-centrifugation ukuqinisekisa ukwahlukana kunye nokuqhekeka ngempumelelo kwizicelo zabo ezithile.
