Li-Centrifuge: Ho Arola Liphiri tsa Saense

Selelekela:

Lefatšeng le khahlang la lipatlisiso tsa saense, e 'ngoe ea lisebelisoa tse sebelisoang haholo ke centrifuge. Sesebelisoa sena se bohlale se nolofalletsa bo-rasaense ho arola lintho tse fapaneng le ho notlolla liphiri tse patiloeng ka hare ho tsona. Ho tloha ho tsa tlhahlobo ea mafu ho ea ho meriana le ntho e 'ngoe le e 'ngoe e lipakeng, centrifuge e bapala karolo ea bohlokoa masimong a mangata a saense. Sehloohong sena, re hlahloba ka botebo ts'ebetso ea centrifuge 'me re hlahloba kamoo e nolofalletsang bo-rasaense ho arola le ho ithuta lintho ka tekanyo e nyenyane haholo.

I. Mekhaniki ea Sekhomaretsi:

Bohareng ba yona, centrifuge ke sesebediswa se potolohang ka lebelo le phahameng, se hlahisa matla a centrifugal. Matla ana a tswa bohareng mme a kganna dikarolwana tse boima ho ya pheletsong e ka ntle ya sejana se potolohang, a di arola dinthong tse bobebe. Ka molaomotheo ona wa motheo, centrifuge di kgona ho arola metswako, ho arola disele, le ho etsa ditshebetso tse ding tse fapaneng tsa bohlokwa dipatlisisong tsa saense.

II. Mekhoa ea ho Centrifugation:

Ho centrifugation ho tla ka mefuta e fapaneng, e 'ngoe le e 'ngoe e etselitsoe lipotso tse itseng tsa saense. A re hlahlobeng tse ling tsa mekhoa e tloaelehileng e sebelisoang ke bo-rasaense:

a) Ho Fokotsa Dipharologanyo tsa ho Fokotsa: Mokhoa ona o kenyelletsa mekhahlelo e mengata ea ho centrifuga ka lebelo le eketsehileng ho arola lintho butle-butle ho latela bongata ba tsona. Ka ho fetola maemo a centrifuge bakeng sa potoloho ka 'ngoe, bo-rasaense ba ka arola likarolo tse fapaneng ka katleho ka har'a motsoako.

b) Ho Fokotsa Methapo e Meholo: Ho sebedisa di-gradients tsa bongata, mokhoa ona o kenyeletsa ho beha sampole hodima sebaka se mahareng sa gradient le ho e centrifuga. Ha dikarolwana di ntse di feta ka hara gradient, di a arohana ho latela bongata ba tsona bo phaphametseng, di etsa dihlopha tse fapaneng ho potoloha tube. Mokgwa ona o thusa haholo bakeng sa ho arola dimolek'hule tse nang le bongata bo tshwanang.

c) Isopycnic Centrifugation: Mokhoeng ona, o tsejoang hape e le buoyant density centrifugation, density ea tharollo e ts'oana le ea likaroloana tse ithutoang. Ka lebaka leo, likaroloana li lula li leketlile libakeng tse itseng ka har'a tube ea centrifuge, e leng se nolofalletsang bo-rasaense ho li arola ho latela mefuta e fapaneng ea density ea buoyant.

III. Ts'ebeliso ea Li-Centrifuge:

Li-centrifuge li fumana lits'ebetso mafapheng a mangata a saense. Mehlala e 'maloa e hlokomelehang ke ena:

a) Patlisiso ea Biomedical: Lefapheng la lipatlisiso tsa biomedical, li-centrifuge lia hlokahala haholo. Bo-rasaense ba li sebelisa ho arola le ho ithuta likarolo tse fapaneng tsa sele, tse kang mitochondria, nuclei le li-organelle, tse thusang ho utloisisa lits'ebetso tsa sele le mekhoa ea mafu.

b) Tlhahlobo ea Bongaka: Li-Centrifuge li bapala karolo ea bohlokoa lilaboratoring tsa bongaka, li nolofalletsa ho aroloa ha lisampole tsa mali ka likarolo tse fapaneng. Ka ho potoloha mali ka lebelo le phahameng, li nolofalletsa ho aroloa ha lisele tse khubelu le tse tšoeu tsa mali, plasma le li-platelet, li thusa litekong tsa tlhahlobo, ho ngola mali le mekhoa ea phekolo.

c) Ntlafatso ea Meriana: Li-Centrifuge li bohlokoa lipatlisisong le nts'etsopele ea meriana. Li thusa ho ntšoeng le ho hloekisoeng ha liprotheine tsa phekolo, ho aroloa ha metsoako ea meriana le ho laola boleng ba lihlahisoa tsa meriana.

d) Tlhahlobo ea Tikoloho: Mekhoa ea ho centrifugation e boetse e sebelisoa tlhahlobong ea tikoloho ho ithuta libaka tsa metsi, lisampole tsa mobu le moea. Ka ho arola lintho tse fapaneng tse teng lisampoleng tsena, bo-rasaense ba ka khetholla litšila, ba ithuta lichaba tsa likokoana-hloko, le ho hlahloba bophelo bo botle ba tikoloho ka kakaretso.

e) Patlisiso ea DNA: Li-centrifuge li bohlokoa haholo lipatlisisong tsa DNA, li lumella bo-rasaense ho ntša le ho ithuta limolek'hule tsa DNA. Ka ho arola DNA ho likarolo tse ling tsa sele, bafuputsi ba ka e sekaseka, ba etsa liteko tsa liphatsa tsa lefutso, le ho senola liphiri tse kentsoeng ka har'a liphatsa tsa rona tsa lefutso.

IV. Tsoelo-pele Theknolojing ea Centrifuge:

Ho theosa le dilemo, theknoloji ya centrifuge e bile le kgatelopele e kgolo, e leng se lebisitseng tshebetsong e ntlafetseng le ho nepahala ha ho arola dintho. Dikarolo tsa morao-rao di kenyeletsa:

a) Bokgoni ba Lebelo le Phahameng: Di-centrifuge tsa sejwalejwale di ka fihlella lebelo la ho potoloha la diphetoho tse fihlang ho 100,000 ka motsotso (RPM). Sena se dumella karohano e sebetsang hantle, dinako tse fokotsehileng tsa tshebetso, le chai e ntlafetseng.

b) Mekhoa ea ho Sehatsetsing: Mechini e meng ea ho seha e na le litsamaiso tsa ho pholisa tse hahiloeng kahare, tse nolofalletsang lisampole tse amehang mochesong ho sebetsoa ntle le ho beha botšepehi ba tsona kotsing. Mekhoa ena ea ho sehatsing e boloka mocheso o tlase nakong ea ho seha, e thibela ho senyeha le ho boloka boleng ba sampole.

c) Meralo e Tsoetseng Pele ya Rotor: Moralo wa rotor o fetohile ho amohela mefuta e fapaneng ya dibolumo le mefuta ya disampole. Ho tloha ho di-microcentrifuge tse etseditsweng disampole tse nyane ho isa ho di-centrifuge tse nang le bokgoni bo boholo ba mokatong, ho tenyetseha ho fanwang ke meralo e fapaneng ya rotor ho dumella bo-rasaense ho sebetsa ka mefuta e mengata ya boholo ba disampole le ho ntlafatsa dikarohano.

d) Boiketsetso le Bokgoni ba ho Etsa Lenaneo: Di-centrifuge tse ngata tsa sejwalejwale di na le dikgetho tse tswetseng pele tsa boiketsetso, ho kenyeletswa le diprothokhole tse ka hlophiswang le di-interface tse bonolo ho di sebedisa. Dikarolo tsena di nolofatsa tshebetso, di eketsa bokgoni ba ho ikatisa hape, mme di nolofalletsa tshebetso ya disampole tse ngata ntle le tlhokomelo.

Qetello:

Ho tloha ho senoleng liphiri tsa lits'ebetso tsa sele ho isa ho fumaneng mafu le ho sibolla meriana e mecha, li-centrifuge li nolofalletsa bo-rasaense ho arola le ho ithuta lintho ka nepo. Ka lits'ebetso tsa tsona tse ngata le tsoelo-pele e tsoelang pele ea theknoloji, lisebelisoa tsena tse ikhethang li bapala karolo ea bohlokoa lipatlisisong tsa saense. Ha re ntse re teba haholoanyane liphiring tsa saense, li-centrifuge ntle ho pelaelo li tla tsoela pele ho ba ka pele, li senola mathata a lefats'e la rona, karohano e le 'ngoe ka nako.
