Tsoelo-pele ea Thermal Cycler: Phetohelo ho Amplification ea DNA

Li-cycle tsa mochesoe fetohile sesebelisoa sa bohlokoa bakeng sa bafuputsi le bo-rasaense mafapheng a baeloji ea limolek'hule le liphatsa tsa lefutso. Sesebelisoa sena se secha se fetotse mokhoa oa ho eketsa DNA, se etsa hore e be kapele, e sebetse hantle, 'me e nepahale ho feta leha e le neng pele. Bukeng ena, re tla hlahloba nts'etsopele ea li-thermal cyclers le tšusumetso ea tsona tšimong ea baeloji ea limolek'hule.

Khopolo ea ho potoloha ha mocheso, e kenyeletsang ho futhumatsa le ho pholisa motsoako oa karabelo khafetsa, ke motheo oa karabelo ea ketane ea polymerase (PCR). PCR ke mokhoa o eketsang kopi e le 'ngoe kapa tse 'maloa tsa karolo e le' ngoe ea DNA ka litaelo tse 'maloa tsa boholo, o hlahisang likopi tse likete ho isa ho tse limilione tsa tatellano e itseng ea DNA. Nts'etsopele ea li-cyclers tsa mocheso e bapetse karolo ea bohlokoa ts'ebelisong e pharaletseng le nts'etsopele ea theknoloji ea PCR.

Li-cycle tsa pele tsa mocheso li ne li le ngata 'me li hloka ho lokisoa ha mocheso ka letsoho le ho beoa leihlo khafetsa. Leha ho le joalo, ha theknoloji e ntse e tsoetse pele, li-cycle tsa mocheso tsa sejoale-joale li fetohile lisebelisoa tse rarahaneng tse ka laolang mocheso ka nepo le ho fihlella boiketsetso. Lintlafatso tsena li ekelitse lebelo le katleho ea ho eketsa DNA haholo, e leng se lumellang bafuputsi ho etsa PCR habonolo le ka mokhoa o tšepahalang.

E 'ngoe ea lintho tse ncha tsa bohlokoa theknolojing ea thermal cycler e bile ho hlahisoa ha gradient PCR, e lumellang hore mocheso o mongata oa annealing o lekoe ka nako e le 'ngoe tekong e le 'ngoe. Tšobotsi ena e ipakile e le molemo haholo ho ntlafatseng maemo a PCR bakeng sa template e itseng ea DNA, e bolokang bafuputsi nako le mehloli.

Ho phaella moo, ho kopanngwa ha bokgoni ba PCR ba nako ya sebele ho di-thermal cyclers ho atolositse tshebediso ya bona haholo. Real-time PCR, e tsejwang hape e le quantitative PCR, e lekola keketseho ya DNA ka nako ya sebele, e fana ka temohisiso ya bohlokwa mabapi le palo ya pele ya tatellano ya DNA e rerilweng. Sena se fetotse dibaka tse kang tlhahlobo ya tlhahiso ya lefutso, genotyping, le ho lemoha pathogen.

Ho fokotsoa ha li-thermal cycler ho fetohile mokhoa oa bohlokoa lilemong tsa morao tjena, ho susumetsoa ke tlhoko ea ho tsamaisoa habonolo le katleho. Li-thermal cycler tsena tse nyane, tse nkehang habobebe li fumane lits'ebetso lipatlisisong tsa masimo, tlhahlobo ea libaka tsa tlhokomelo, le libakeng tse nang le mehloli e fokolang moo meralo ea motheo ea laboratori ea setso e ka 'nang ea haella.

Ha re sheba pele, bokamoso bali-cycli tsa mochesoe tla bona boqapi bo bongata le ho feta. Mahlale a macha a kang a dijithale a PCR le mekhoa ea ho eketsa matla a isothermal a roba meeli ea ho eketsa matla a DNA 'me a fana ka menyetla e mecha ea ho lemoha nucleic acid ka potlako le ka bonolo.

Ka bokhutšoanyane, nts'etsopele ea li-thermal cyclers e bile le tšusumetso e kholo lefapheng la baeloji ea limolek'hule, e khanna tsoelo-pele lipatlisisong, tlhahlobong ea mafu le theknoloji ea baeloji. Ho tloha libolokong tsa pele tsa ho futhumatsa ka letsoho ho ea ho lisebelisoa tse tsoetseng pele tse iketsang tsa kajeno, li-thermal cyclers li fetotse keketseho ea DNA, li etsa hore ho be bonolo ho e sebelisa le ho tšepahala ho feta leha e le neng pele. Ha theknoloji e ntse e tsoela pele ho hatela pele, karolo ea li-thermal cyclers ho bopeng bokamoso ba baeloji ea limolek'hule e tla lula e le ea bohlokoa.
