Hlahloba ho tenyetseha ha li-thermal cyclers lipatlisisong

Li-cyclers tsa mocheso, tse tsejoang hape e le mechine ea PCR, ke lisebelisoa tsa bohlokoa baelojing ea limolek'hule le lipatlisiso tsa liphatsa tsa lefutso. Lisebelisoa tsena li sebelisoa ho matlafatsa DNA le RNA ka theknoloji ea karabelo ea ketane ea polymerase (PCR). Leha ho le joalo, ho feto-fetoha ha li-cyclers tsa mocheso ha ho felle feela lits'ebetsong tsa PCR. Sehloohong sena, re tla hlahloba litsela tse fapaneng tseo li-cyclers tsa mocheso li sebelisoang ka tsona lipatlisisong le bohlokoa ba tsona ho ntšetseng pele tsebo ea saense.

1. Ho holisa PCR

Mosebetsi o ka sehloohong oasesebelisoa sa ho futhumatsake ho etsa keketseho ea PCR, e leng ea bohlokoa bakeng sa mefuta e fapaneng ea lits'ebetso tsa baeloji ea limolek'hule. Ka ho beha sampole ea DNA kapa RNA letotong la liphetoho tsa mocheso, li-cyclers tsa mocheso li khothalletsa ho fetoha ha sebopeho, ho kenngoa ha metsi le ho atolosoa ha likhoele tsa nucleic acid, e leng se fellang ka keketseho ea exponential ea tatellano e itseng ea sepheo. Ts'ebetso ena e bohlokoa bakeng sa tlhahlobo ea liphatsa tsa lefutso, lithuto tsa polelo ea liphatsa tsa lefutso le ho lemoha li-agent tse tšoaetsanoang.

2. Bongata PCR (qPCR)

Ntle le PCR e tloaelehileng, li-thermal cyclers li sebelisoa bakeng sa PCR e ngata kapa qPCR, e leng se lumellang ho lekanya lipheo tsa nucleic acid ka har'a sampole. Ka ho kenyelletsa lidae kapa li-probe tse khanyang, li-thermal cyclers li ka lekanya pokello ea lihlahisoa tsa PCR ka nako ea sebele, li fana ka temohisiso ea bohlokoa mabapi le maemo a tlhahiso ea liphatsa tsa lefutso, mojaro oa vaerase le phapang ea liphatsa tsa lefutso.

3. PCR ea ho fetolela ka morao (RT-PCR)

Li-cycler tsa mocheso li bapala karolo ea bohlokoa ho reverse transcription PCR, mokhoa o fetolang RNA hore e be DNA e tlatsanang (cDNA) bakeng sa ho atolosoa hamorao. Mokhoa ona oa bohlokoa bakeng sa ho ithuta polelo ea liphatsa tsa lefutso, livaerase tsa RNA, le mekhoa ea ho kopanya mRNA. Se-cycler sa mocheso se nang le taolo e nepahetseng ea mocheso se bohlokoa katlehong ea liteko tsa RT-PCR.

4. PCR ea dijithale

Tsoelo-pele theknolojing ea thermal cycler e lebisitse nts'etsopele ea digital PCR, mokhoa o bonolo haholo oa ho lekanya ka botlalo li-nucleic acid. Ka ho arola karabelo ea PCR ka likete tsa li-microreaction tse ikhethileng, li-thermal cycler li ka fumana ka nepo mahloriso a pele a molek'hule e reretsoeng, e leng se etsang hore digital PCR e be sesebelisoa sa bohlokoa bakeng sa ho lemoha liphetoho tse sa tloaelehang le tlhahlobo ea phapang ea linomoro tsa kopi.

5. Tokisetso ea lilaebrari tsa tatellano ea moloko o latelang

Li-cycler tsa mocheso ke karolo ea bohlokoa ea ts'ebetso ea ho lokisa laeborari bakeng sa lits'ebetso tsa tatellano ea moloko o latelang (NGS). Ka ho etsa keketseho ea likaroloana tsa DNA tse thehiloeng ho PCR, li-cycler tsa mocheso li nolofalletsa kaho ea lilaeborari tsa tatellano ho tsoa linthong tse qalang tse fokolang, e leng se lumellang bafuputsi ho sekaseka genome eohle ea sebopuoa, transcriptome, kapa epigenome.

6. Boenjiniere ba Protheine le Phetoho ea Lisele

Ntle le ho eketsa nucleic acid, li-thermal cyclers li sebelisoa lithutong tsa boenjiniere ba protheine le tsa phetoho ea limolek'hule. Liphetoho tse tsamaisoang ke sebaka, ntlafatso ea tlhahiso ea protheine, le liteko tsa phetoho tse tataisoang hangata li itšetleha ka mekhoa e thehiloeng ho PCR, 'me li-thermal cyclers tse nang le taolo e nepahetseng ea mocheso le sekhahla se ts'oanang sa ho futhumatsa le ho pholisa li bohlokoa ho fumana liphetho tse nepahetseng le tse ka ikatisang.

7. Teko ea tikoloho le polokeho ea lijo

Li-cyclers tsa mocheso li boetse li sebelisoa litekong tsa polokeho ea tikoloho le lijo, haholo-holo ho lemoha likokoana-hloko tse bakang mafu a manyenyane, lintho tse phelang tse fetotsoeng liphatsa tsa lefutso (GMOs) le mafu a bakoang ke lijo. Liteko tse thehiloeng ho PCR tse etsoang ho li-cyclers tsa mocheso li nolofalletsa ho tsebahatsa ka potlako le ka ho khetheha litšila, ho netefatsa polokeho le boleng ba lisampole tsa lijo le tikoloho.

Ka kakaretso,li-cycli tsa mochesoke disebediswa tsa bohlokwa haholo baelojing ya dimolek'hule le dipatlisisong tsa lefutso, tse fanang ka mefuta e mengata ya ditshebediso tse fetang katoloso ya PCR ya setso. Ho tenyetseha ha tsona le ho nepahala ha tsona ho di etsa tsa bohlokwa bakeng sa diteko tse tlohang tlhahlobong ya tlhahiso ya lefutso ho isa tlhokomelong ya tikoloho. Ha theknoloji e ntse e tswela pele, di-cyclers tsa mocheso di ka nna tsa bapala karolo ya bohlokwa ho kganneng diphihlello tsa saense le boqapi.
