Ho ntlafatsa Bokgoni ba PCR ka ho Sebelisa Baesekele ba Thermal ba Tsoetseng Pele

Karabelo ea ketane ea polymerase (PCR) ke mokhoa oa motheo baelojing ea limolek'hule 'me o sebelisoa haholo ho ntlafatsa tatellano ea DNA. Bokhoni le ho nepahala ha PCR li angoa haholo ke thermal cycler e sebelisoang ts'ebetsong. Thermal cyclers e tsoetseng pele e bapala karolo ea bohlokoa ho ntlafatseng katleho ea PCR, e fana ka taolo e nepahetseng ea mocheso, sekhahla sa ho futhumatsa le ho pholisa ka potlako, le bokhoni bo tsoetseng pele ba ho etsa mananeo.

E 'ngoe ea likarolo tsa bohlokoa tsa e tsoetseng peleli-cycli tsa mochesoke taolo e nepahetseng ea mocheso. Ho boloka mocheso o itseng bakeng sa mehato ea ho fetoha ha naturation, annealing, le katoloso ho bohlokoa bakeng sa keketseho e atlehileng ea PCR. Sesebelisi se tsoetseng pele sa thermal cycler se netefatsa kabo e ts'oanang le e nepahetseng ea mocheso ka har'a liliba tsohle tsa sampole, se fokotsa liphetoho katlehong ea keketseho le ho fokotsa monyetla oa keketseho e seng e itseng.

Sekhahla sa ho futhumatsa le ho pholisa ka potlako ke karolo e 'ngoe ea bohlokoa ea li-cyclers tse tsoetseng pele tsa mocheso. Lisebelisoa tsena li na le theknoloji e thehiloeng ho Peltier e ka fetohang kapele lipakeng tsa mehato e fapaneng ea mocheso. Potoloho ena e potlakileng ea mocheso ha e boloke nako feela empa e boetse e fokotsa kotsi ea ho thehoa ha primer-dimer le ho amplification e seng e itseng, ka hona e eketsa ho hlaka le katleho ea PCR.

Ho phaella moo, di-cyclers tse tswetseng pele tsa mocheso di fana ka bokgoni bo tswetseng pele ba ho etsa mananeo, e leng se dumellang basebedisi ho etsa di-protocol tsa PCR ho latela ditlhoko tsa bona tse ikgethang tsa teko. Disebediswa tsena di fana ka ho tenyetseha ho seta gradient PCR, landing PCR, le di-protocol tse ding tse ikgethang, tse nolofalletsang ntlafatso ya maemo a PCR bakeng sa disete le di-template tse fapaneng tsa primer. Ho phaella moo, di-cyclers tse ding tse tswetseng pele tsa mocheso di na le di-interface tsa software tse ikgethang tse nolofatsang moralo wa protocol le tlhahlobo ya data, ka hona di ntlafatsa bokgoni ba teko ka kakaretso.

Ntle le likarolo tsena, li-cyclers tse ling tse tsoetseng pele tsa mocheso li fana ka mahlale a macha joalo ka likoahelo tse futhumetseng tse thibelang ho fifala le ho fetoha ha mouoane nakong ea potoloho ea PCR, ho netefatsa maemo a ts'ebetso a tsitsitseng le ho fokotsa tahlehelo ea sampole. Tse ling li ka kenyelletsa ts'ebetso ea gradient e ka ntlafatsang mocheso oa annealing bakeng sa lisampole tse ngata ka nako e le 'ngoe, e leng se ntlafatsang katleho le ts'epo ea PCR.

Bohlokoa ba ho sebelisa sesebelisoa sa ho futhumatsa se tsoetseng pele ho ntlafatsa katleho ea PCR bo ke ke ba feteletsoa. ​​Lisebelisoa tsena ha li nolofatse feela ts'ebetso ea PCR empa li boetse li thusa ho ntlafatsa ho ikatisa le ho nepahala ha liphetho tsa liteko. Ka ho fana ka taolo e nepahetseng ea mocheso, potoloho e potlakileng ea mocheso, le bokhoni ba ho etsa mananeo a tsoetseng pele, li-cyclers tsa ho futhumatsa tse tsoetseng pele li nolofalletsa bafuputsi ho fihlela keketseho e matla le e sebetsang ea PCR bakeng sa lits'ebetso tse fapaneng, ho kenyeletsoa tlhahlobo ea polelo ea liphatsa tsa lefutso, genotyping, le cloning.

Qetellong, e tsoetse peleli-cycli tsa mochesoe bapala karolo ea bohlokoa ho ntlafatseng katleho ea PCR. Taolo ea eona e nepahetseng ea mocheso, sekhahla sa ho futhumatsa le ho pholisa ka potlako, le bokhoni bo tsoetseng pele ba ho etsa mananeo bo thusa ho ntlafatsa ho nepahala, ho hlaka le ho ikatisa ha keketseho ea PCR. Bafuputsi ba ka rua molemo o moholo ka ho sebelisa li-cyclers tse tsoetseng pele tsa mocheso litekong tsa baeloji ea limolek'hule, qetellong li lebisa litšibollong tsa saense tse tšepahalang le tse nang le temohisiso haholoanyane.
