Taq polymerase e nang le phetoho e khethehileng kapa botšepehi bo phahameng ba polymerase e lokela ho khethoa ho ntlafatsa katleho le ho fihlela litlhoko tsa sehlotšoana se selelele. Ntle le moo, kholiso ea likhechana tse telele e boetse e hloka phetoho e tsamaellanang ea moralo oa khale, nako ea denaturation, nako ea katoloso, pH ea buffer, jj. Hangata, li-primers tse nang le 18-24 bp li ka lebisa ho chai e ngata. Bakeng sa ho thibela tšenyo ea template, nako ea denaturation ho 94 ° C e lokela ho fokotsoa ho isa ho 30 sec kapa ka tlase ho potoloho, mme nako ea ho nyoloha mocheso ho ea ho 94 ° C pele amplification e lokela ho ba tlase ho 1 min. Ho feta moo, ho beha mocheso oa katoloso ka 68 ° C le ho rala nako ea katoloso ho latela sekhahla sa 1 kb / min ho ka netefatsa kholiso e sebetsang ea likhechana tse telele.

    Q: U ka ntlafatsa ts'epahalo ea kholiso ea PCR joang?

    Sekhahla sa phoso ea kholiso ea PCR se ka fokotsoa ka ho sebelisa li-polymerase tse fapaneng tsa DNA ka bots'epehi bo phahameng. Har'a li-polymerase tsohle tsa Taq DNA tse fumanehang ho fihlela joale, enzyme ea Pfu e na le sekhahla se tlase sa phoso le botšepehi bo phahameng ho fetisisa (bona tafole e hoketsoeng). Ntle le khetho ea enzyme, bafuputsi ba ka tsoela pele ho fokotsa sekhahla sa phetoho ea PCR ka ho ntlafatsa maemo a karabelo, ho kenyeletsoa le ho ntlafatsa sebopeho sa buffer, polasetiki ea thermostable polymerase le ho ntlafatsa palo ea potoloho ea PCR.
