    S: Intee in le'eg ayaa DNA -ga lagu darayaa nidaamka falcelinta PCR ee 50 μl?
    ytry
    S: Sidee loo kordhiyaa jajabyada dhaadheer?

    Tallaabada ugu horreysa waa inaad doorato polymerase habboon. Polymerase-ka caadiga ah ee Taq ma caddeyn karo sabab la xiriirta la'aanta waxqabadka 3'-5 ', iyo isku-dheelitir la'aantu waxay si weyn u yareyn doontaa wax-qabadka fidinta ee jajabyada. Sidaa darteed, polymerase -ka caadiga ah ee Taq si fiican uma kordhin karo jajabyada bartilmaameedka ee ka weyn 5 kb. Taq polymerase oo leh wax -ka -beddel gaar ah ama polymerase -ka kale ee aaminnimada sare leh waa in la xushaa si loo hagaajiyo hufnaanta fidinta oo loo daboolo baahiyaha ballaarinta jajabka dheer. Intaa waxaa dheer, xoojinta jajabyada dhaadheer sidoo kale waxay u baahan tahay hagaajin u dhiganta naqshadeynta asaasiga ah, waqtiga kala-soocidda, waqtiga kordhinta, pH-ka, iwm. Si looga hortago waxyeellada template, waqtiga denaturation -ka ee 94 ° C waa in lagu yareeyaa 30 seken ama ka yar wareeg kasta, iyo waqtiga heerkulka kor loogu qaadayo 94 ° C ka hor intaan la weyneyn waa inuu ka yaraadaa 1 min. Intaa waxaa dheer, dejinta heerkulka fidinta qiyaastii 68 ° C iyo naqshadeynta waqtiga kordhinta iyadoo la raacayo xaddiga 1 kb/min waxay xaqiijin kartaa xoojinta waxtarka leh ee jajabyada dhaadheer.

    S: Sidee loo hagaajiyaa daacadnimada xoojinta PCR?

    Heerka qaladka ee weyneynta PCR ayaa la dhimi karaa iyadoo la adeegsanayo polymerases DNA kala duwan oo leh aaminnimo sare. Waxaa ka mid ah dhammaan polymerase -ka Taq DNA ee la helay, Pfu enzyme wuxuu leeyahay heerka qaladka ugu hooseeya iyo daacadnimada ugu sareysa (eeg shaxda ku lifaaqan). Ka sokow xulashada enzyme, cilmi -baarayaashu waxay sii yareyn karaan heerka is -beddelka PCR iyagoo hagaajinaya xaaladaha falcelinta, oo ay ku jiraan hagaajinta halabuurka, xoojinta polymerase -ka heerkulka leh iyo hagaajinta lambarka wareegga PCR.
