■ Zosavuta komanso zachangu: Chikwacho chimagwiritsa ntchito ukadaulo wopanga wa plasmid wokulitsa. Zimangofunikira masitepe 4 kuti zitsimikizire kusinthaku kuchokera ku zovuta zamtchire kupita ku zovuta zosintha, popanda njira zowonongera nthawi komanso zotenga ntchito monga maulendo angapo a PCR ndi ma cloning.
■ Zoyambira bwino kwambiri: Chikwamacho chimatsata mfundo yophatikizira pang'ono kapangidwe kake, kuti ma plasmid owonjezera atha kupezeka mwakukulitsa.
■ Kugwiritsa ntchito kwambiri: Chidacho sichitha kungosintha tsamba limodzi, komanso kusintha kwamasamba ambiri. Imatha kusintha mpaka masamba 5.
■ Kusinthasintha kwamphamvu: Chikwamacho chitha kusintha kusintha kwa ma plasmid okhala ndi kukula kokwanira 10 kb, makamaka kuphimba ma plasmids omwe amagwiritsidwa ntchito kwambiri.
■ Kusintha kwakukulu: zida zimatha kugayidwa kawiri pamiyeso ya methylated plasmid mu vitro ndi mu vivo, kuwonetsetsa kuti masinthidwe apamwamba kwambiri.

Kukonzekera kwa Site-Mutation Reaction ndi PCR

■ Pakusintha kamodzi kokha pamasamba ambiri, kusinthako kumakhala kotsika poyerekeza ndikusintha kwamasamba amodzi chifukwa cha kuchuluka kwamasamba. Malinga ndi kafukufuku wathu woyesera, kuchuluka kwa malo osintha masinthidwe kukafika 5, kusinthaku kuli kotsika mpaka 50%. Chifukwa chake, pakadali pano, ndikulimbikitsidwa kuti muwonjezere kuchuluka kwama clones otsimikizika.
■ Chida chimathandizira kusintha kwamasamba ambiri, kuti kuyesa kusintha kumasintha nthawi imodzi m'magulu osiyanasiyana. Malire apamwamba amalo osintha masinthidwe akadali 5.
■ Akuti ma plasmids oyang'anira ndi zopangira zomwe zimapezeka mu zida ziyenera kugwiritsidwa ntchito popanga kuyesa kwatsopano kuti athe kuwunika zovuta zoyeserera.

    Q: Ndi ma template angati a DNA omwe akuyenera kuwonjezeredwa mu 50 μl PCR reaction system?
    ytry
    Q: Momwe mungakulitsire zidutswa zazitali?

    Gawo loyamba ndikusankha ma polymerase oyenera. Wokhazikika Taq polymerase sangathe kuwerengera chifukwa chosowa 3'-5 'exonuclease, ndipo kusamvana kumachepetsa kwambiri kukulitsa kwa zidutswa. Chifukwa chake, Taq polymerase wamba sangathe kukulitsa bwino zidutswa zokulirapo zopitilira 5 kb. Taq polymerase yosinthidwa mwapadera kapena kukhulupirika kwakukulu kwa polymerase kuyenera kusankhidwa kuti ikuthandizire kukulitsa zowonjezera ndikukwaniritsa zosowa zamagawo ataliatali. Kuphatikiza apo, kukulitsa kwa zidutswa zazitali kumafunikanso kusintha kofananira kwa kapangidwe koyambira, nthawi yoperekera nthawi, nthawi yowonjezera, pH ya buffer, ndi zina zambiri. Nthawi zambiri, zopangira 18-24 bp zimatha kubweretsa zokolola zabwino. Pofuna kupewa kuwonongeka kwa template, nthawi yodzitchinjiriza yomwe ili pa 94 ​​° C iyenera kuchepetsedwa kukhala 30 sec kapena kuchepera pakazungulira, ndipo nthawi yokwera kutentha mpaka 94 ° C kukweza kusanachepe 1 min. Kuphatikiza apo, kukhazikitsa kutentha kwazitali pafupifupi 68 ° C ndikupanga nthawi yowonjezera malinga ndi kuchuluka kwa 1 kb / min kumatha kutsimikizira kukulitsa kwa zidutswa zazitali.

    Q: Kodi mungakonze bwanji kukulitsa kukhulupirika kwa PCR?

    Kuchuluka kwa zolakwika za PCR kumatha kuchepetsedwa pogwiritsa ntchito ma polymerases a DNA mosadukiza. Mwa ma Taq DNA polymerases onse omwe apezeka mpaka pano, enzyme ya Pfu ili ndi zolakwika zotsika kwambiri komanso kukhulupirika kwambiri (onani tebulo lolumikizidwa). Kuphatikiza pa kusankha kwa ma enzyme, ofufuza amatha kupititsa patsogolo kusintha kwa kusintha kwa PCR pokonza momwe zinthu zikuyendera, kuphatikiza kukhathamiritsa kophatikizira, kuchuluka kwa ma polymerase osakanikirana ndikukwaniritsa kuchuluka kwa PCR.
