Chiitiko Tsananguro

Kuita kwe1 unit (U) Pfu DNA Polymerase kunotsanangurwa seuwandu hweiyo enzyme inodiwa kuisa 10 nmol deoxynucleotides muzvinhu zvine asidi-zvisingasviki pa74 ° C mukati me30 min uchishandisa salmon sperm DNA se template / primer.

Kudzora Kwemhando

Rucheno rweSDS-PAGE kuona rwunopfuura 99%; Hapana chiitiko che exogenous nuclease chakawanikwa; Imwe-kopi jeni mugenome yemunhu inogona kukwidziridzwa zvinobudirira; Hapana chiitiko chakakosha chinoshanduka kana chakachengetwa mukamuri tembiricha kwevhiki rimwe.

Main technical Parameter

Iine 3'-5 'chiitiko chekuregerera uye hapana 5'-3' chiitiko chekuregerera. Kuwedzeredzwa kumhanya kweDNA kukwidziridzwa kwakadzikira pane kweTaq polymerase, uye kazhinji kuwedzeredza kumhanya kwePfu enzyme kuri 0.5-1 kb paminiti. Iko kudziya kwemafuta kwePfu kuri nani pane Taq. Kune matemplate ane yakakwira GC zvemukati, iyo denaturation tembiricha inogona kuwedzerwa kusvika 98 ° C, iyo isina mhedzisiro pane chiitiko chePfu polymerase. Iyo PCR chigadzirwa inoguma-yakapera, iyo inogona kuwedzerwa ne3'-dA overhangs isati yasungirirwa neTA vector kana kuumbwa neyakajeka-yakapera vector

Zvishandiso

Inogona kushandiswa pakukwirira kwekuvimbika kweDNA, senge gene expression cloning, saiti-inotungamirwa mutation, imwechete nucleotide polymorphism (SNP) kuongorora uye kupera kugadzirisa.

    ytry
    Mubvunzo: Ungawedzera sei zvidimbu zvakareba?

    Nhanho yekutanga ndeyekusarudza yakakodzera polymerase. Yakajairwa Taq polymerase haigone kuongorora nekuda kwekushayikwa kwe3'-5 'exonuclease chiitiko, uye kusaenderana kuchadzora zvakanyanya kuwedzera kwekuwedzera kwezvimedu. Naizvozvo, yenguva dzose Taq polymerase haigone kunyatsokwenenzvera zvidimbu zvakanangwa zvakakura kupfuura 5 kb. Taq polymerase ine yakakosha nadzurudzo kana imwe yakanyanya kutendeka polymerase inofanirwa kusarudzwa kuvandudza kuwedzera kwekuita uye kuzadzikisa zvido zvehurefu hwakareba kuwedzera. Uye zvakare, kukwidziridzwa kwezvimedu zvidimbu kunodawo kuenderana kunoenderana kwekutanga dhizaini, nguva yekuwedzeredza, nguva yekuwedzera, buffer pH, nezvimwe. Kazhinji, ma primers ane 18-24 bp anogona kutungamira mukukohwa kuri nani. Kuti tidzivirire kukuvara kwetemplate, iyo nguva yekuratidzira iri pa94 ° C inofanirwa kudzikiswa kusvika pamasekondi makumi matatu kana mashoma pasiringi, uye iyo nguva yekukwira tembiricha kusvika pa94 ° C pamberi pekukudziridza inofanira kunge iri pasi pe1 min. Zvakare, kumisikidza iyo yekuwedzera tembiricha ingangoita se68 ° C uye nekugadzira iyo yekuwedzera nguva zvinoenderana nehuremu hwe1 kb / min inogona kuve nechokwadi chinoshanda kukwidziridzwa kwezvimedu zvidimbu.

    Mubvunzo: Ungavandudza sei kukwidziridzwa kuvimbika kwePCR?

    Chiyero chekukanganisa kwePCR kukwidziridzwa kunogona kudzikiswa nekushandisa akasiyana maDNA ma polymerase nekuvimbika kwakanyanya. Pakati pese maTaq DNA ma polymerases akawanikwa kusvika parizvino, Pfu enzyme ine yakaderera kukanganisa chikanganiso uye yakatendeka kuvimbika (ona tafura yakasungirirwa). Pamusoro pekusarudzwa kwe enzyme, vatsvagiri vanogona kuwedzera kudzikisa huwandu hwePCR nekushandura mamiriro ekugadzirisa, kusanganisira kugadziridza bhaisikopo, kuwanda kweinopisa polymerase uye kugadzirisa huwandu hwePCR.
