ʻO Robustart Taq DNA Polymerase
ʻO Robustart Taq DNA Polymerase kahi DNA polymerase hoʻomaka wela.ʻAʻole hiki i kēia huahana ke pale wale i ka hopena kikoʻī ʻole i hoʻokumu ʻia e ka annealing non-specific o nā primers a i ʻole ka hoʻohui mua ʻana i ke kaʻina o ka hoʻomākaukau ʻana o ka ʻōnaehana PCR a me ka hoʻonui.No laila, ʻoi aku ka maikaʻi o ka kikoʻī a ʻoi aku ka maikaʻi no ka hoʻonui ʻana i nā kumu hoʻohālike haʻahaʻa haʻahaʻa, a ua kūpono ia no ka hopena PCR amplification multiplexed.Eia kekahi, ʻoi aku ka maikaʻi o kēia huahana, a hiki ke loaʻa nā hopena amplification paʻa i nā ʻano like ʻole o ka PCR reactions.
Nā ʻāpana
1.5 U/μL Robustart Taq DNA polymerase
2.10 × PCR Buffer II (Mg²+ manuahi) (koe)
3.25 mM MgCl2(koho)
* 10 × PCR Buffer II (Mg²+ manuahi) ʻaʻohe dNTP a me Mg²+, e ʻoluʻolu e hoʻohui i nā dNTP a me MgCl2i ka hoʻomākaukau ʻana i ka ʻōnaehana pane.
Nā noi i manaʻo ʻia
1.Hoʻonui wikiwiki.
2.Hoʻonui nui.
3.Hoʻonui pololei i ke koko, swabs, a me nā laʻana ʻē aʻe.
4.ʻIke ʻana i nā maʻi hanu.
Kūlana Waihona
-20°C no ka mālama ʻana i ka wā lōʻihi, pono e hui pū ʻia ma mua o ka hoʻohana ʻana, e pale i ka hoʻoheheʻe pinepine ʻana.
*Inā hiki mai ka ua ma hope o ka hoʻolili ʻana, he mea maʻamau ia;ʻōlelo ʻia e hoʻohālikelike i ka mahana o ka lumi ma mua o ka hui ʻana a hoʻohana.
Wehewehe Unite
Hoʻokahi ʻāpana hana (U) i wehewehe ʻia ʻo ia ka nui o ka enzyme e hoʻokomo i ka 10 nmol o deoxyribonucleotide i loko o ka mea hiki ʻole ke hoʻololi i ka waika ma 74°C no 30 mau minuke me ka hoʻohana ʻana i ka DNA sperm salmon i hoʻāla ʻia ma ke ʻano he template/primer.
Ka Mana Mana
1.ʻOi aku ka maʻemaʻe electrophoretic SDS-PAGE ma mua o 98%.
2.Ka hoʻonui ʻana i ka naʻau, ka hoʻomalu ʻana i ka pūʻulu, kūpaʻa.
3.ʻAʻohe hana nuclease exogenous, ʻaʻohe exogenous endonuclease a exonuclease contamination

Nā memo:
1) a.ʻAʻohe dNTP a me Mg²+ i ka pale, e ʻoluʻolu e hoʻohui i nā dNTP a me MgCl2i ka hoʻomākaukau ʻana i ka ʻōnaehana pane.
2) b.Inā hoʻohana ʻia no qPCR/qRT-PCR, pono e hoʻohui ʻia nā ʻimi fluorescent i ka ʻōnaehana pane.ʻO ka mea maʻamau, e hāʻawi ka hopena hope loa o 0.2 μM i nā hopena maikaʻi;inā maikaʻi ʻole ka hana ʻana, hiki ke hoʻoponopono ʻia ke kumu kumu ma ka laulā o 0.2-1 μM.Hoʻomaʻamaʻa pinepine ʻia ka neʻe ʻana o ka probe ma ka laulā o 0.1-0.3 μM.Hiki ke hana ʻia nā hoʻokolohua gradient concentration no ka ʻimi ʻana i ka hui maikaʻi loa o ka primer a me ka probe.

1.ʻAʻole pono e emi ka helu hoʻonui o ka DNA polymerase wikiwiki ma mua o 1 kb/10 s.ʻOkoʻa ka piʻi ʻana o ka wela a me ka hāʻule ʻana, ke ʻano hoʻomalu wela a me ka pono o ka lawe ʻana i ka wela o nā mea hana PCR like ʻole, no laila e manaʻo ʻia e hoʻopaʻa i nā kūlana hopena maikaʻi loa no ka mea hana PCR wikiwiki.
2.Hiki ke hoʻololi ʻia ka ʻōnaehana, me ka kikoʻī kiʻekiʻe a me ka naʻau.
3.He kūpono no ka hoʻohana ʻana e like me ka PCR detection reagents kiʻekiʻe, a hiki ke hoʻohana ʻia i nā hopena PCR amplification multiplex.
4.5′→3′ hana polymerase, 5′→3′ hana exonuclease;ʻaʻohe 3′→5′ hana exonuclease;ʻaʻohe hana hoʻoponopono.
5.He kūpono no ka hoʻāʻo qualitative a me ka quantitative o PCR a me RT-PCR.
6.ʻO ka hopena 3′ o ka huahana PCR ʻo A, hiki ke hoʻopili pololei ʻia i kahi vector T.
7.Manaʻo ʻia ke ʻano hana ʻekolu no nā primers me nā mahana annealing haʻahaʻa a i ʻole no ka hoʻonui ʻana i nā ʻāpana ʻoi aku ka lōʻihi ma mua o 200 bp.
