Haʻahaʻa haʻahaʻa a ʻaʻohe DNA

Nui nā kumu e pili ana i ka hua o ka DNA genomic, me ke kumu o ka hāpana, ka makahiki o ka hāpana, nā kūlana mālama o ka hāpana, a me ka hana.

ʻAʻole hiki ke loaʻa ka DNA Genomic i ka wā o ka unuhi ʻana

1. Hoʻopaʻa pono ʻole ʻia a mālama ʻia paha nā mea kikoo no ka lōʻihi loa, e hopena i ka hōʻino ʻana o ka DNA genomic.

Manaʻo: E mālama i nā laʻana o ka ʻiʻo i loko o ka nitrogen wai a i ʻole -20°C;e ho'āʻo e hoʻohana i nā laʻana hou i hōʻiliʻili ʻia no ka unuhi ʻana i ka DNA genomic.

2. ʻAʻole hiki ke unuhi ʻia ka DNA genomic pili i ka liʻiliʻi loa.

Manaʻo Manaʻo: No nā laʻana ʻiʻo i mālama ʻia no ka manawa lōʻihi a i ʻole ka hoʻohaʻahaʻa ʻana i ka DNA genomic koʻikoʻi, hiki ke hoʻonui ʻia ka nui o nā laʻana iʻa no ka unuhi ʻana i ka DNA genomic nui.Hiki ke hoʻoholo ʻia ka nui o ka hāpana e like me ka pono o ka DNA, akā ʻaʻole pono ka laʻana hou ma mua o 100mg, a ʻaʻole pono ka hāpana maloʻo ma mua o 30mg.

3. ʻAʻole i lepo ka hāpana me ka naikokene wai a waiho ʻia no ka lōʻihi loa ma hope o ka wai nitrogen.

Manaʻo Manaʻo: I ka wā o ka unuhi ʻana i ka DNA, pono e hoʻoheheʻe ʻia ka hāpana me ka nitrogen wai e wāwahi ai i ka paia o ke kelepona;ma hope o ka wili ʻana, e ʻoluʻolu e hoʻololi i ka pauka hāpana i PL1 i hoʻomehana ʻia ma 65°C i ka hikiwawe loa (ke hoʻoheheʻe ʻia ka lepo lepo, e hoʻomaka ana ka DNA genomic e hoʻohaʻahaʻa koke) .

4. ʻO ka mālama pono ʻole ʻana o Foregene Protease ka hopena i ka hoʻemi ʻana a i ʻole ka hana ʻole.

Manaʻo: E hōʻoia i nā kūlana mālama o Foregene Protease a i ʻole e hoʻololi iā ia me kahi Foregene Protease hou no ka hydrolysis enzymatic.

5. Ua mālama pono ʻole ʻia a mālama ʻia paha ka pahu no ka lōʻihi loa, e hāʻule ana kekahi mau mea i loko o ka pahu.

Manaʻo Manaʻo: E kūʻai mai i kahi pahu hoʻoheheʻe DNA genomic mea kanu hou no nā hana pili.

6. Hoʻohana pono ʻole i ka pahu.

Manaʻo Manaʻo: E kūʻai i kahi mea kanu DNA Isolation Kit i hoʻolaʻa ʻia i nā laʻana no ka unuhi ʻana a me ka hoʻomaʻemaʻe ʻana i ka DNA genomic mea kanu.

7. E hoʻopaʻa i ka WB me ka hoʻohui ʻole i kahinhydrous ethanol.

Manaʻo Manaʻo: E hōʻoia e hoʻohui i ka leo kūpono o ka ethanol piha i ka Buffer WB.

8. ʻAʻole i kulu pono ʻia ka eluent ma luna o ka membrane silica.

Manaʻo: E hoʻohui i ka eluent i hoʻomehana mua ʻia ma 65℃dropwise i ka waena o ka silica gel membrane, a waiho ia ma ka lumi wela no 5 minuke e hoonui i ka elution pono.

ʻO ka unuhi ʻana no ka loaʻa ʻana o ka DNA genomic haʻahaʻa

1. Ua mālama pono ʻole ʻia ka hāpana no ka lōʻihi loa, e hopena i ka hōʻino ʻana o ka DNA genomic.

Manaʻo Manaʻo: E mālama i nā laʻana kiko ma -20℃;e ho'āʻo e hoʻohana i nā laʻana kikoo hou i hōʻiliʻili ʻia no ka unuhi ʻana i ka DNA genomic.

2. Inā he liʻiliʻi loa ka nui o nā mea kikoo, e emi ana ka DNA genomic i unuhi ʻia.

Manaʻo Manaʻo: Ua waiwai kekahi mau mea kanu i ka wai, e like me nā mea kanu wai e like me ka algae, etc.

3. ʻAʻole i hoʻomaloʻo maikaʻi ʻia nā laʻana me ka naikokene wai a i ʻole waiho ʻia ma ka lumi wela no ka lōʻihi ma hope o ka wili ʻana.

Manaʻo Manaʻo: Pono e lawa ka wili naikokene wai, a ʻo ka paia o ke kelepona hāpana e wāwahi ʻia e like me ka hiki;ma hope koke o ka wili ʻana, pono e hoʻoneʻe ʻia ka pauka hāpana i 65℃preheated Buffer PL1 no ka hana aʻe.

4. ʻAʻole hoʻohana i ka pahu kūpono.

Manaʻo Manaʻo: E hoʻohana i ka Plant DNA Isolation Kit no ka unuhi a hoʻomaʻemaʻe i ka DNA genomic mea kanu.

5. ʻO ka mālama pono ʻole ʻana o Foregene Protease ka hopena i ka hoʻemi ʻana a i ʻole ka hana ʻole.

Manaʻo: E hōʻoia i nā kūlana mālama o Foregene Protease a i ʻole e hoʻololi iā ia me kahi Foregene Protease hou no ka hydrolysis enzymatic.

6. Pilikia maikaʻi

Manaʻo: E ʻoluʻolu e hoʻohana i ka Buffer EB no ka elution;inā hoʻohana ʻo ddH₂ʻO a i ʻole nā ​​mea eluent ʻē aʻe, e hōʻoia i ka pH o ka eluent ma waena o 7.0-8.5.

7. ʻAʻole kulu pololei ka eluent

Manaʻo Manaʻo: E ʻoluʻolu e hoʻohui i ka hāʻule elution i waenakonu o ka membrane silica a waiho i ka lumi wela no 5 mau minuke e hoʻonui ai i ka pono elution.

8. He liʻiliʻi loa ka leo eluent

Manaʻo: E ʻoluʻolu e hoʻohana i ka eluent no ka elution DNA genomic e like me nā kuhikuhi, ʻaʻole liʻiliʻi ma lalo o 100μl.

Ua unuhi ʻia ka DNA genomic me ka maʻemaʻe haʻahaʻa

ʻO ka haʻahaʻa haʻahaʻa o ka genomic DNA e alakaʻi i ka hāʻule ʻole a i ʻole ka hopena maikaʻi ʻole o nā hoʻokolohua o lalo, e like me: ʻaʻole hiki ke ʻoki ʻia ka enzyme, a ʻaʻole hiki ke loaʻa ka ʻāpana gene i ka PCR.

1. ʻO ka hoʻohaumia ʻana o nā protein ʻokoʻa, ka hoʻohaumia RNA.

Nānā: ʻAʻole i hoʻohana ʻia ʻo Buffer PW e holoi i ke kolamu;ʻAʻole i hoʻohana ʻia ʻo Buffer PW e holoi i ke kolamu ma ka wikiwiki centrifugation pololei.

Manaʻo: e hoʻāʻo e hōʻoia i ka ʻole o ka ua i loko o ka supernatant ke hele ka supernatant i ke kolamu;e holoi i ke kolamu hoʻomaʻemaʻe me Buffer PW e like me nā kuhikuhi, a ʻaʻole hiki ke haʻalele ʻia kēia hana.

2. Impurity ion pollution.

Nānā: Ua kāpae ʻia ke kolamu holoi WB Buffer a i ʻole holoi ʻia hoʻokahi wale nō, e hopena i ke koena ionic contamination.

Manaʻo Manaʻo: E holoi ʻelua me ka Buffer WB e like me nā ʻōlelo aʻoaʻo e wehe i nā koena ion e like me ka hiki.

3. ʻO ka haumia RNase.

Nānā: Hoʻohui ʻia ʻo Exogenous RNase i ka Buffer;ʻO ka hana holoi hewa ʻole ma Buffer PW e hopena i ke koena RNase a pili i nā hana hoʻokolohua RNA i lalo, e like me ka transcription in vitro.

Manaʻo: Foregene series nucleic acid extraction kits hiki ke wehe i ka RNA me ka loaʻa ʻole o RNase hou, a ʻaʻole pono nā reagents a pau i ka Plant DNA Isolation Kit i ka RNase;e holoi i ke kolamu hoʻomaʻemaʻe me Buffer PW e like me nā kuhikuhi, a ʻaʻole hiki ke haʻalele ʻia kēia hana.

4. Nā koena ethanol.

Nānā: Ma hope o ka holoi ʻana i ke kolamu hoʻomaʻemaʻe me Buffer WB, ʻaʻole i hana ʻia ka centrifugation paipu ʻole.

Manaʻo: E hahai i nā ʻōlelo aʻoaʻo no ka centrifugation paipu nele.
