Kev pom zoo: Lub elution ntim ntawm purification kem yog 50-200 μl;Yog tias cov nyhuv elution tsis txaus siab, nws raug nquahu kom txuas ntxiv chav tsev kub tso sijhawm tom qab ntxiv preheated RNase-Free ddH₂O, piv txwv li rau 5-10 min.

8.Cov purification kem muaj ethanol residue tom qab Buffer RW2 ntxuav.

Kev pom zoo: Yog tias muaj ethanol residue tom qab Buffer RW2 ntxuav, khoob raj centrifugation rau 1min, lub sij hawm rau lub raj khoob centrifugation ua hauj lwm yuav nce mus rau 2min, los yog purification kem yuav muab tso rau hauv chav tsev kub rau 5 min kom txaus tshem tawm cov seem ethanol.

Purified RNA yog degraded

Qhov zoo ntawm RNA purified yog muaj feem xyuam rau tej yam xws li kev khaws cia ntawm tus qauv, RNase contamination, thiab manipulation, thiab lwm yam.

1. Cov qauv ntaub so ntswg tsis khaws cia rau lub sijhawm.

Kev pom zoo: Yog tias tsis siv cov ntaub so ntswg los yog cov hlwb tsis siv raws sij hawm tom qab sau, tam sim ntawd cryopreserve ntawm -80 ° C los yog kua nitrogen.Txhawm rau rho tawm RNA, siv cov ntaub so ntswg tshiab lossis cov qauv ntawm tes thaum twg los tau.

2. Rov qab khov-thawing ntawm cov ntaub so ntswg kuaj.

Kev pom zoo: Thaum khaws cov ntaub so ntswg, nws yog qhov zoo tshaj plaws los txiav lawv rau hauv me me rau kev khaws cia, thiab tshem tawm ib qho ntawm cov khoom thaum siv lawv kom tsis txhob rov khov-thawing ntawm cov qauv thiab degradation ntawm RNA.

3. RNase yog qhia los yog tsis hnav hnab looj tes, qhov ncauj qhov ntswg, thiab lwm yam thaum lub sijhawm ua haujlwm.

Kev pom zoo: RNA extraction thwmsim yog ua tau zoo tshaj plaws nyob rau hauv cais RNA manipulation chav thiab lub rooj yog cleared ua ntej qhov kev sim.

Hnav cov hnab looj tes thiab lub qhov ncauj qhov ntswg pov tseg thaum lub sijhawm sim ua kom txo qis RNA degradation los ntawm kev qhia txog RNase.

4. Cov tshuaj tiv thaiv kab mob muaj RNase thaum siv.

Kev Pom Zoo: Hloov nrog Cov Tsiaj Tag Nrho Tag Nrho RNA cais tawm tshiab rau cov kev sim cuam tshuam.
