RNA muab rho tawm los ntawm paraffin-embedded rat daim qauv siv RNAprep Pure FFPE Kit. Tus nqi piv txwv: 15 mg nas lub siab; Kev tshem tawm ntim: 50 μl; Chaw thau khoom ntim: 8 μl M: TIANGEN Marker III 1-4: nas lub siab FFPE |
A-1 Cell lysis lossis homogenization tsis txaus
---- Txo cov qauv siv, nce tus nqi ntawm lysis tsis, nce homogenization thiab lysis lub sijhawm.
A-2 Cov qauv piv txwv loj heev
---- Txo tus nqi siv piv txwv lossis nce tus nqi ntawm lysis tsis.
A-1 Tsis txaus lysis ntawm tes lossis homogenization
---- Txo cov qauv siv, nce tus nqi ntawm lysis tsis, nce homogenization thiab lysis lub sijhawm.
A-2 Cov qauv piv txwv loj heev
---- Thov xa mus rau lub peev xwm ua tiav siab tshaj plaws.
A-3 RNA tsis raug tshem tawm ntawm kab ntawv
---- Tom qab ntxiv RNase-Dawb dej, tso nws li ob peb feeb ua ntej centrifuging.
A-4 Ethanol hauv qhov tsim nyog
---- Tom qab yaug, cov centrifuge dua thiab tshem cov tshuaj ntxuav kom ntau li ntau tau.
A-5 Cell kab lis kev cai nruab nrab tsis raug tshem tawm kiag li
---- Thaum khaws cov cell, thov nco ntsoov tshem cov kab lis kev cai nruab nrab kom ntau li ntau tau.
A-6 Cov cell khaws cia hauv RNAstore tsis ua haujlwm zoo
---- RNAstore ntom ntau dua li qhov nruab nrab ntawm kab lis kev cai ntawm tes; yog li lub zog centrifugal yuav tsum tau nce. Nws tau pom zoo kom centrifuge ntawm 3000x g.
A-7 Cov ntsiab lus RNA qis thiab muaj ntau hauv cov qauv
---- Siv qhov piv txwv zoo los txiav txim siab tias qhov txiaj ntsig qis yog tshwm sim los ntawm cov qauv.
A-1 Cov khoom siv tsis tshiab
---- Cov ntaub so ntswg tshiab yuav tsum khaws cia hauv cov kua nitrogen tam sim lossis tam sim muab tso rau hauv RNAstore reagent kom ntseeg tau tias cov txiaj ntsig rho tawm.
A-2 Cov qauv piv txwv loj heev
---- Txo tus nqi qis.
A-3 RNase kev sib kisn
---- Txawm hais tias qhov tsis nyob hauv cov khoom siv tsis muaj RNase, nws yooj yim rau kis RNase thaum lub sijhawm txheej txheem rho tawm thiab yuav tsum tau ua nrog kev saib xyuas.
A-4 Electrophoresis paug
---- Hloov cov electrophoresis tsis thiab ua kom ntseeg tau tias cov khoom siv thiab Loading Tsis pub dawb ntawm RNase paug.
A-5 Kev thauj khoom ntau dhau rau electrophoresis
---- Txo tus nqi ntawm cov qauv thauj khoom, kev thauj khoom ntawm txhua lub qhov dej yuav tsum tsis pub tshaj 2 μg.
A-1 Tus nqi piv txwv loj heev
---- Txo tus nqi qis.
A-2 Qee qhov piv txwv muaj cov ntsiab lus DNA siab thiab tuaj yeem kho nrog DNase.
---- Ua RNase-DNase Kho DNase kom tau txais RNA daws, thiab RNA tuaj yeem siv ncaj qha rau kev sim tom ntej tom qab kho, lossis tuaj yeem ua kom huv ntxiv los ntawm RNA cov khoom siv ua kom huv.
Rau cov iav, ci ntawm 150 ° C rau 4 h. Rau cov ntim yas, raus rau hauv 0.5 M NaOH rau 10 feeb, tom qab ntawd yaug kom huv nrog RNase tsis pub dej thiab tom qab ntawd ua kom tsis huv kom tshem tawm RNase. Cov tshuaj reagents lossis cov kev daws teeb meem siv hauv kev sim, tshwj xeeb tshaj yog dej, yuav tsum tsis pub dawb ntawm RNase. Siv RNase-dawb dej rau txhua qhov kev npaj ua tshuaj reagent (ntxiv dej rau hauv lub khob iav huv, ntxiv DEPC mus rau qhov kawg ntawm 0.1% (V/V), co thaum hmo ntuj thiab autoclave).
