RNAlater yog cov kua uas tsis muaj tshuaj lom tsiaj cov ntaub so ntswg preservation reagent.Nws tuaj yeem nkag mus rau hauv cov ntaub so ntswg sai sai thiab tiv thaiv cov cellular tsis khov RNA los ntawm kev puas tsuaj los ntawm kev ua haujlwm zoo inhibiting RNase, yog li tom qab tau txais cov qauv ntaub so ntswg, nws tsis tas yuav ua cov qauv tam sim, thiab tsis tas yuav khov cov qauv hauv cov kua nitrogen., yog linws yooj yim dua rau kev sim tom ntej.Kev siv cov ntaub so ntswg RNA tiv thaiv kev daws teeb meem tuaj yeem zam qhov tsis yooj yim ntawm kev siv cov kua nitrogen los yog cov tub yees txias txias, thiab khaws cov khoom sib txawv ntawm cov ntaub so ntswg hauv cov tshuaj tiv thaiv tuaj yeem nres tam sim thiab txhim kho cov kev hloov pauv ntawm RNA qhia, uas tuaj yeem txo qhov yuam kev ntawm pawg sim.

RNAlater tuaj yeem siv dav hauv ntau cov qauv vertebrate, suav nrog lub hlwb, lub plawv, lub raum, tus po, lub siab, thiab lub ntsws.Tom qab cov ntaub so ntswg tshiab tsis khov rau hauv Buffer RNAlater ntawm qhov sib piv ntawm 1:10, cov qauv tuaj yeem khaws cia hauv chav sov li 1 lub lis piam, 37 ° C rau 1 hnub, 4 ° C rau tsawg kawg 1 lub hlis;Cov ntaub so ntswg tuaj yeem tso rau ntawm 4 ° C ntawm -20 ° C lossissrub ntawm -80 ℃ rau lub sijhawm ntev.
