YALEPIC® Tryzol Plus Reagent(No DNase I) is a ready-to-use reagent for the isolation of total RNA from cells and tissues. After centrifugation, the solution is separated into an upper colorless aqueous phase containing RNA and a lower pink organic phase. RNA is precipitated and recovered with isopropanol. Proteins can be recovered from organic phase with isopropanol. Compared with other total RNA extraction reagents, it provides a powerful lysis buffer to extract RNA from a variety of species.
