Single‐step Method of Total RNA Isolation by Guanidine–Phenol Extraction

The single-step method isolates total RNA from a variety of sources including tissues and cells from human, animal, plant, yeast, bacterial and viral origins. The method is based on liquid-phase separation resulting in sequestration of pure RNA into the aqueous phase. RNA is precipitated from the aqueous phase, dissolved, reprecipitated and washed with alcohol. The entire procedure can be completed in less than 4 h.

Keywords: ribonucleic acid; single-step method; liquid-phase separation; total RNA isolation
