One-Step Hot Formamide Extraction Of Rna From Saccharomyces Cerevisiae, Daniel Shedlovskiy, Natalia Shcherbik, Dimitri G Pestov

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

Current methods for isolating RNA from budding yeast require lengthy and laborious steps such as freezing and heating with phenol, homogenization with glass beads, or enzymatic digestion of the cell wall. Here, extraction with a solution of formamide and EDTA was adapted to isolate RNA from whole yeast cells through a rapid and easily scalable procedure that does not require mechanical cell lysis, phenol, or enzymes. RNA extracted with formamide-EDTA can be directly loaded on gels for electrophoretic analysis without alcohol precipitation. A simplified protocol for downstream DNase treatment and reverse transcription reaction is also included. The formamide-EDTA extraction of …
