Solublization of RNA in Formamidecontributed by James McCaughern-Carucci, Yale University Resuspending RNA in Formamide (as reported by Chomczynski et al. Nucleic Acids Research) has several benefits over storage in water or ethanol. First, formamide will protect RNA from RNases. The RNA is also extremely stable, allowing it to be stored overnight at 4C, or indefinitely at -20C. Samples can even be left at room temperature overnight without fear of degradation. Samples can be made to be highly concentrated, up to 4 mg/ml. Finally, with concentrated samples, no drying of your RNA is necessa
