Storage of RNA
For short-term storage, resuspend RNA and store at -20°C. For long-term storage, store at -80°C. Store RNA resuspended in water or buffer at -80°C. However, at -80°C, RNA is most stable in an NH4OAc/ethanol precipitation mixture. We recommend aliquotting RNA solutions into several tubes. RNA stored in aliquots will prevent damage to the RNA from successive freeze-thaw events and help prevent accidental RNase contamination. Finally, for optimal long-term storage, RNA oligonucleotides should be dried.
