In vitro storage tests. Evaluation of the nucleic acid recovery efficiency and stability after 3 months storage period using the FastPrep co-extraction protocol. a Comparison of the recovery efficiency of the six methods preserving the samples prior nucleic acid extraction. b Evolution of the nucleic acid recovery efficiency over time of the preserved samples prior nucleic acid extraction. Both DNA and RNA stability rapidly decline in all the storing methods, with the liquid nitrogen the best option preserving samples for DNA extraction. c Stability over time of the extracted RNA stored in RNAStable at room temperature. The solution preserved virtually intact the extracted RNA over the 3-month storage period
