WebRNase-free glycogen (Roche, San Francisco, CA, USA) and 600 L of 100% isopropanol were added to the aqueous phase, and the mixture was incubated at room temperature for 10min, then centrifuged at 12,000g for 10min at 4 C. Next, the supernatant was removed from the tube, leaving only the RNA pellet and the RNA wash procedure continued. Finally, the WebExtracted total RNA was treated with Ambion™ DNase I (RNase free) (ThermoFisher Scientific, Vilnius, Lithuania) in the presence of the 10 x DNase Buffer and incubated at 37°C for 30 min. DNase I was inactivated by 2 min incubation with DNase Inactivation Reagent from the DNA-free™ DNA Removal Kit (ThermoFisher Scientific, Vilnius, Lithuania).
