A subset (3 samples from each group) of samples were pooled (see spreadsheet, green-highlighted samples), each providing ~7.5ug of RNA, yielding 112.17uL. 0.1 vols of 3M NaOAC, pH = 5.2 were added to the tube (11.22uL). 2 vols of EtOH (246.8uL) was added to the tube. Tube was vortexed to mix and incubated @ -20C O/N.
