Fragmentation of the ligated samples by alkaline hydrolysis followed by a size selection after electrophoresis on a polyacrylamide gel allowed for the final DNA library to contain inserts of a narrow range. cDNA synthesis by reverse transcription (SuperScriptsIII (Invitrogen)) was performed with a long 5’ phosohorylated primer split by two 18 carbon spacers. Circularization of the RT product was performed with CircLigase (Epicentre) according to the manufacturer’s directions. The PCR was performed directly on the circularized product resulting in DNA with Illumina cluster generation sequences on each end and a sequencing primer binding site positioned so that sequencing would start at the 3’ end.
