POOLING_STRATEGY: none
LIBRARY_CONSTRUCTION_PROTOCOL: Four 痢 of total RNA was extracted from frozen cell pellets using the RNeasy Mini Kit (Qiagen, Valencia, CA). PolyA RNA was isolated from total RNA using Dynabeads oligo(dt)25 (Invitrogen). PolyA selected RNA was eluted in 2x Superscript III buffer supplemented with 10mM DTT and was fragmented by incubation at 94蚓 for 4 minutes. First-strand cDNA was synthesized with the following reaction composition: 0.5 無 random hexamer, 0.5 無 RNase Out, 1 無 DTT (100 mM), 0.5 無 dNTP (25 mM), 0.5 無 SuperScript III (20 無 final). The reaction was incubated at 25蚓 for 10 min then 50蚓 for 50 min. Single-stranded cDNA was isolated by purification with RNAClean XP beads (Beckman Coulter Genomics, Danvers, MA). The dUTP-containing second-strand was synthesized with the following reaction: 1.5 無 NEBuffer 2 (NEB), 1 無 dNTP mix (10 mM dATP, dCTP, dGTP, and dUTP), 0.2 無 RNase H, 1 無 DNA Polymerase I (E. coli) (New England Biolabs) (15 無 final). The reaction was incubated at 16蚓 for 2.5 hours. The dUTP-containing cDNA was isolated by purification with AMPure XP beads (Beckman Coulter Genomics, Danvers, MA). The dUTP-containing cDNA was then end repaired and a 3? A base was added. TruSeq adapters (Illumina, San Diego, CA) were ligated to the dUTP-containing cDNA at 16蚓 for 16 hours with T4 DNA ligase (New England Biolabs). Adapter-ligated cDNA was isolated by two rounds of purification with AMPure XP beads. The dUTP-containing strands were digested at 37蚓 for 30 min with uracil DNA glycosylase (Enzymatics). Adapter-ligated, single-stranded DNA molecules were enriched by 10 cycles of PCR with the following reaction composition: 5 無 TruSeq PCR Primer Cocktail (Illumina), 25 無 TruSeq PCR Master Mix (Illumina) (50 無 final). The thermocycling parameters were: 98蚓 30 sec, then 10-15 cycles of 98蚓 10 sec, 60蚓 30 sec and 72蚓 30 sec, ending with one 72蚓 5 min step. The reaction products were purified using AMPure XP beads.
