title: GSM8262031: WT mice, cerebellum, rep1; Mus musculus; RNA-Seq
library_construction_protocol: Total RNA was extracted by Trizol. RNA library for Strand-specific RNA-seq was prepared as fllows: mRNA was purified  from total RNA using polyT and then fragmented into 300~350 bp fragments, the first strand cDNA was reverse-transcribed using fragmented RNA and dNTPs (dATP, dTTP, dCTP and dGTP) and second strand cDNA was synthesised using DNA polymerase I and dNTPs (dATP, dUTP, dCTP and dGTP). Remaining overhangs of double-strand cDNA were converted into blunt ends via exonuclease/polymerase activities. After adenylation of 3' ends of DNA fragments, sequencing adaptors were ligated to the cDNA and the library fragments were purified. The template without U was enriched by PCR, and the PCR product was purified to obtain the final library.
