title: GSM5212896: Mouse brain_rep1_treated; Mus musculus; OTHER
library_construction_protocol: Total RNA was isolated from cell lines or mouse tissues with TRIzol (Invitrogen) according to the manufacture's protocol. The mRNA was isolated by subjecting total RNA to oligo(dT) enrichment using Dynabeads Oligo(dT)25 (NEB) Fragmented RNA was first subjected to end repair by T4 PNK. For the treated sample, the RNA was treated with periodate followed by Endonuclease V cleavage.3′-adapter ligation (3′ adapter, /5rApp/NNNNNNTGGAATTCTCGGGTGCCAAGG/3ddC/) followed by the 3′ adapter removing by 5′-deadenylase and RecJf digestion. After purification, SuperScript III was used to perform RT (RT primer, /ACACGACGCTCTTCCGATCT). After cDNA synthesis, 5′ adapter (5′ adapter, /5Phos/NNNNNNNNNNAGATCGGAAGAGCACACGTCTG/3ddC/) ligation were performed. After purification, qPCR was performed to evaluate the cycle numbers of each samples to avoid over-amplification. Library PCR amplification was performed using the NEB primers. The products were purified by NEBNext Sample Purification Beads or low melting point agarose gel and used for sequencing.
