title: GSM4220031: M7; Rattus norvegicus; miRNA-Seq
library_construction_protocol: Total RNA was isolated from hippocampi using the Trizol (invitrogen) according to the manufacturer's protocol. RNA purity was assessed using the ND-1000 Nanodrop. Each RNA sample had an A260:A280 ratio above 1.8 and A260:A230 ratio above 2.0. RNAs were ligated with 3'RNA adapter, and followed by 5'adapter ligation. Subsequently, the adapter-ligated RNAs were subjected to RT-PCR and amplified with a low-cycle. Then the PCR products were size selected by PAGE gel according to instructions of NEBNext® Multiplex Small RNA Library Prep Set for Illumina® (Illumina, USA).
