GSM7098848: intestinal tissue exosomes,S4(sham),rep3; Mus musculus; ncRNA-Seq
The total RNA of exosomes was extracted using the TRIzol method, and the extracted total RNA was sampled for quality inspection. The Agilent 2100 bioanalyzer was used to analyze the concentration and integrity of RNA. After passing the RNA quality inspection, 10 ng to 20 ng of RNA was digested with RNase R to remove linear RNA and used for library preparation. The RNA was fragmented, the 5' end conversion template was added, and the first strand of cDNA was reverse-transcribed. After the first round of PCR plus the index connector, the ligation product was purified, and the ribosomal cDNA was removed with ZapR and R-probes. The library was amplified by selecting the appropriate number of cycles according to the initial amount. After amplification, the circRNA SEQ library was purified and isolated with magnetic beads. After library quality control, different libraries were pooled according to the requirements for effective concentration and target offline data volume.
