Sample GSM2683281 Query DataSets for GSM2683281
Status Public on Sep 13, 2017
Title RNA-seq for Ptbp2-KO mouse, E18.5 brain cortex, replicate 3
Sample type SRA
 
Source name brain cortex
Organism Mus musculus
Characteristics sample type: replicate 3
genotype/variation: Ptbp2-KO
age: E18.5
tissue: brain cortex
Treatment protocol To activate microglia, adult wildtype B6 mice received daily intraperitoneally injection of 1mg/Kg lipopolysaccharide (L4524, Sigma) or phosphate-buffered saline for 4 consecutive days before sacrifice.
Extracted molecule total RNA
Extraction protocol For Ptbp2-KO brain cortex RNA-seq, E18.5 mouse cortex RNA (three biological replicates) from Ptbp2-KO mice (Licatalosi et al., 2012) was prepared using Trizol (Ambion); ribosomal RNA was removed from 1 μg RNA using Ribo-Zero rRNA removal Kit (Illumina). For microglia isolation, mice were perfused with 30ml of heparinized PBS. Brains were excised, minced and two brains were placed into C tube and processed as per instructions for the Neural Tissue Dissociation Kit P (Miltenyi Biotec) using the gentleMACS Octo Dissociator with Heaters (Miltenyi Biotec, protocol 37_ABDK). Once digested, the debris and myelin was removed using the Debris Removal Solution (Miltenyi Biotec) followed by CD11b positive selection using Microglia CD11b beads (Miltenyi). Cells were counted, washed in PBS and pelleted prior to isolation of RNA. Total RNA from isolated microglia was prepared using Trizol (Ambion) and High Pure RNA Isolation Kit (Roche). The Total RNA was then further purified for polyadenylated RNA by using 150ng Total RNA in Dynabeads mRNA Purification Kit (Ambion).
RNA-seq libraries were prepared using TruSeq RNA Sample Preparation Kit v2 (Illumina) following manufacturer’s instructions.
