SRX7261959 GSM4201343 SRP234526 SRS5757518 GSM4201343 RNA-Seq TRANSCRIPTOMIC cDNA The cerebral cortex was dissected and homogenized and tagged polysomes were immunopurified with monoclonal anti-EGFP antibodies bound to biotinylated-Protein L (Thermo Fisher) coated streptavidin-conjugated magnetic beads (Life Technologies). Total RNA from IPs was purified with the Agilent Nanoprep kit following manufacturer's protocol. Ribosomal-bound RNA was extracted and treated as described in PMID 24810037, Heiman M, Kulicke R, Fenster RJ, Greengard P, Heintz N. (2014) Cell type-specific mRNA purification by translating ribosome affinity purification (TRAP).
