library_construction_protocol: following nuclear run-on, total RNA was isolated by Trizol extraction and biotinylated RNA isolated by streptavidin bead binding follwing hydrolysis of RNA, 3'adaptors were ligated to biotinylated RNA fragments. After 5'Cap removal and end repair, 5' adaptors were also ligated. Adaptor-ligated RNA fragments were reverse transcribed and cDNA libraries amplified using indexed primers.
