title: GSM1269469: MCF7 total RNA; Homo sapiens; RNA-Seq
library_construction_protocol: Total RNA was extracted using the miRNeasy kit (Qiagen). 4SU residues were biotinylated using EZ-Link biotin-HPDP (Thermo Fisher Scientific). Biotinylated 4SU-labled RNA was separated from non-labeled RNA using μMACS Streptavidin MicroBeads (Miltenyi) and 4SU-labeled RNA was eluted from μColumns by addition of 100 mM DTT. RNA was recovered from the flow-though and 4SU-labeled fractions using MinElute Spin columns (Qiagen). Input (total), flow-though (non-labeled RNA) and eluted (4SU-labled RNA) samples were used for poly(A)+ mRNA library preparation following the TruSeq RNA sample Prep v2 LS protocol (Illumina). The libraries were sequenced on an Illumina HiSeq2500 for 100 cycles (multiplexed 1× 101 + 7 index). mRNA half-lives were computed as previously described (Schwanhausser et al., 2011)
