Sample GSM2549739 Query DataSets for GSM2549739
Status Public on Jun 13, 2018
Title RNA-seq E14 chromatin_1
Sample type SRA
Source name mESCs
Organism Mus musculus
Characteristics cell line: E14 cell line
cell compartment: chromatin
Growth protocol The E14 cell line (mESCs) was cultured at 37 °C, 7.5% CO2, on 0.1% gelatin coated plates, in DMEM + GlutaMax™ (Gibco) with 15% fetal bovine serum (Gibco), MEM non- essential amino acids (Gibco), penicillin/streptomycin (Gibco), 550 µM 2-mercaptoethanol (Gibco), and 10 ng/ml of leukaemia inhibitory factor (LIF) (eBioscience).
Extracted molecule total RNA
Extraction protocol Cell fractionation was performed as described in (Pandya-Jones & Black, RNA, 2009), (Bhatt et al., Cell, 2012) and based on (Wuarin & Schibler, MCB, 1994) with modifications. All subsequent steps have been conducted on ice or at 4°C and in the presence of 25 µM α-amanitin (Sigma, A2263), 50 Units SUPERaseIN (Life Technologies, AM2696) and Protease inhibitors cOmplete (Roche, 11873580001) according to manufacturer’s instructions using RNAse free equipment. All buffers have been pre-chilled on ice before use. The cell pellet corresponding to 1x107 cells was gently resuspended in 200 µl cytoplasmic lysis buffer (0.15% NP-40, 10 mM Tris-HCl pH 7.0, 150 mM NaCl). The cell lysate was incubated for 5 min on ice, layered onto 500 µl sucrose buffer (10 mM Tris-HCl pH 7.0, 150 mM NaCl, 25% sucrose) and centrifuged at 16,000 g for 10 min. The supernatant corresponding to the cytoplasmic fraction was carefully removed.
Sequencing library preparation was performed as described in (Mayer & Churchman, 2016)
