Query DataSets for GSM6345762

Status

Public on Oct 03, 2023

Title

ZNF611.

Sample type

SRA

Source name

Naïve WIBR3 overexpressing ZNF611

Organism

Homo sapiens

Characteristics

genotype/variation: WIBR3 hESC
antibody: HA

Treatment protocol

Primed H1 were transduced with GFP or KLF4-containing lentiviral vectors and split after 48h then selected using blasticydin for the 3 following days. Naïve WIBR3dPE hESC cells in KN/2iL media were transduced with GFP or ZNF611-containing lentiviral vectors, split after 96h, then selected for a couple of passages with blasticydin on irradiated Mouse Embryonic Blasticidin-resistant (MMMbz).

Growth protocol

4i media
Conventional (primed) human ESC lines were maintained in mTSER for H1 (Male)on Matrigel, for WIBR3 (Female) on irradiated inactivated mouse embryonic fibroblast (MEF) feeders in human ESC medium (hESM) and passaged with collagenase and dispase, followed by sequential sedimentation steps in hESM to remove single cells while naïve ES cells and primed H1 were passaged by Accutase in single cells. hES media composition: DMEM/F12 supplemented with 15% fetalbovine serum, 5% KnockOut Serum Replacement, 2 mM L-glutamine, 1% nonessential amino acids, 1% penicillin-streptomycin (Lonza), 0.1 mM β-mercaptoethanol and 4 ng/ml FGF2. Naïve media composition: 500 mL of medium was generated by including: 240 mL DMEM/F12, 240 mL Neurobasal, 5 mL N2 supplement, 10 mL B27 supplement, 2 mM L-glutamine, 1% nonessential amino acids, 0.1 mM β-mercaptoethanol, 1% penicillin-streptomycin, 50 μg/ml BSA. In addition for KN/2i media: PD0325901 (1 μM), CHIR99021 (1 μM), 20 ng/ml hLIF and Doxycycline (2 µg/ml).

genomic DNA

Extraction protocol

Cells were cross-linked for 10 minutes at room temperature by the addition of one-tenth of the volume of 11% formaldehyde solution to the PBS followed by quenching with glycine. Cells were washed twice with PBS, then the supernatant was aspirated and the cell pellet was conserved in -80°C. Pellets were lysed, resuspended in 1mL of LB1 on ice for 10 min (50 mM HEPES-KOH pH 7.4, 140 mM NaCl, 1 mM EDTA, 0.5 mM EGTA, 10% Glycerol, 0.5% NP40, 0.25% Tx100, protease inhibitors), then after centrifugation resuspend in LB2 on ice for 10 min (10 mM Tris pH 8.0, 200 mM NaCl, 1 mM EDTA, 0.5 mM EGTA and protease inhibitors). After centrifugation, resuspend in LB3 (10 mM Tris pH 8.0, 200 mM NaCl, 1 mM EDTA, 0.5 mM EGTA, 0.1% NaDOC, 0.1% SDS and protease inhibitors) for histone marks and SDS shearing buffer (10 mM Tris pH8, EDTA 1mM, SDS 0.15% and protease inhibitors) for transcription factor and sonicated (Covaris settings: 5% duty, 200 cycle, 140 PIP, 20 min), yielding genomic DNA fragments with a bulk size of 100-300bp. Coating of the beads with the specific antibody and carried out during the day at 4°C, then chromatin was added overnight at 4°C for histone marks while antibody for transcription factor is incubated with chromatin first with 1% Triton and 150mM NaCl. Subsequently, washes were performed with 2x Low Salt Wash Buffer (10 mM Tris pH 8, 1 mM EDTA, 150mM NaCl, 0.15% SDS), 1x High Salt Wash Buffer (10 mM Tris pH 8, 1 mM EDTA, 500 mM NaCl, 0.15% SDS), 1x LiCl buffer (10 mM Tris pH 8, 1 mM EDTA, 0.5 mM EGTA, 250 mM LiCl, 1% NP40, 1% NaDOC) and 1 with TE buffer. Final DNA was purified with Qiagen Elute Column. Up to 10 nanograms of ChIPed DNA or input DNA (Input) were prepared for sequencing. Library was quality checked by DNA high sensitivity chip (Agilent). Quality controlled samples were then quantified by picogreen (Qubit® 2.0 Fluorometer, Invitrogen). Cluster amplification and following sequencing steps strictly followed the Illumina standard protocol. Libraries were ligated with Illumina adaptors
Illumina HiSeq 2500 (Illumina), with each library sequenced in 100-bp reads run.
