Sample GSM3223236 Query DataSets for GSM3223236
Status Public on Jul 26, 2019
Title ATAC.d2.FVFp.r1
Sample type SRA
Source name ES cells
Organism Mus musculus
Characteristics cell line: doxycycline (Dox) inducible Foxa2-Venus ES cell line (T119)
genotype/variation: TetON-Foxa2-Venus
facs sorting markers: Venus-positive
time point: d2
antibody: none
Growth protocol ES cells were seeded without feeders in gelatin-coated plates and grown for 48h in ES standard medium (LIF/serum) supplemented with 40ng/ml doxycycline.
Extracted molecule genomic DNA
Extraction protocol ATAC-seq was done as previously described (Buenrostro et al., 2013). Briefly, 50000 FACS sorted cells were washed in 1xPBS, re-suspended in 50 ul of lysis buffer (10 mM Tris pH 7.4, 10 mM NaCl, 3 mM MgCl2, 0.1% NP40,) and spun at 500g for 10 min at 4 °C to collect nuclei. Nuclei were subsequently re-suspended in 50 µl Transposase reaction containing 25µL 2x tagmentation buffer, 22.5 µl water, 2.5 µl Tn5 Transposase (Illumina Nextera DNA Library Preparation Kit, cat. FC-121-1030). Reactions were incubated for 30 min at 37° C in a thermomixer shaking at 300 rpm and DNA purified using Qiagen PCR clean-up MinElute kit (Qiagen).
The transposed DNA was subsequently amplified in 50µl reactions with custom primers as described (Buenrostro et al., 2013). After 4 cycles, libraries were then monitored with qPCR: 5 µl PCR sample in a 15 µl reaction with the same primers. qPCR output was monitored for the ΔRN; 0.25 ΔRN cycle number was used to estimate the number of additional cycles of the PCR reaction needed for the remaining PCR samples. Amplified libraries were purified with the Qiagen PCR clean-up MinElute kit (Qiagen) and size selected for fragments less than 600 bp using the Agencourt AMPure XP beads (Beckman Coulter). Libraries were quality controlled by Qubit and Agilent DNA Bioanalyzer analysis.
