Sample GSM3908268 Query DataSets for GSM3908268
Status Public on Dec 31, 2021
Title G1E-R307C_ATAC_rep2
Sample type SRA
Source name cell line
Organism Mus musculus
Characteristics cell line: G1E
vector: R307C
genotype: GATA1 point mutant p.R307C
Treatment protocol n/a
Growth protocol IMDM, 15% FBS, 1xPen/Strep, 4.5E-5M mono-thio-glycerate, 50ng/ml murine SCF and 2U/ml erythropoietin
Extracted molecule genomic DNA
Extraction protocol After washing with PBS, around 10,000 cells were lysed and tagmented in 1x TD buffer, 2.5 µl Tn5 (Illumina), 0.1% NP40, 0.3x PBS in a 50 µl reaction volume. Samples were incubated at 37C for 30 min at 300 rpm. Tagmented DNA was purified using the MinElute PCR kit (Qiagen). The complete eluate underwent PCR, as follows. After initial extension, 5 cycles of pre-amplification using indexed primers and NEBNext® High-Fidelity 2X PCR Master Mix (NEB) were conducted, before the number of additional cycles was assessed by quantitative PCR using SYBR Green. Typically, 7-9 additional cycles were run. The final library was purified using a MinElute PCR kit (Qiagen) and quantified using a Qubit dsDNA HS Assay kit (Invitrogen) and a High Sensitivity DNA chip run on a Bioanalyzer 2100 system (Agilent).
Library strategy ATAC-seq
Library source genomic
Library selection other
Instrument model Illumina NextSeq 500
Data processing Raw sequencing data was processed using bcl2fastq
Paired-end reads were aligned to the mm10 reference genome using bowtie2
Duplicate reads were removed using Picard and peaks were called with macs2. A consensus peak file was generated using a strategy discussed in the DiffBind workflow.
