Sample GSM4082887 Query DataSets for GSM4082887
Status Public on Apr 21, 2021
Title Streaming stage replicate 1
Sample type SRA
 
Source name Streaming cell nuclei
Organism Dictyostelium discoideum
Characteristics developmental stage: Streaming
strain: AX4
Growth protocol We cultured te strain at 22 °C shaken in the incubator at 180 rpm in HL5 medium with 300 μg/ml streptomycin
Extracted molecule genomic DNA
Extraction protocol Frozen pellets of D discoideum cells from the various stages were washed twice with cold PBS and lysed with 10 mM Tris-HCl (pH 7.4), 10 mM NaCl, 3 mM MgCl2, 0.1% Igepal-630
Nuclei were transposed using the Nextera DNA Library Prep Kit.  Transposed libraries were amplified for 11 cycles and size selected for fragments ranging 200-1000 bp. ATAC-seq experiments were sequenced to a minimum depth of 10 million reads/sample.
 
Library strategy ATAC-seq
Library source genomic
Library selection other
Instrument model Illumina NextSeq 500
 
Data processing Real-Time Analysis (RTA) software
The raw fastq files were trimmed for the first and last 8 nucleotides, the multiqc was use to summarize the fastQC results, and the trimmed files were mapped to the Dictyostelium discoideum genome using bowtie2
The mitochondria genome was removed in the alignment process
The duplicated reads were removed by picard and sorted bam files were subject to peak calling with MACS2
Open chromatin regions and peak annotation were deducted with Diffbind and ChIPSeeker, respectively
Genome_build: AX4
Supplementary_files_format_and_content: Peak files for open chromatin regions
