Sample GSM4453431 Query DataSets for GSM4453431
Status Public on Apr 04, 2020
Title ura3FLAGlog_IP
Sample type SRA
 
Source name archaeal cells
Organism Halobacterium salinarum
Characteristics strain: AKS113
genotype: [delta]ura3 cdrL::FLAG
growth phase: logarithmic
epitope tag: FLAG
antibody: anti-FLAG (Abcam ab1162) anti-rabbit monoclonal antibody
Treatment protocol Cells were crosslinked and immunopreciptated with FLAG antibody as described in Wilbanks et al., 2012 (doi: 10.1093/nar/gks063) with the following exceptions: cultures were crosslinked and immuniprecipitated as described (Wilbanks et al., 2012) with the following exceptions: cultures were crosslinked with 1% formaldehyde for 30 minutes at room temperature; immuoprecipitations were conducted using Dynabead magnetic beads (Thermo-Fisher product 10002D) conjugated with anti-FLAG (Abcam ab1162) anti-rabbit monoclonal antibody at 1:250 dilution. DNA concentration was determined by Nanodrop (Thermo Scientific).
Growth protocol Triplicate cultures of strains AKS113 (CdrL tagged at the C-terminus with the FLAG epitope, Supplementary Table 4) and ∆ura3 control strain were grown until stationary phase and subcultured in rich media supplemented with 50 µg/ml uracil. At mid-log phase (OD600 ~0.15) and early stationary phase (OD600 ~1.8), cultures were crosslinked and immunoprecipitated.
Extracted molecule genomic DNA
Extraction protocol Libraries were constructed using the KAPA Hyper Prep kit and Illumina TruSeq adapters according to manufactuer's instructions. DNA library quality was assessed by Bioanalyzer using a High Sensitivity DNA chip (Agilent). Samples were pooled and run in a single lane on an Illumina HiSeq 4000 (Duke Sequencing and Genomics Technologies core).
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 4000
 
Description DNA immunopreciptated control with no epitope tag
HBT-ura3-cdrL-log-pks.bed
Data processing 50 bp single reads were assessed for quality using FastQC (www.bioinformatics.babraham.ac.uk)
adapter sequences trimmed using Trim Galore (www.bioinformatics.babraham.ac.uk) and Cutadapt
Resultant sequences were aligned to H. salinarum NRC-1 genome (RefSeq: NC_002607.1, NC_002608.1, NC_001869.1) using Bowtie2
Peaks were called using MOSAiCS with arguments: fragment length 200, bin size 200, read capping 0, analysis type IO, background estimate rMOM, signal model 2S, FDR 0.01.
Genome_build: GCF_000006805.1_ASM680v1
Supplementary_files_format_and_content: wig files were generated using the "generateWig()" command in the R MOSAiCs package; bed files were generated from peak calling with MOSAiCs
