Sample GSM1974370 Query DataSets for GSM1974370
Status Public on Dec 18, 2015
Title no OE replicate 2 IP (control for RNR3 OE IP)
Sample type SRA
 
Source name no OE IP (control for RNR3 OE IP)
Organism Saccharomyces cerevisiae
Characteristics genotype/variation: no OE (WT)
drug: Hydroxyurea
time point: HU arrest (60 min post release)
barcode (5'): BC2
chip antibody: BrdU antibody (Invitrogen, catalog#033900)
Treatment protocol Cells were blocked in G1 by resuspension (at O.D. ~0.5) in fresh YEP+2% raffinose +7.5 nM α-factor at 25°C for 3 hrs. For induction, cells were resuspended in YEP+2% galactose +7.5 nM α-factor at 25°C for 2 hrs. Cultures were released into S-phase by resuspension (at O.D. ~1.0) in fresh YEP+2% galactose +200 µg/mL Pronase E (Sigma-Aldrich, P5147) and sonicated to disperse cells. Early S-phase analysis of replication was performed by including 0.2M HU (Sigma-Aldrich, H8627) and BrdU at 400 µg/mL (Sigma-Aldrich, B5002) for 60 min at 25°C. For the time course experiment, BrdU was used at 800 µg/mL.
Growth protocol For late G1 block, induction, and release, cells (pre-selected on SD-URA for plasmid as appropriate) were inoculated into YEP+2% raffinose at 25°C and grown to mid-log phase
Extracted molecule genomic DNA
Extraction protocol Genomic DNA was isolated with standard phenol chloroform extraction
Genomic DNA isolation and shearing by sonication has been described previously (Knott et al., 2012) 1 µg total genomic DNA (sheared to ~300 bp average) was end-repaired and ligated with a barcoded, Illumina-compatible adapter using NEBNext Ultra End Repair/dA-Tailing Module (E7442) and NEBNext Ultra Ligation Module (E7445) (Dunham and Friesen, 2013). AMPure beads (Beckman Coulter Cat#A63880) were used to isolate the genomic DNA and its concentration was determined by spectroscopy (Nanodrop). Equal amounts of multiple such barcoded DNA samples were pooled; 20 ng was set aside as “Input” and 1 µg of this pool was subject to BrdU-IP as described previously (Knott et al., 2012). The IP and Input DNA samples were PCR-amplified separately with indexed Illumina-compatible primers. Amplified DNA was isolated using AMPure beads and validated and quantified on a Bioanalyzer, and pooled.

Description BrdU labeled genomic DNA immunoprecipitated from galactose induced culture arrested in early S-phase
processed data file: RNR_HU.txt
Data processing library strategy: Quantitative BrdU-IP Seq (QBU)
fastq-multx by ea-utils was used to split barcodes (QBU_501_305_swap.txt)
Barcode split PE files were aligned to S. cerevisiae reference genome R64-1-1 using Bowtie2
Aligned files were sorted and binned into 50 bp non-overlapping bins using Samtools/Bedtools (QBU_HU.txt)
For QBU samples, IP bins were divided by their corresponding Input (Total) Sample Bins to yield normalized data (QBU_Time_Course.txt)
