Sample GSM7178021 Query DataSets for GSM7178021
Status Public on Aug 07, 2023
Title swi3E815X_DTT_R2_input
Sample type SRA
 
Source name W303
Organism Saccharomyces cerevisiae
Characteristics antibody: none
strain: W303
genotype: swi3[delta]; swi3-E815X::LEU2; SNF2-3V5::HISMX
treatment: input. Cells grown in YPD to late-log phase, treated with 5 mM DTT for 1 hour, and fixed in 1% formaldehyde.
Treatment protocol Spike-in cells from an SK1 strain harboring a SNF2-3V5 allele were added at a ratio of 1:5 to each sample prior to immunoprecipitation. IP samples were immunoprecipitated using anti-V5 agarose beads (see Morse et al., 2023 materials and methods for details).
Growth protocol Cells were grown in YPD to late-log phase and split into two flasks. One flask was untreated and the other treated with 5 mM DTT. Two biological replicates were collected 1 hour post-treatment. Replicates were collected on separate days.
Extracted molecule genomic DNA
Extraction protocol Cells were fixed in 1% formaldehyde, lysed in FA lysis buffer with beadbeating, chromatin was extracted by fractionation and sheared using a Bioruptor Pico (see Morse et al., 2023 materials and methods for further details).
DNA libraries were prepared using a NEXTflex Rapid DNA-Seq Kit 2.0 bundle.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NovaSeq 6000
 
Data processing Spike in normalization was performed according to SNP-ChIP pipeline from Vale-Silva et al., 2019
reads were aligned to the sacCer3 reference genome using Bowtie
MACS2 was used to generate bedGraph files for ChIP samples normalized to input
bedGraph files were adjusted by multiplying read depth at each position with the calculated SNP-ChIP normalization factor for each sample
Spike-in adjusted, normalized bedGraph files were converted to BigWig files using deeptools
Assembly: sacCer3 (R64)
Supplementary files format and content: BigWig (.bw) files scaled using SNP-ChIP spike-in normalization for visualization in IGV
