Sample GSM7604305 Query DataSets for GSM7604305
Status Public on Jan 17, 2024
Title Rice K+PDS_rep1
Sample type SRA
 
Source name seedling
Organism Oryza sativa
Characteristics tissue: seedling
antibody: anti-BG4
genotype: WT
treatment: K+PDS G4 stabilizing buffers
Growth protocol temperature of 28–30 °C and a 14 h/10 h light/dark cycle
Extracted molecule genomic DNA
Extraction protocol collected and cut into small slices of 1–1.5 cm in size, followed by cross-linking with a 1% final concentration of formaldehyde for 10 min under vacuum.
DNA immunoprecipitation with anti-BG4 antibody coupled with sequencing termed BG4-DNA-IP-seq. Briefly, 5 μg of fragmented genomic DNA was denatured and reassociated in the G4 stabilization buffer (40% PEG200, 10 mM Tris-HCl, pH 7.5, with 150 mM KCl or NaCl), which was then followed by incubation with anti-BG4-FLAG antibody in the IP incubation buffer (50 mM HEPES, 150 mM KCl, 1 mM MgCl2, 130 nM CaCl2, 1% BSA, 40% PEG200, Complete Mini, pH 7.5). After adding anti-FLAG antibody (D110005, BBI, Shanghai, China) and washed protein G Dynalbeads (10004D, Invitrogen, Carlsbad, CA, USA) for additional 4 h followed by washing two times, anti-BG4 recognized DNA-G4s was finally recovered for library preparation. IPed and input DNA was used for library preparation using the NEBNext®Ultra™ II DNA Library Prep Kit for Illumina (E7645S, NEB). All libraries were sequenced on the Illumina platform.
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina HiSeq 4000
 
Data processing Sequenced reads were trimmed for adaptor sequences using trim_galore
BWA (Burrows-Wheeler Aligner) with default parameters was used to align all cleaned reads to the MSU v7.0 reference genom
MACS was used to call IP-G4 (referred to as G4s pulled down by anti-BG4 antibody) peaks from reads with an alignment length greater than 50.
Assembly: MSU v7.0
Supplementary files format and content: bigWig, narrowPeak (except for Input sample)
Library strategy: BG4-DNA-IP-Seq
