| Sample type |
SRA |

|
| Source name |
H3K27me3_24hpi
|
| Organism |
Human betaherpesvirus 5 |
| Characteristics |
treatment: HCMV infected, 24 hr
chip antibody: Tri-Methyl-Histone H3 (Lys27) (C36B11) Rabbit mAb #9733 (Cell Signaling Technologies)
cell line: Kasumi-3
|
| Treatment protocol |
Kasumi-3 were infected with TB40/E wtGFP strain of HCMV at MOI 1. Extracellular virus was inactivated at 4 hours post infection. Cells were either collected and fixed immediately (4hpi) or left in culture for additional 24 hours.
|
| Growth protocol |
Kasumi-3 were grown in RPMI-1640 medium (ATCC 30-2001) supplemented with 20% fetal bovine serum (Corning) and 1,000 Units/ml Penicillin-Streptomycin (Gibco)
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
After fixation, cells were lysed and sonication with Covaris Focused-ultrasonicator at 10% Duty Cycle, 140 peak, 200 cycles per burst, 360 seconds. ChIP was performed by incubating the sonicated sample with either Rpb1 NTD (D8L4Y) Rabbit mAb #14958, Acetyl-Histone H3 (Lys27) (D5E4) XP Rabbit mAb #8173, or Tri-Methyl-Histone H3 (Lys27) (C36B11) Rabbit mAb #9733 (Cell Signaling Technologies) and the protein A/G agarose beads. Beads were washed and eluted in 200μl of elution buffer (50 mM Tris-HCl at pH 8.0, 10 mM EDTA, 1.0% SDS). The eluates were de-cross-linked and the DNA purified using the Qiagen PCR purification kit.
Libraries were prepared with the KAPA HTP Library Preparation Kit multiplexed with NEXTflex DNA Barcodes (Bio Scientific) and size selected with AMPure XB beads (Beckman Coulter) to have fragments 250-450 bp in length. Library quality control was assessed using Bioanalyzer High Sensitivity DNA Analysis kit (Agilent) and sequencing was performed with Illumina NextSeq technology (50bp single- end reads).

Adapters were trimmed from reads using cutadapt version 1.13
Trimmed reads were aligned to the reference genome using Bowtie2 version 2.2.6
bigWig files were created using HOMER
