| Sample type |
SRA |

|
| Source name |
MRC-5 cells
|
| Organisms |
Homo sapiens; Human betaherpesvirus 5 |
| Characteristics |
cell line: MRC-5 cells
infection: TB40/E wtGFP strain of HCMV
treatment: infected, 24 hpi
chip antibody: Acetyl-Histone H3 (Lys27) (D5E4) XP Rabbit mAb #8173 (Cell Signaling Technologies)
|
| Treatment protocol |
For each infection, 5x10^6 MRC5 were seeded in 15 cm dishes the day before the infection. The following day, medium was replaced with 10ml of DMEM supplemented with 10% FBS without antibiotics. Confluent MRC5 were infected with HCMV at a multiplicity of infection (MOI) of 2 with TB40/Ewt-GFP. After 1-hour incubation at 37°C, 10 ml of media without antibiotics were added to the plate and the cells incubated at 37°C for 23 hours. Cells were collected at 24hpi.
|
| Growth protocol |
HCMV MRC5 infected with TB40/Ewt-GFP were kept in DMEM medium (Gibco) supplemented with 10% fetal bovine serum (Corning), and 1,000 Units/ml Penicillin-Streptomycin (Gibco) at 37°C in a humidified incubator at 5% CO2.

| Extraction protocol |
After fixation, cells were lysed and sonication with a Bioruptor Plus sonication device (Diagenode). Sonication was conducted for 25 cycles, with 30 sec on/off at high intensity. ChIP was performed by incubating the sonicated sample with either Rpb1 NTD (D8L4Y) Rabbit mAb #14958 or Acetyl-Histone H3 (Lys27) (D5E4) XP Rabbit mAb #8173 (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 Illumina Chip-SEQ Kit multiplexed with IDT unique dual index barcodes. Library quality control was assessed using Bioanalyzer High Sensitivity DNA Analysis kit (Agilent) and sequenced on an Illumina NovaSEQ6000 (100bp paired-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 deepTools
