31_A2P032_SIV_CD8N ATAC |
| Sample type |
SRA |
| |
|
| Source name |
peripheral blood
|
| Organism |
Macaca nemestrina |
| Characteristics |
tissue: peripheral blood
cell type: CD8 naiveT cell
disease state: SIV
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Up to 10,000 sorted cells from each population were pelleted and resuspended in 2x Tagmentation Buffer (Illumina), 0.02% Digitonin, and 0.1% Tween-20, with Tagment DNA TDE1 Enzyme (Illumina) and incubating at 37°C for one hour. The mix was then incubated with proteinase K for 30 minutes at 40°C.
High molecular weight DNA was removed with a 0.7x selection ratio of Agencourt AMPureXP beads (Beckman Coulter) and low molecular weight DNA was isolated from the remainder with a 1.2x selection ratio. Library amplification was performed with KAPA HiFi HotStart ReadyMix (KAPA) and i5 and i7 indexing primers (Nextera DNA CD Indexes) for 11-15 total cycles depending on the sample concentration reached after 5 cycles (KAPA Library Quantification kit). Library DNA was purified with a 1x selection ratio of AMPureXP beads. The final library was verified by High Sensitivity DNA Bioanalyzer (Agilent).

| Description |
31_A2P032_SIV_CD8N
|
| Data processing |
ATAC-seq samples were sequenced as 151bp paired-end libraries on a Novaseq S4. All samples had over ?? million reads.
Samples were trimmed for adapters using Cutadapt v 1.18 before alignment. The trimmed reads were aligned to the RheMac10 reference using Bowtie2 v2.3.4.1 with flag -k 10.
Assembly: RheMac10
Supplementary files format and content: The peaks were called using Genrich v0.6 with the following flags -j -y -r -v -d 150 -m 5 -e chrM,chrY.
Supplementary files format and content: Genrich-produced bedgraphs were normalized by library size (reads per million sequenced reads, RPM) for visualization.
