Sample GSM6862397 Query DataSets for GSM6862397
Status Public on Dec 22, 2022
Title Naive1_human_methylation
Sample type SRA
 
Source name PBMC
Organism Homo sapiens
Characteristics tissue: PBMC
cell type: CD8 T cell
Extracted molecule genomic DNA
Extraction protocol Cell sorting was performed by FACS Aria II (BD Biosciences). DNA was extracted using Qiagen RNA/DNA micro allprep columns
DNA was isolated using the AllPrep DNA/RNA Micro kit (Qiagen) and sonicated to generate random 300 to 500-bp fragments. DNA was end-repaired and A-tailed using the Hyper Prep Kit (KAPA Biosystems) following the manufacturer’s protocol. Sequencing adapters that contained fully methylated cytosine residues (Integrated DNA Technologies) were ligated using the Hyper Prep Kit (KAPA Biosystems). Adapter-ligated DNA was bisulfite converted using the EpiTect Bisulfite Kit (Qiagen), with a denaturation time of 10 min. Final libraries were PCR amplified 8–11 times using Tru-seq (Illunima)-compatible custom index primers, as previously described in (Barwick et al., 2016), and HiFi Uracil (KAPA Biosystems). The resulting WGBS libraries were quality checked by Bioanalyzer, pooled at equimolar ratios and sequenced on a NovaSeq S4
 
Library strategy Bisulfite-Seq
Library source genomic
Library selection RANDOM
Instrument model Illumina NovaSeq 6000
 
Description CD8 T cell populations were sorted from human PBMCs, lymph nodes, and tumor.
Data processing Sequenced data was aligned to the human genome using Hisat2 and analyzed using custom R and Python scripts. Fisher’s exact test was used to define regions of statistically (p value less that 1x10-4) differentially methylated CpG motifs. Continuous regions of differentially methylated CpGs were identified by finding regions where at least 6 out of 10 CpGs in a continuous stretch were differentially methylated. These regions were then collapsed and analyzed as single ‘differentially methylated regions’ (DMRs).
