Title |
EA0827: Newcastle Early Arthritis Clinic patient 827 |
Sample type |
genomic |
|
|
Source name |
Rheumatoid Arthritis B cells
|
Organism |
Homo sapiens |
Characteristics |
gender: Female age: 50 tissue: peripheral blood cell type: CD19+ B cells first_diagnosis: Rheumatoid Arthritis working_diagnosis: Rheumatoid Arthritis
|
Growth protocol |
Peripheral blood mononuclear cells first isolated by density centrifugation on Lymphoprep (Axis-Shield Diagnostics, Dundee, UK) underwent positive selection using anti-CD19 magnetic microbeads (Miltenyi Biotec, Bergisch, Gladback, Germany); median cell purity was 96.4% by flow cytometry.
|
Extracted molecule |
genomic DNA |
Extraction protocol |
AllPrep DNA/RNA Mini Kit (Qiagen, UK).
|
Label |
Cy5 and Cy3
|
Label protocol |
Standard Illumina Protocol.
|
|
|
Hybridization protocol |
400ng of DNA was bisulphite-converted and hybridised to the Infinium MethylationEPIC BeadChip (Illumina) using standard Illumina protocol.
|
Scan protocol |
Illumina iScan.
|
Description |
Freshly isolated and purified peripheral blood B cells
|
Data processing |
Failed probes whose detection p-values were >0.01 in >10% samples were excluded prior to functional normalisation as implemented in the minfi R package, following which additional probes were removed due to; (i) cross-hybridization, (ii) mapping to sex chromosomes, or (iii) presence of a SNP (MAF>0.05) at the interrogated CpG, probe sequence or single base extension site. matrix processed value definition: Normalized average Beta values (Functional normalisation)
