Sample GSM7101131 Query DataSets for GSM7101131
Status Public on Mar 17, 2023
Title Naive_day0_D2_AB3060
Sample type genomic
 
Source name Healthy Donor PBMC
Organism Homo sapiens
Characteristics disease state: Healthy
cell type: PBMC
array_id: Hsmb-201959750133-R08C01
biosample: AB3060
donor: D2
cell culture: day0
t-cell subset: Naive
Treatment protocol In some experiments, after purification by cell sorting, a portion of cells were used as starting cells (day 0) and the remaining cells were labeled with CFSE, activated with soluble anti-CD3 (100 ng/ml, eBiosciences) and cultured with the homeostatic cytokines IL-7 and IL-15 (10 ng/ml each, R and D Systems ), for 7 days. Cells from the different subgroups were again sorted, based on CFSE dilution, into non-proliferated and proliferated cells
Growth protocol CD4+ T cells were isolated from elutriated lymphocytes by negative selection using RosetteSep CD4+ T cell enrichment cocktail (StemCell Technologies) followed by Ficoll/Hypaque (Amersham Biosciences) density centrifugation according to the protocol from StemCell Technologies. If necessary, red blood cells were removed using Pharm Lyse (BD Biosciences) according to the manufacturer’s protocol. For staining cells were suspended in 250 μl of Hanks Balanced Salt Solution (HBSS, Mediatech) containing 4% fetal bovine serum (FBS, GeminiBio) and incubated with following antibodies: anti-CD4, anti-CD45RO, and anti-CCR6 for 30 min at room temperature. In some experiments, in addition to these antibodies, cells were incubated with anti-CD25 and anti-CD62L, anti-CXCR5, anti-CXCR3 and anti-CCR4 antibodies. All antibodies were against human antigens. Cells were washed and resuspended in HBSS plus 4% FBS. CD4+ T cells were sorted into CD45RO- (naïve), and CD45RO+ subsets, and the CD45RO+ subset was further separated into CCR6neg, CCR6pos, and, within the CCR6pos cells, into CCR6low, CCR6int and CCR6high subsets. For in vitro polarization experiments, cells were sorted into naïve (CD4+CD45RO-CD25-CXCR5-CCR4-CXCR3-), CCR6neg (CD4+CD45RO+CD25-CXCR5-CXCR3-CCR6- or CD4+CD45RO+CD25-CXCR5- CCR4-CCR6- or CD4+CD45RO+CD25-CXCR5-CXCR3-CCR4-CCR6-), CCR6low (CD4+CD45RO+CD25-CXCR5-CXCR3-CCR6low or CD4+CD45RO+CD25-CXCR5-CCR4-CCR6low or CD4+CD45RO+CD25-CXCR5-CXCR3-CCR4-CCR6low), and CCR6high (CD4+CD45RO+CD25-CXCR5-CXCR3-CCR6high or CD4+CD45RO+CD25-CXCR5-CCR4-CCR6high or CD4+CD45RO+CD25-CXCR5-CXCR3-CCR4-CCR6high). All cell sorting was done using a FACSAria Cell Sorter (BD Biosciences). By post-sort analysis, the purity of populations was 95-99%. Cells were used for experiments immediately after sorting.
Extracted molecule genomic DNA
Extraction protocol DNeasy kit (Qiagen).
Label biotin
Label protocol Bisulfite conversion of genomic DNA (500 ng) was performed using the Zymo Research EZ DNA Methylation kit (Zymo Research) according to the manufacturer’s recommendations for the Illumina Infinium assay. The bisulfite conversion incubation was processed using alternative thermocycler settings as outlined in the “Alternative Incubation Conditions When Using the Illumina Infinium® Methylation” section of the Zymo instruction manual appendix.
 
Hybridization protocol bisulphite converted DNA was amplified, fragmented and hybridised to Illumina Infinium MethylationEPIC v1.0 B1 using standard Illumina protocol
Scan protocol Illumina HiSeq using standard protoocol
Data processing Genome Studio 2011.1
Average Beta (normalized using Genome Studio 2011.1)
