Title |
peripheral blood-Case8_1 |
Sample type |
RNA |
|
|
Source name |
peripheral blood-Case8
|
Organism |
Homo sapiens |
Characteristics |
case/control pair: 8 age at sample (months): 17 time from seroconversion (months): -11.9 time from t1d diagnosis (months): no T1D diagnosis gender: male tissue: peripheral blood hla-dqb1 genotype: 02, 0302
|
Growth protocol |
2.5 ml of venous blood was drawn into PAXgene Blood RNA tubes (PreAnalytix Switzerland), at the Type 1 Diabetes Prediction and Prevention (DIPP) study clinic, Turku, Finland. The samples were incubated for 2 hours at RT and then stored at -70 °C until analyzed.
|
Extracted molecule |
total RNA |
Extraction protocol |
Total whole-blood RNA was extracted from the samples using PAX gene RNA Blood RNA kit (Qiagen, Germany) according to manufacturer's instructions. RNA quality and quantity was determined using Nano Drop ND-1000 (Nano Drop Technologies, USA) and Experion Automated Electrophoresis System (Bio-Rad Laboratories, Finland).
|
Label |
Cy3
|
Label protocol |
100 ng of total RNA was amplified and reverse transcribed with Ovation RNA amplification system v2 (NuGEN, cat. no 3100-60), including Ovation whole blood reagent (cat. no 1300-60). 5 ug cDNA was labeled according to NuGEN’s Illumina solution protocol, application note #2. cDNA concentration and quality was controlled with Experion Automated Electrophoresis System (Bio-Rad Laboratories, Finland).
|
|
|
Hybridization protocol |
1.5 ug each sample was hybridized to Illumina Sentrix Human-6 V2 Expression Bead Chips at 58 °C overnight (18 h) according to Illumina Whole-Genome Gene Expression Direct Hybridization protocol, revision A. Hybridizations were detected with 1 ug/ml Cyanine3-streptavidine (GE Healthcare Biosciences cat. no PA43001).
|
Scan protocol |
Chips were scanned with Illumina Bead Array Reader. Numerical results were extracted with Bead Studio v3.3without any normalization or background subtraction.
|
Data processing |
The intensities were quantile normalized and log2-transformed using R/Bioconductor.
