Sample GSM843281 Query DataSets for GSM843281
Status Public on Jan 26, 2012
Title Subject 012 EDTA, biological rep2
Sample type RNA
 
Source name Post
Organism Homo sapiens
Characteristics gender: M
age: 23
site: McM
allergen: Cat
mch pc20 (mg/ml) at pre-challenge: 10.9
mch pc20 (mg/ml) at post-challenge: 4.25
% fall in fev1 (early): -31.4
% fall in fev1 (late): -15.1
rna integrity number: 4.8
tissue: whole blood
Extracted molecule total RNA
Extraction protocol Samples were stored at -80⁰C until RNA extraction
From PAXgene tube samples, total RNA was purified from 2.5 mL of whole blood using Rneasy mini kit (Qiagen, Chatsworth, CA, USA)
From EDTA tube samples, total RNA was purified from 3.0 mL of whole blood following modified TRIzol-based extraction method.
The yield and quality of RNA was assessed by NanoDrop 8000 Spectrophotometer (Thermo Scientific, Wilmington, DE, USA) and Agilent 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA, USA)
Label biotin
Label protocol standand Affymetrix protocol
 
Hybridization protocol Affymetrix Human Gene 1.0 ST array (Affymetrix, Santa Clara, CA)
Scan protocol standand Affymetrix protocol
Data processing Raw data normalization using the 'farms' package consisted of quantile normalization and summarization of probe-level data.
Data filtering was also performed using the Informative vs. Non-Informative Calls function in the 'farms' package. Differential gene expression was determined using moderated t-tests in limma using an FDR cut-off of 5%.
All statistical analyses were performed in the statistical computing program R.
