Sample GSM3518972 Query DataSets for GSM3518972
Status Public on Sep 19, 2019
Title CE-2: Cardioembolic_pool2
Sample type RNA
 
Source name Blood buffy coat, CE
Organism Homo sapiens
Characteristics diagnosis: ischemic stroke
tissue: blood
# pooled samples: 2
average age: 78
Treatment protocol Blood samples were collected into EDTA tubes within 4.5 hours from stroke onset. Buffy coat was collected after centrifugation at 1500 g, 4°C for 15 minutes and mixed with RNAlater solution (Ambion).
Growth protocol Blood buffy coat samples were frozen at -80°C until RNA isolation.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated with the RiboPure-Blood kit (Ambion) and depleted with the GLOBINclear kit (Ambion)
Label biotin
Label protocol Samples were amplified with Ovation Pico WTA kit (Nugen) and fragmented and labeled with Encore Biotin Module (Nugen).
 
Hybridization protocol cDNA was hybridized in GeneChip Human Exon 1.0 ST arrays Affymetrix microarrays for 16 hours with rotation
Scan protocol Microarrays were scanned in Affymetrix Genechip Scanner 3000
Description Gene expression data from blood samples 4.5 hours after ischemic stroke
Data processing The images were processed with the Affymetrix GeneChip Command Console software (Affymetrix) for CEL file generation. To check the array quality, Affymetrix Expression Console was used. Samples that demonstrated good quality results (pm mean, bgrd mean, pos vs neg auc, ...) were subjected to subsequent analysis. Raw expression values obtained directly from .CEL files were preprocessed using the RMA method. Statistical language R and Bioconductor associated packages were used to process data.
