| Title |
NORMAL-605-Cerebellum |
| Sample type |
RNA |
| |
|
| Source name |
normal brain (cerebellum)
|
| Organism |
Homo sapiens |
| Characteristics |
disease state: normal
tissue: cerebellum
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNeasy (Qiagen) extraction of total RNA was performed according to the manufacturer's instructions.
|
| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol (Expression Analysis Technical Manual, 2001, Affymetrix).
|
| |
|
| Hybridization protocol |
Following fragmentation, 11.5 ug of cRNA were hybridized for 16 hr at 45C on GeneChips. GeneChips were washed and stained in the Affymetrix Fluidics Station 450
|
| Scan protocol |
GeneChips were scanned using the Affymetrix Gene Chip Scanner 7G.
|
| Description |
Gene expression data from surgical tumor sample of normal brain
[collection protocol] Tumor samples were snap frozen in liquid nitrogen or transferred to RNAlater immediately after surgical removal as part of patient care. All samples were collected with appropriate IRB approval (COM-IRB#95-500 and 09-0906 )
|
| Data processing |
Microarray .CEL file data was background corrected and normalized using the gcRMA algorithm, resulting in log 2 expression values. The Affymetrix HG-U133 plus 2 microarray contains 54,675 probe sets including multiple probe sets for the same gene. In order to reduce error associated with multiple testing we used only a single probe set for each gene that possessed the highest gcRMA expression level across all our samples. This filtered list of the best expressed probe sets contained 21,050 genes.
