Qiagen RNeasy Fibrous Tissue Mini Kit 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 from 2 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
Hybridization protocol
Following fragmentation, 10 ug of cRNA were hybridized for 16 hr at 45C on HGU133 Plus 2.0 Array. GeneChips were washed and stained in an Affymetrix Fluidics Station 450.
Scan protocol
GeneChips were scanned using the Affymetrix GeneChip Scanner 3000 7G.
