Total RNA isolated from cell culture using RNeasy Midi Kit (Qiagen) according to the manufacturer's instructions.
Label
biotin
Label protocol
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 5 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
Hybridization protocol
Following fragmentation, 10 ug of cRNA were hybridized, washed and stained using the Affymetrix Fluidics Station 400 according to Affymetrix standard procedures
Scan protocol
GeneChips were scanned using the Affymetrix GeneChip Scanner 3000
Description
Gene expression data from cultured breast cancer cell line
Data processing
The data were analyzed with Microarray Suite version 5.0 (MAS 5.0) using Affymetrix default analysis settings and global scaling as normalization method. The trimmed mean target intensity of each array was arbitrarily set to 1500.
