Sample GSM158656 Query DataSets for GSM158656
Status Public on Mar 10, 2007
Title Normal breast (022_Breast_B)
Sample type RNA
Source name Normal breast epithelium tissue obtained from reduction mammoplasties.
Organism Homo sapiens
Characteristics Normal breast epithelium cells
Extracted molecule total RNA
Extraction protocol Trizol 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
Hybridization protocol Following fragmentation, 15 ug of cRNA were hybridized according to the manufacturer's instructions.
Scan protocol none
Description Normal breast epithelium cells isolated using fluorescence activated cell sorting
Data processing To obtain an expression measure for a given probeset, the mismatch hybridization values were subtracted from the perfect match values, and the average of the middle 50% of these differences was used as the expression measure for the probe set. A quantile normalization procedure was then applied to adjust for differences in the probe intensity distribution across different chips. Specifically, we applied a monotone linear spline to each chip that mapped quantiles 0.01 up to 0.99 (in increments of 0.01) exactly to the corresponding quantiles of a standard chip. The transform log2 [200 + max(X;0)] was then applied.
