| Description |
Tumorigenic population (ESA+ CD44+ CD24-/low Lin-) of a breast tumor isolated using fluorescence activated cell sorting. Sample consists of three replicates.
|
| 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.
