RNA (from a commercial source) from 11 tissues were hybridized to Affymetrix Human Exon 1.0 ST arrays. For each tissue, 3 replicate experiments were done for a total of 33 arrays. The arrays' raw signal intensity was normalized with a quantile normalization method, then run through the PLIER algorithm. The normalized data were then converted to log-ratios, which are displayed as green for negative log-ratios (underexpression), and red for positive (overexpression).
The probe set for this microarray track can be displayed by turning on the Affy HuEx 1.0 track.
\The data for this track was provided and analyzed by Chuck Sugnet at Affymetrix.
