## Methods

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.
