Sample preparation
The starting material was wild-type Canton-S adult flies, reared at 22[o]C on a 12:12h light regime, on standard Drosophila diet, 1 week after adult emergence. Tissues were isolated by hand dissection from equal numbers of male and female 7-day old flies (except in the case of gonads). Multiple sample collections were pooled to obtain enough tissue to provide 2 ug of total RNA.
Collection preparation
Total RNA was extracted using RNeasy Micro kit (Invitrogen) according to the manufacturer's instructions. Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 2 ug total RNA.
Mode of assay
Following fragmentation, 10 ug of cRNA (or according to the affy IVT protocol) were hybridized for 16 hr at 45[o]C on GeneChip Drosophila Genome 2 Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 450. GeneChips were scanned using the GeneChip scanner 3000 7G.
Assay platform
Affymetrix_GeneChip_v2
Data analysis
The data were analyzed with GCOS1.4 using Affymetrix default analysis settings and global scaling as normalization method. The trimmed mean target intensity of each array was arbitrarily set to 100. For each tissue, the entire procedure was repeated 4 times, to create 4 independent replicates.

Quantitation of expression at gene level: FlyAtlas provided mean coverage levels for Affy2 probe sets, and FlyBase intersected these probe sets with the exons of all FlyBase genes to associate each probe set with one or more FlyBase genes. These values were distributed into five expression level bins for further analysis.
