Extracted molecule total RNA
Extraction protocol RNA was extracted from four tissues separately: brain, gill, muscle, and liver. Tissues (10mg) were homogenized in TRI reagent (Ambion) using stainless steel beads on a MM301 mixer mill (Retsch Inc.). Aqueous layer homogenate aliquots (100?L) were transferred to three U-bottom 96 well plates. RNA was extracted from the homogenates using the ÔNo-Spin ProcedureÕ of MagMAX-96 for Microarrays Total RNA Isolation kits (Ambion) and a Biomek NXP automation workstation (Beckman- Coulter). RNA yield and purity were measured by spectrophotometry (A?260 value or A?260/A?280 ratio). RNA extracts were stored in a ?80¡C freezer.
Label Alexa 555
Label protocol RNA extracts were amplified for microarray hybridizations using Amino Allyl MessageAmpª II-96 kits (Ambion). Amplified RNA extracts (5?g, aRNA) were labelled with Alexa dyes using Indirect Labelling kits (Invitrogen). Dye coupling reactions were performed using all aRNA samples with Alexa 555 dye and the reference aRNA (a pool of all samples for a tissue) with Alexa 647.

Hybridization protocol Gene expression was quantified using 44K cGRASP salmonid microarrays (Koop et al., 2008) for each of the four tissues. Fragmented sample and reference cRNA (dye coupled aRNA) in GEx Hybridization HI-RPM buffer (Agilent) were hybridized to microarray slides using aHS4800 Pro Hybridization Station (TecanTrading AG), which automatically washed, hybridized, denatured, and dried the slides. To reduce technical variance, hybridizations were performed by a single technician in batches of up to 48 samples during a two-week period.
Scan protocol Slides were read using a LS Reloaded scanner (TecanTrading AG) and Array- Pro Analyzer software. Images were quantified using ImaGene software (BioDiscovery) with spots being automatically flagged if both dye wavelengths were empty, poor, or negative and manually flagged for reasons such as filaments, blobs, or smears.
Description Sample array position within slide:
Array1Onkism0809_B_10121
raw data files:
Onkism0809_B_10121.txt
Onkism0809_B_10121_ref.txt
sample name in processed data file:
56233
*ref.txt file is the raw data for channel 2 (pooled reference.
Data processing Low quality slides (>50% missing spots or spatial problems) and spots (<2 standard deviations from the mean background at both dye wavelengths) were removed using BASE software (Lund University). Local background correction using background mean and a lowess normalization algorithm were also applied.
The file processed_data_brain_withallcontrols.txt includes normalized log2 background-subtracted intensity ratio (each fish/reference) with 'flagged' spots or poor signals removed for all probes including controls. Sample data tables do not include control probes.
