| Hybridization protocol |
Equal masses of cDNA from males and females were combined in a 1:3 volume with hybridization buffer (50% formamide, 5X SSC, 0.1% SDS, 10 μg calf thymus DNA) and denatured at 90°C for 4 min, quick chilled, and injected into a Lucidea Slidepro automated hybridization chamber (Amersham) containing a microarray slide pre-hybridized according to manufacturer’s instructions. Following overnight hybridization, slides were washed twice at 60°C in 2X SSC + 0.2% SDS (15 min), once in 0.2X SSC + 0.2% SDS (10 min), once in 0.1X SSC (10 min) and once in 0.5X SSC (10 min). Slides were dipped briefly in 100% isopropanol, centrifuged 5 min at 500 x g to dry, and scanned using an Axon 4200B scanner.
|
| Scan protocol |
Fluorescent array images were collected for both Cy3 and Cy5 with a GenePix 4200B fluorescent scanner and image intensity data were extracted and analyzed with GenePix Pro 5.0 analysis software.
|
| Description |
Four biological replicates (double dye-swaps) were used to assess differences between males and juvenile females under standard laboratory culture conditions.
|
| Data processing |
Data were filtered and extracted using GenePix v. 5.0 and imported in Bioconductor. Normalization for M values was performed using spatial and intensity-dependent lowess smoothing in OLIN and differential expression was assessed using Limma.
