| Title |
H27M_rep1_Array2 |
| Sample type |
RNA |
| |
|
| Source name |
whole body, 7-day-old adult, male
|
| Organism |
Drosophila persimilis x Drosophila pseudoobscura |
| Characteristics |
tissue: whole body
gender: Male
age: 7-day-old
|
| Growth protocol |
Flies were reared on cornmeal/yeast medium and maintained at 20°C with a 12:12-h light/dark cycle.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Flies were instantly frozen in liquid nitrogen and stored in TRIZOL (Invitrogen) at -80°C. RNA was isolated using TRIZOL from at least 100 individuals. RNA quantity and quality were separately measured on a NanoDrop spectrophotometer (Thermo Scientific) and a Bioanalyzer 2100 (Agilent Technologies). High-quality samples (260/280>1.85; 260/230>1.7) further purified using the RNeasy kit (Qiagen).
|
| Label |
Cy3
|
| Label protocol |
Fluorescent cRNA was synthesized from 200 ng of total RNA using Agilent’s low-RNA input fluorescent linear amplification kit following manufacturer's protocols (Agilent Technologies). Labelled RNAs were cleaned with RNeasy columns (Qiagen), and cRNA yields were quantified on a NanoDrop spectrophotometer. Two separate labeling reactions per sample were pooled and hybridized to the arrays following Agilent’s protocols.

| Description |
Hybrids of Drosophila pseudoobscura (paternal) and Drosophila persimilis (maternal)
|
| Data processing |
Performed in HDBStat: data is normalized by flagging out bad spots, filtering unexpressed genes (average raw intensity across all the samples <50), negative and positive Agilent controls, and then normalized with Chip Mean and log2 transformation.
