Sample GSM435251 Query DataSets for GSM435251
Status Public on Feb 02, 2013
Title H27M_rep3_Array3
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.
Hybridization protocol Agilent’s protocols
Scan protocol 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.
