Protocol Name P-MTAB-5492 P-NGEN-5 P-NGEN-9 P-NGEN-13 P-MTAB-5490 P-MTAB-5491 Protocol Type nucleic_acid_extraction labeling hybridization feature_extraction bioassay_data_transformation bioassay_data_transformation Protocol Description total RNA was extracted using Invitrogen's Trizol reagent.

Quality was assessed by gel electrophoresis and spectrophotometry (using a Nanodrop spectrophotometer).

cDNA was synthesised using an anchored poly(dT) primer (20mer) and INvitrogen's SuperscriptII reverse transcriptase. RNA was hydrolysed in basic conditions, and cDNA measured using a Nanodrop sprectrophotometer. About 2.5ug of cDNA were sent to Nimblegen for labelling (Cy3) and hybridisation using their own protocols.
(Parameters: Extracted product = total_RNA, Amplification = none) Title: NimbleGen Sample Labeling (Expression) v1.0. Description: Title: NimbleGen Hybridization & Washing (Expression) v1.0. Description: Title: NimbleGen One-Color Array Scanning (Expression) v1.0. Description: Raw data (one colour) were quantile normalised, and probesets summarised using the median polish algorithm. Normalised and summarised probeset data were processed with Limma (BioConductor) to fit a linear model, and obtain statistics for each probeset.
