Sample GSM372015 Query DataSets for GSM372015
Status Public on Feb 19, 2009
Title T4 vs T6 third biological replica
Sample type RNA
 
Channel 1
Source name T63
Organism Mytilus galloprovincialis
Characteristics treatment: Okadaic acid
age: 5 weeks post treatment
biological replica: 3
tissue: digestive gland
Treatment protocol 6.5 µg of Okadaic acid (Sigma Chemical Co.) diluted in 1 mL ethanol every two days for a time span of 5 weeks
Growth protocol Mussels were maintained in tanks provided with oxygen-pump and water-lively pump in sea water. To prevent additional environmental stress, the seasonal photoperiod (L 10-D 14) and water temperature (17°C) were maintained. Sea water was changed weekly and water salinity (37 PSU) was controlled daily.
Extracted molecule total RNA
Extraction protocol Total RNA extracted using RNAtidy G following manufacturer's instructions plus an additional LiCl precipitation
Label Cy3
Label protocol Total RNA was retro-transcribed using Superscript II Reverse Transcriptase (Invitrogen) with aminoallyl-dUTP and then labelled with Cy5 or Cy3 fluorescent dyes (GE Healthcare)

Hybridization protocol labelled cDNAs were hybridised in SSC 5X, Sarcosile 0.1%, Denhardt sol 1X overnight at 48°C, the slides were washed with decreasing stringency buffer untill SSC 0.05X.
Scan protocol Bio-Rad Chip Reader, laser powers 100% and detector sensitivity varied to balance the two channel intensities
spots were inspected and quantified with Bio-Rad Cheap Reader's software.
Description Digestive gland responses to okadaic acid treatment, loop design
Data processing Raw data was first background subtracted then normalized with the LOESS algorithm. Finally a quantile normalization was apply. R software was used implemented with LIMMA package
