Sample GSM1065458 Query DataSets for GSM1065458
Status Public on Jan 17, 2013
Title Daphnia magna MTBE rep2
Sample type RNA
 
Source name Daphnia magna exposed for 24h
Organism Daphnia magna
Characteristics chemical: MTBE
age: 14 days
exposure time: 24h
dose: 145 mg/L
Treatment protocol Twenty daphnids (Two-week old) were exposed to 1 L of COMBO medium containing 1/10 LC50 concentration of each chemical with four replicates
Growth protocol D. Magna were obtained from Aquatic Research Organisms (Hampton, NH) and cultured at 20C in modified COMBO medium. Culturing medium was renewed three times a week, and Pseudokirchneriella subcapitata (formerly Selenastrum capricornutu) and YCT added for food.
Extracted molecule total RNA
Extraction protocol After 24 h exposure, total RNA was extracted with Trizol (Invitrogen, CA, USA) according to the standard method.
Label Cy3
Label protocol Agilent 1 colour Quick-Amp Labelling Protocol
 
Hybridization protocol Agilent 1 colour Quick-Amp Labelling Protocol
Scan protocol The scanning and feature extraction were performed using GenePix 4000B (Axon, USA) and GenePix Pro 6.0 software (Axon, USA).
Description Control-Media
Data processing Raw microarray data was read and normalized against their respective controls (listed in the description field) using loess within the statistical environment R using the marray and limma packages.
