Sample GSM107581 Query DataSets for GSM107581
Status Public on Dec 22, 2006
Title 6microg/L_Cu_Exposed_rep1B
Sample type RNA
 
Channel 1
Source name whole organism, exposed 24-h to 6 microg/L Cu
Organism Daphnia magna
Characteristics Daphnia magna: Aquatic Research Organisms
Age: 15-18 days
Biomaterial provider Vulpe Lab
Treatment protocol 24-h exposure to 6 microg/L Copper Sulfate
Growth protocol Genetically homogeneous Daphnia magna, purchased from Aquatic Research Organisms (Hampton, NH), were cultured in COMBO modified for water hardness (Kilham et al. 1998) and kept at 23.50 C in a Percival environmental chamber with a 16-hour light/ 8 hour dark cycle. The D. magna were maintained on a diet of YCT and Selenastrum capricornatum (Aquatic Research Organisms, Hampton, NH). Stock culture medium was renewed, cultures were fed, and neonates were separated from adults three times weekly.
Extracted molecule total RNA
Extraction protocol Trizol method (invitrogen)
Label cy3
Label protocol see the protocols at the website of Dr. Patrick O. Brown's laboratory at Stanford University
 
Channel 2
Source name whole organism, unexposed
Organism Daphnia magna
Characteristics Daphnia magna: Aquatic Research Organisms
Age: 15-18 days
Biomaterial provider Vulpe Lab
Treatment protocol untreated 24 hours
Growth protocol Genetically homogeneous Daphnia magna, purchased from Aquatic Research Organisms (Hampton, NH), were cultured in COMBO modified for water hardness (Kilham et al. 1998) and kept at 23.50 C in a Percival environmental chamber with a 16-hour light/ 8 hour dark cycle. The D. magna were maintained on a diet of YCT and Selenastrum capricornatum (Aquatic Research Organisms, Hampton, NH). Stock culture medium was renewed, cultures were fed, and neonates were separated from adults three times weekly.
Extracted molecule total RNA
Extraction protocol Trizol method (Invitrogen)
Label cy5
Label protocol see the protocols at the website of Dr. Patrick O. Brown's laboratory at Stanford University
