Sample GSM159299 Query DataSets for GSM159299
Status Public on Jun 24, 2007
Title Col_dark_late_rep3
Sample type RNA
Source name Columbia 7 day old seedling, 120 minutes after transfer to darkness, night time
Organism Arabidopsis thaliana
Characteristics Strain: Columbia
Age: 7 Days
Tissue: Whole Seedling
Growth protocol About 100 seedlings were grown on a filter paper laid on 1xMSMO, 3% sucrose, 0.9% agar (Cat # A1296, Sigma) in 6 cm round Petri dishes. Seeds were stratified for four days at 4 ˚C and then incubated for four days at 20˚C under short day (8 hours light: 16 hours dark) conditions. The Petri dishes were tilted about 30˚ from vertical in a growth chamber equipped with red and blue LEDs (70.7 µE red light and 15.3 µE blue light). Starting from subjective dawn at day five, cycles of 160 min light and 320 min dark were given for three days. This sample was collected 1240 minutes after subjective dawn on the seventh day; 120 minutes after lights-off.
Extracted molecule total RNA
Extraction protocol Samples were transferred to 1.5 ml tube and immediately frozen by liquid nitrogen and stored at –80˚C. Samples were collected using infra-red (IR) goggles (Night Vision model NCB4, Night Owl Optics, NY) to avoid light exposure. 100 mg frozen tissue samples were ground by pestle and electric motor. Total RNA was extracted using RNeasy Plant Mini kit (Qiagen, CA).
Label biotin
Label protocol From 5 µg of total RNA, cRNA was made and labeled with biotin (Affymetrix, CA) according to protocol described by Schmid, M. et al. Nat. Genet. 37, 501-506 (2005).
Hybridization protocol Hybridization was performed in a Affymetrix 640 Hybridization Oven using standard Affymetrix protocols
Scan protocol Scans were performed on a Affymetrix GeneChip 3000 scanner.
Description Seedlings were entrained in short days for four days and then transferred to cycles of 160 min light and 320 min dark for three days. This sample was collected two hours after lights off, 1240 minutes after dawn on the seventh day.
Data processing Data was normalized using the RMA protocol.
