Sample GSM328565 Query DataSets for GSM328565
Status Public on Jan 31, 2009
Title Populus x canescens root hypoxia_rep_07
Sample type RNA
Source name poplar root tissue flooded up to 168h
Organism Populus tremula x Populus alba
Characteristics Experiments were performed with 3-month-old hybrid poplar plants (Populus x canescens). At the beginning of the experiment, the shoots of the trees had a size of 20 to 25 cm. To induce root hypoxia 52 trees were transferred into large plastic containers. The containers were filled with tap water until the water level exceeded the soil surface by 2-3 cm. Shoots were exposed to ambient air.
Extracted molecule total RNA
Extraction protocol For total RNA extraction the Plant RNeasy kit (Qiagen) was used according to the manufacturer’s instructions with some minor modifications. Aliquots of 90 mg of frozen plant powder were added to 900 µl RLT buffer supplemented with 1% ß-mercaptoethanol, 1% PVPP and 2% (w/v) polyethylenglycol (PEG 10,000), and then incubated for 10 min at 58°C. The samples were further processed according to the manufacturer’s protocol. Total RNA was treated with DNase during (RNase free DNase kit, Qiagen) and after (DNA-free TM kit, Ambion) the extraction procedure.
The quality of the isolated total RNA was tested using an Agilent Bioanalyzer and spectrophotometric analysis (NanoDrop® ND-1000, NanoDrop Technologies) to determine the A260 to A280 ratio.
Label Biotin
Label protocol Labelling of cRNA from 3.5 µg of root total RNA was performed exactly as described in the Affymetrix GeneChip Expression Analysis Technical Manual.
Hybridization protocol standard Affymetrix protocol (see GeneChip Expression Analysis Technical Manual)
Scan protocol standard Affymetrix protocol (see GeneChip Expression Analysis Technical Manual)
