Sample GSM142466 Query DataSets for GSM142466
Status Public on Oct 28, 2006
Title ABI_A2780_6h_rep2
Sample type RNA
 
Source name A2780 ovarian carcinoma cell line
Organism Homo sapiens
Characteristics A2780 ovarian carcinoma cell line
Biomaterial provider ECACC (Cat no.93112519)
Treatment protocol Human Ovarian cell line A2780 was untreated or exposed to 3 micromolar of a cell cycle inhibitor for 6hrs
Growth protocol A2780 was grown in RMPI 1640 + 10% FCS +2mM Glutamine and maintained at 37C in an atmosphere of 5% CO2 and 95% room air. Cells were plated at 2 x 106 cell/ml and after 24hrs were exposed to 3 micromolar of the inhibitor for 6hrs.
Extracted molecule total RNA
Extraction protocol Total RNA extraction was performed using Qiagen RNeasy Mini kit 74106 following manufacturers instructions.
Label Digoxigenin-UTP
Label protocol 2 micrograms of each RNA sample was labeled with Digoxigenin-UTP using the ABI Chemiluminescent RT-IVT Labeling Kit v 1.0 accordingly to manufacturer’s protocol.
 
Hybridization protocol 10micrograms of the labeled cRNA was hybridized to ABI Human Genome Survey Microarray v 1.0 accordingly to ABI’s protocol.
Scan protocol Following hybridization and washing steps, chemiluminescent detection and image acquisition was performed using Applied Biosystems 1700 Chemiluminescent Microarrays Analyzer, following manufacturer’s protocol.
Description Human Ovarian cell line A2780 was obtained from ECACC (Cat no.93112519) and cells were untreated or exposed to 3 micromolar of a cell cycle inhibitor for 6hrs. Three biological replicates were performed for each treatment. Only attached cells were harvested. RNA was purified using a Qiagen RNA purification kit. RNA was quantitated using a spectrophotometer and the quality of the RNA was assessed using a Bioanalyser.
Biological replicates were pooled to obtain a unique sample for each treatment, which was then divided to generate three aliquots for each condition (technical replicates).
Data processing Global median normalization was applied
