Sample GSM142450 Query DataSets for GSM142450
Status Public on Oct 28, 2006
Title A2780_TRT_6h_rep1
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 biotin
Label protocol 5 micrograms of each RNA samples was used for the amplification/labelling reaction. 1st and 2nd strand cDNA synthesis was performed with the Invitrogen kit (11917-020) and the IVT reaction was done with Megascript T7 from Ambion (1334). All steps were done according to manufacturers instructions and cRNA was quantitated on a spectrophotometer. 15 micrograms of cRNA was fragmented and checked by denaturing gel electrophoresis. Bacterial transcripts at the cRNA level were spiked into each sample prior to hybridisation.
 
Hybridization protocol 10 micrograms of fragmented cRNA was hybridised to a Human Genome U133 Plus 2.0 Array (900466). Hybridisations, washing and staining were performed according to Affymetrix protocols
Scan protocol Hybridised arrays were scanned with the Genechip Scanner 3000
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 Probe set intensities were calculated using the RMA algorithm and normalized by the quantiles method
