Sample GSM618012 Query DataSets for GSM618012
Status Public on Jan 12, 2011
Title AGS treated rep 2
Sample type RNA
Source name AGS cells treated with 10 μg/ml H. pylori LPS for 8h rep 2
Organism Homo sapiens
Characteristics cell type: gastric epithelial cells
cell line: AGS
Treatment protocol The morning of treatment, the cell culture medium was replaced with either fresh medium (untreated) or medium containing 10 μg/ml H. pylori lipopolysaccharide
Growth protocol AGS cells were routinely maintained in nutrient mixture F-12 Ham (Sigma) supplemented with 10% foetal calf serum (Gibco), 2 mM L-glutamine (Sigma), 100 U/ml penicillin (Sigma) and 100 μg/ml streptomycin. The day before treatment, cells were seeded in 6-well plates at 1x106 cells/well.
Extracted molecule total RNA
Extraction protocol 8h post-stimulation, cells were harvested and RNA isolated using the Nucleospin RNAII kit (Machery Nagel) according to the manufacturer's instructions.
Label biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 5 μg total RNA (Expression Analysis Technical Manual, 2001, Affymetrix) using the Affymetrix IVT labeling kit.
Hybridization protocol Following fragmentation, cRNA was hybridized for 16 hr at 45C on Affymetrix U133 plus 2.0 genechips. GeneChips were washed and stained in the Automated fluidics 450 station.
Scan protocol Genechips were scanned using the GeneChip 3000 7G scanner
Description gene expression in H. pylori LPS-treated cells
Data processing Scanned images, obtained using Affymetrix Software (MAS5), were normalized using robust multichip average (RMA) analysis with RMAExpress version 0.4.1.
