Sample GSM782722 Query DataSets for GSM782722
Status Public on Mar 15, 2012
Title A375 siRNA-MAPK1 48h
Sample type RNA
 
Source name A375 cells that were transfected by siRNA targeting the corresponding gene
Organism Homo sapiens
Characteristics cell line: A375
knockdown: siRNA-MAPK1
Treatment protocol A375 cells were seeded in 6-well plates. 20h after seeding when the cells reached 30% confluence, they were transfected with 100nm of siRNA with 30μl Oligofectamine accroding to the manufacture's instruction. After 48h, the cells were harvested and RNAs were used for the microarray analysis.
Growth protocol A375 cells were grown in DMEM medium containing 10% FBS at 37 ˚C in a fully humidified atmosphere containing 5% CO2
Extracted molecule total RNA
Extraction protocol Trizol extraction of total RNA was performed according to the manufacturer's instructions.
Label biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 4 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
 
Hybridization protocol Following fragmentation, 15 ug of labelled cRNA was hybridized for 16 hr at 45°C @ 60 RPM on Affymetrix GeneChip Human Genome U133 Plus 2.0 Arrays. GeneChips were washed and stained in the Affymetrix Fluidics Station 450
Scan protocol GeneChips were scanned using the Affymetrix GeneChip Scanner 7G
Description Gene expression profile of A375 cells 48 h after the corresponding gene was knockdown by siRNA was analyzed using Affymetrix Human Genome U133 plus 2.0 microarrays
Data processing The data were analyzed with R using Affymetrix default analysis settings and RMA as normalization method.
