Sample GSM662899 Query DataSets for GSM662899
Status Public on Jan 25, 2012
Title HeLa cells 2h released, biological rep2
Sample type RNA
 
Source name HeLa cell line
Organism Homo sapiens
Characteristics cell line: HeLa cells
growth condition: 2h released
Growth protocol RNA was purified from HeLa cells in double thymidine (0) and cells released into the cell cycle after washing out the thymidine. RNA was collected from cells at 2, 4, 6, 8 and 12 hours after washing out the thymidine.
Extracted molecule total RNA
Extraction protocol Trizol extraction of total RNA was performed according to the manufacturer's instructions. The RNA was then Dnase treated and purified using Qiagen Rneasy columns.
Label biotin
Label protocol RNA from each sample was converted into cDNA, then amplified and labeled with biotinylated nucleotides by in vitro transcription to produce biotinylated cRNA.
 
Hybridization protocol The cRNA was hybridized to a microarray chip.
Scan protocol The bound cRNA was stained with fluorescent streptavidin.
Description HeLa_2hR_2
Data processing R Bioconductor Affy package was used to analyze the microarray files. After loading the raw CEL files in R, RMA (Robust Multi-Array Averaging) was used to subtract background, normalize intensities and summarize gene expression levels
