Sample GSM140968 Query DataSets for GSM140968
Status Public on Apr 24, 2007
Title DC_Unstimulated_Rep2
Sample type RNA
 
Source name primary dendritic cells (DCs)
Organism Homo sapiens
Characteristics Buffy coats were obtained from the National Blood Centre. Circulating myeloid DCs were isolated from buffy coats by adherence and culture in IL-4 and granulocyte-macrophage colony-stimulating factor (GM-CSF). DC preparations analyzed were more than 98% pure.
Biomaterial provider UK National Blood Centre
Treatment protocol Circulating myeloid DCs were isolated from buffy coats by adherence and culture in IL-4 and granulocyte-macrophage colony-stimulating factor (GM-CSF).
Growth protocol DCs were grown in R10 with IL4 and GM-CSF. Media changes occured every 48-72hr
Extracted molecule total RNA
Extraction protocol RNA was extracted using RNeasy kits (Qiagen).
Label Biotin
Label protocol 2 microgram RNA together with appropriate dilutions of GeneChip eukaryotic poly-A RNA spike controls (Affymetrix # 900433) was converted to double-stranded cDNA with superscript II (Invitrogen #11917-010) using T7-(dT)24 primer (Affymetrix 900375). This was used in an in vitro transcription to generate biotin-labelled cRNA probes.
 
Hybridization protocol Fragmented labelled cRNA (15µg) was used in 300µl hybridization cocktail containing spiked controls (Affymetrix #900299). A 200µl of this hybridization cocktail was used on the chip and incubated at 45°C for 16 h in the hybridization oven, rotating at 60 rpm. Following hybridization, the arrays were processed using a Genechip Fluidics Station 400 according to recommended protocols (EukGE-WS2v5, Affymetrix) of double-staining and post-hybridisations washes.
Scan protocol Fluorescent images were captured using gene Array Scanner 3000 and GCOS1.2 software (Affymetrix).
Description Circulating monocyte derived DCs were isolated from buffy coats by adherence and culture in IL-4 and granulocyte-macrophage colony-stimulating factor (GM-CSF). DC preparations analyzed were more than 98% pure. At day four 10 million immature DCs were either left unstimulated or stimulated using plate bound anti-DC-SIGN antibody for 2 hr. Three replicates of non-stimulated or stimulated cells were taken and used to extract total RNA.
Data processing We have used the genechip robust multi-array average expression measurements (GC-RMA) (37-39) as implemented in BioConductor R statistics (www.bioconductor.org). Cell Intensity files (CEL) were used to obtain expression values for all the 54,675 probe sets (transcripts) on each of these arrays.
