Sample GSM792479 Query DataSets for GSM792479
Status Public on Nov 19, 2012
Title Non Infected BalbC macrophages at T6, rep1
Sample type RNA
 
Source name Non infected (NI) Mouse Macrophges at 6 hrs
Organism Mus musculus
Characteristics strain: wild type BALB/c (Elevage Janvier)
tissue: Bone Marrow-derived macrophage (BMdM)
Treatment protocol BMdM were incubated at a parasite to cell ratio of 10:1 with Ficoll purified metacyclic promastigotes of Leishmania major at 37°C in 5% CO2 during respectively T1,T3,T6,T12 and T24 hours post infection.
Growth protocol Bone Marrow cells were grown for 7 days, with re-feeding on day 3, to induce macrophage differentiation. Generated macrophages were assessed by flow cytometry for expression of F4/80 (around 90% were positive).
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 100 ng of total RNA (Expression Analysis Technical Manual, Affymetrix).
 
Hybridization protocol 100 ng of Total RNA were proceeded according to the GeneChip whole transcript sense target labeling assay manual using the GeneChip WT cDNA Synthesis, amplification Kit and WT terminal labeling Kit. The fragmented and labeled ssDNA was hybridized to a GeneChip Mouse Gene 1.0 ST array, washed with the Fluidics station 450.
Scan protocol GeneChips were scanned using the Affymetrix Scanner 30007G.
Description NI_T6_B36
Gene expression data from non infected (NI) BalbC macrophages at T6
Data processing The data preprocessing step included intrachip and interchip normalisation and summarisation. The intrachip normalisation step corrects for the GC content of the probes, the interchip normalisation step reduces non-biological differences between chips and the summarisation step combines the probe intensities into single gene expression values. For the intrachip normalisation the 'Model-based Analysis of Tiling-arrays' (MAT) was implemented as described by Kapur, Ket al., 2007. Genome Biol 8:R82, since this method provides the most advanced GC correction for whole-transcript prepared samples. As a last step in the preprocessing of the data we applied a summarisation of probe intensities to a probe set expression [Processed/nomalized data and additional data processing details were provided as Series supplementary files].
