Sample GSM740104 Query DataSets for GSM740104
Status Public on Jun 11, 2011
Title Amoeboid microglia from 5-day rat brain biological rep2
Sample type RNA
 
Source name Amoeboid microglia from 5-day rat brain
Organism Rattus norvegicus
Characteristics age: Postnatal day 5
tissue origin: brain
tissue type: corpus callosum
cell type: Microglia
cell morphology: Amoeboid (AMC)
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from 600 microglia cells isolated by Laser-capture microdissection using RNeasy micro kit according to the manufacturer's instructions.
Label biotin
Label protocol Total RNA (15ng) was reverse transcripted into the first-strand cDNA using a T7-Oligo (dT) Primer (Two-Cycle Target Labeling and Control Reagent package, Affymetrix, CA, USA). After second-strand cDNA synthesis, the double-stranded cDNA was purified and served as a template in the first cycle of in vitro transcription (IVT) reaction. The unlabeled cRNA was then reverse transcripted into the first-strand cDNA of the second cycle using random primers. Subsequently, the T7-Oligo(dT) Promoter Primer was used in the second-strand cDNA synthesis to generate double-stranded cDNA template containing T7 promoter sequences. Then the double-stranded cDNA was amplified and labeled using a biotinylated nucleotide analog/ribonucleotide mix in the second IVT reaction.
 
Hybridization protocol The labeled cRNA was then cleaned up, fragmented, and hybridized to Rat Genome 230 2.0 Array (Cat. No. 900506, Affymetrix, CA, USA).
Scan protocol The arrays were stained according to the manufacturer's protocols and then scanned with the Genechip scanner (Affymetrix, CA, USA).
Description Gene expression data from amoedboid microglia isolated from corpus callosum of 5-day rat brain
Data processing CEL files were exported to Affymetrix Expression Console Version 1.1 and RMA normalization was carried out. [The data were also analyzed with Microarray Suite version 5.0 (MAS 5.0) using GeneChip Operating Software (GCOS, Affymetrix, CA, USA). For absolute analysis, each chip was normalized to a target intensity of 500, and probe sets were assigned a signal intensity and detection call of Present, Marginal or Absent (See MAS5_GCOS_analyzed.txt on GSE29885)]
