Sample GSM1121621 Query DataSets for GSM1121621
Status Public on Apr 12, 2013
Title Control-1
Sample type RNA
 
Source name Control
Organism Mus musculus
Characteristics cell type: Ebf1-/- pre-pro-B cell line
transduction: control MigR1 virus
Treatment protocol High titer virus was generated using a CaPO4 transfection protocol. Cultures were supplemented with fresh medium at 12h post-infection and harvested for downstream applications at indicated time points post-infection.
Growth protocol Ebf1-/- progenitors were propagated and maintained on OP9 stromal cells in Opti-MEM, 10% FCS, primatone, L-glutamine, and Pen/Strep supplemented with 10 ng/ml each of IL-7, flt3-ligand (FL) and stem cell factor (SCF).
Extracted molecule total RNA
Extraction protocol Target preparation and hybridization protocols were conducted as described in the Ovation Pico WTA System V2 User Guide (NuGEN) and the Affymetrix GeneChip Expression Analysis Technical Manual. Briefly, [50ng] of total RNA was converted to first-strand cDNA using reverse transcriptase primed by poly(T) and random oligomers that incorporated an RNA priming region. Second-strand cDNA synthesis was followed by ribo-SPIA linear amplification of each transcript using an isothermal reaction with RNase, RNA primer and DNA polymerase, and the resulting cDNA was fragmented, assessed by Bioanalyzer, and biotinylated by terminal transferase end labeling. cDNA yields ranged from 5-9ug
Label biotin
Label protocol Protocols were conducted as described in the Affymetrix GeneChip Expression Analysis Technical Manual. Quality and quantity of extracted RNA was tested on a bioanalyser by UPENN Microarray Core Facility. the resulting cDNA was fragmented, assessed by Bioanalyzer, and biotinylated by terminal transferase end labeling. cDNA yields ranged from 5-9ug
 
Hybridization protocol Biotinylated targets were heated at 99 °C for 5 min and hybridized for 16 h at 45 °C. The microarrays were then washed at low (6× SSPE) and high (100 mM MES, 0.1 M NaCl) stringency and stained with streptavidin-phycoerythrin. Fluorescence was amplified by adding biotinylated anti-streptavidin and an additional aliquot of streptavidin-phycoerythrin stain.
Scan protocol GeneChips were scanned using the GeneArray Scanner 3000 7G.
Data processing The data were analysed using Partek Genomics Suite, version 6.5 (Partek). Robust multichip average (RMA) with default settings was used to normalize data.
