Sample GSM80486 Query DataSets for GSM80486
Status Public on Nov 01, 2005
Title ES/N2bFGF_2
Sample type RNA
 
Channel 1
Source name Mouse Embryonic Stem Cell
Organism Mus musculus
Characteristics control
Biomaterial provider Stem Cell Research Center
Treatment protocol no treatment
Growth protocol Undifferentiated R1 mouse ES cells (stage 1) were grown and maintained on gelatin-coated dishes with leukemia inhibitory factor (ESGRO, Invitrogen, NY) in ES cell medium, KODMEM supplemented with 15% FBS, nonessential amino acids, beta-mercaptoethanol, L-glutamine, and antibiotics
Extracted molecule total RNA
Extraction protocol Total RNA was prepared by using TriZol reagent (Invitrogen)
Label cy5
Label protocol With 5ug of total RNA, Microarray cDNA synthesis kit(Roche) was used for first and second strand cDNA synthesis. Then double strand cDNA was prufied with RNeasy mini kit(Qiagen). For in vitro transcription, T7 MegaScript(Ambion) was used with Cy5-UTP(5mM, Amersham pharmacia) for 16 hours at 37℃.
 
Channel 2
Source name N2bFGF
Organism Mus musculus
Characteristics treatment
Biomaterial provider Stem Cell Research Center
Treatment protocol EBs were dissociated and plated onto tissue culture dishes in the serum-free medium containing Insulin/Transferrin/Selenium/Fibronectin (ITSF). After 6 days, the cells were expanded and plated onto polyornithine (15 mg ml-1) and laminin-coated plates (Becton Dickinson Labware, Bedford, MA) with the N2 medium (Johe, 1996) supplemented with laminin, bFGF (R&D Systems, Minneapolis, MN), murine N-terminal fragment of SHH and murine FGF8 isoform b (R&D Systems) (stage 4) . Finally the cells were induced to differentiated into DA neurons by removal of bFGF.
Growth protocol Undifferentiated R1 mouse ES cells (stage 1) were grown and maintained on gelatin-coated dishes with leukemia inhibitory factor (ESGRO, Invitrogen, NY) in ES cell medium, KODMEM supplemented with 15% FBS, nonessential amino acids, beta-mercaptoethanol, L-glutamine, and antibiotics
Extracted molecule total RNA
Extraction protocol Total RNA was prepared by using TriZol reagent (Invitrogen)
Label cy3
Label protocol : With 5ug of total RNA, Microarray cDNA synthesis kit(Roche) was used for first and second strand cDNA synthesis. Then double strand cDNA was prufied with RNeasy mini kit(Qiagen). For in vitro transcription, T7 MegaScript(Ambion) was used with Cy3-UTP(5mM, Amersham pharmacia) for 16 hours at 37℃.
 
 
Hybridization protocol the labeled sample was resuspended with Hybridization buffer(50mM Na-Phosphate, ph8.1, 50% Formamide, 6X SSC, 5X Denhardtdts Solution, 0.5% SDS), then hybridized in humidified chamber at 42℃ for 24 hours.
Scan protocol Cy3 and Cy5 fluorescent intensities were determined using the GenePix scanner (Axon Instruments), and images were analyzed using the GenePix Pro.
Description ES/N2bFGF normalized log ratio
Data processing Variance stabilizing normalization was applied with the ‘vsn’ package in Bioconductor using the R statistical package. After performing intensity-dependent global LOWESS regression, spatial and intensity dependent effects were managed by pin-group LOWESS normalization.
