Sample GSM497554 Query DataSets for GSM497554
Status Public on Jan 12, 2011
Title T3_MEF-1, biological rep1
Sample type RNA
Source name hES-T3 cells grown on MEF feeder
Organism Homo sapiens
Characteristics growth conditions: grown on MEF feeder
gender: female
cell line: hES-T3
Treatment protocol No
Growth protocol Human embryonic stem cell line hES-T3, which is one of the five hES cell lines derived in our laboratory, exhibits normal female karyotype (46, XX), and it has been continuously cultured on mitomycin C (10 ug/ml) mitotically inactivated MEF feeder in hES medium under 5% CO2 at 37oC and underwent freezing/thawing processes. The hES culture medium consisted of DMEM/F12 (1:1, GIBCO) supplemented with 20% KSR (Invitrogen), 1% non-essential amino acids, 1 mM L-glutamine, 0.1 mM £]-mercaptoethanol, and 4 ng/ml human basic fibroblast growth factor (bFGF; Life Technologies). Routine passages of hES-T3 cells every 5-7 days were done with collagenase (type IV, 1 mg/ml, Invitrogen) treatment and mechanical scrape. The cryopreserved stock of hES-T3 cells (36 passages) were continuously maintained on MEF feeder for additional 14 passages, and these the hES-T3 cells were designated as T3/MEF.
Extracted molecule total RNA
Extraction protocol Trizol extraction of total RNA was performed according to the manufacturer's instructions. Total RNAs extracted using TRIZOL reagent were quantified spectrophotometrically. The cDNA synthesis was carried out by using SUPERSCRIPTTM one-step RT-PCR kit (Invitrogen). For the reverse transcription step, the whole 5 ul of the resuspended RNAs were incubated for 60 min at 42oC, then 15 min at 72oC in 50 ul of reaction mixture containing 25 ul of 2x Reaction Mix (Invitrogen) and 1 ul of RT/PLANTINUM Taq Mix (Invitrogen). 28.5 ul of the cDNAs present in the 50 ul RT reaction mixture purified by Microarray Target Purification Kit (Roche Applied Science, Indianapolis, ID, USA, were used as templates to amplify cDNA by Microarray Target Amplification Kit. The amplified cDNAs were purified by Microarray Target Purification Kit, and complementary RNAs (cRNAs) were synthesized from 200 ng cDNA with Microarray RNA Target Synthesis Kit (Roche Applied Science).
Label biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 5 micrograms purified cRNA (Expression Analysis Technical Manual, 2004, Affymetrix).
Hybridization protocol Following fragmentation, 10 micrograms of cRNA were hybridized for 16 hr at 45oC on Affymetrix Human Genome U133 plus 2.0 GeneChip. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
Scan protocol GeneChips from the hybridization experiments were read by the Affymetrix GeneChip scanner 3000.
Description The mRNA profiles from T3/CMHDF, T3/CMMEF, T3/HDF and T3/MEF were quantitatively determined.
Data processing The data were processed by GeneSpring software version 7.3 GC-RMA preprocessor to use on the CEL files
