Sample GSM458844 Query DataSets for GSM458844
Status Public on Nov 23, 2009
Title MLL-AF4 infant ALL, 601
Sample type genomic
 
Channel 1
Source name peripheral blood, t(4;11)
Organism Homo sapiens
Characteristics tissue: peripheral blood
gender: male
genotype: t(4;11)
Treatment protocol Only applicable for the cell lines: treated with 100nM of zebularine for 10 days.
Growth protocol All cell lines were maintained as suspension cultures in RPMI 1640 with L-Alanyl-L-Glutamine (Invitrogen) supplemented with 10% FCS (Integro), 100 IU/ml penicillin, 100 μg/ml streptomycin, and 0.125 μg/ml fungizone (Invitrogen) at 37°C in humidified air containing 5% CO2.
Extracted molecule genomic DNA
Extraction protocol Total DNA extracted using Trizol following manufacturer's instructions.
Label Cy5
Label protocol Using the BioPrime Array-CGH Genomic Labeling kit (Invitrogen, Carlsbad, USA), amino-allyl dUTPs were incorporated into 500ng of the methylated amplicons (generated by DMH) , allowing the amplicons to be labeled with the fluorescent dyes Cy5 (patient samples) and Cy3 (common reference samples).
 
Channel 2
Source name peripheral blood, healthy
Organism Homo sapiens
Characteristics tissue: peripheral blood
sample description: mix from 5 healthy males and 5 healthy females
sample type: reference
Treatment protocol Only applicable for the cell lines: treated with 100nM of zebularine for 10 days.
Growth protocol All cell lines were maintained as suspension cultures in RPMI 1640 with L-Alanyl-L-Glutamine (Invitrogen) supplemented with 10% FCS (Integro), 100 IU/ml penicillin, 100 μg/ml streptomycin, and 0.125 μg/ml fungizone (Invitrogen) at 37°C in humidified air containing 5% CO2.
Extracted molecule genomic DNA
Extraction protocol Total DNA extracted using Trizol following manufacturer's instructions.
Label Cy3
Label protocol Using the BioPrime Array-CGH Genomic Labeling kit (Invitrogen, Carlsbad, USA), amino-allyl dUTPs were incorporated into 500ng of the methylated amplicons (generated by DMH) , allowing the amplicons to be labeled with the fluorescent dyes Cy5 (patient samples) and Cy3 (common reference samples).
 
 
Hybridization protocol Oligoarray control targets and hybridization buffer (the Oligo aCGH/ChIP-on-Chip Hybridization Kit) were added, and samples were applied to microarrays enclosed in Agilent SureHyb-enabled hybridization chambers. After hybridization, slides were washed sequentially according to the Agilent protocol.
Scan protocol Scanned on an Agilent G2565AA scanner.
Description pro-B

Please refer to Differential Methylation Hybridization (DMH) protocol by Dr. Tim H. Huang and coworkers. (PMID 18987809: Yan PS, Potter D, Deatherage DE, Huang TH, Lin S., Differential methylation hybridization: profiling DNA methylation with a high-density CpG island microarray.Methods Mol Biol. 2009;507:89-106.)
Data processing Images were quantified using Agilent Feature Extraction Software (version A.8.5.1.1).
Agilent Feature Extraction Software (v 8.5.1.1) was used for data extraction. The R and Bioconductor statistical environment (version 2.7) were used for quality control and LOESS normalization (limma package). No background correction was performed.
