Sample GSM931340 Query DataSets for GSM931340
Status Public on May 16, 2012
Title Replication timing of 10-770 leukemic patient sample, replicate 2
Sample type genomic
 
Channel 1
Source name Early-replicating DNA of 10-770 leukemic patient sample
Organism Homo sapiens
Characteristics diagnosis: ALL (B), Pediatric
age (yrs): 12
gender: F
disease stage: New Diagnosis
karyotype: 46,XX[36]
Extracted molecule genomic DNA
Extraction protocol Replication timing data were obtained by hybridizing early and late replication intermediates to NimbleGen oligonucleotide arrays, as described in Hiratani et al [PLoS Biology (2008) 6: e245]. Briefly, replication intermediates are prepared from cells that are first pulse-labeled with BrdU and then sorted into early (1st half of S) and late (2nd half of S) stages of S-phase by flow cytometry, followed by anti-BrdU immunoprecipitation of the BrdU-substituted (nascent) replication intermediates that were synthesized either early or late during S-phase. Samples were labeled after unbiased amplification of recovered DNA by whole-genome amplification (WGA; Sigma, GenomePlex). Further details can be found in Hiratani et al [PLoS Biology (2008) 6: e245].
Label Cy3
Label protocol Standard NimbleGen protocol (www.nimblegen.com/products/lit/index.html). Briefly, randomly-amplified BrdU-immunoprecipitated DNA samples (1 ug each) were Cy3- or Cy5-labeled by Klenow reaction using end-labeled Cy3- or Cy5-random 9-mers.
 
Channel 2
Source name Late replicating DNA of 10-770 leukemic patient sample
Organism Homo sapiens
Characteristics diagnosis: ALL (B), Pediatric
age (yrs): 12
gender: F
disease stage: New Diagnosis
karyotype: 46,XX[36]

Label Cy5
Label protocol Standard NimbleGen protocol (www.nimblegen.com/products/lit/index.html). Briefly, randomly-amplified BrdU-immunoprecipitated DNA samples (1 ug each) were Cy3- or Cy5-labeled by Klenow reaction using end-labeled Cy3- or Cy5-random 9-mers.
 
 
Hybridization protocol Standard NimbleGen protocol (www.nimblegen.com/products/lit/index.html). Briefly, Cy3 and Cy5 labeled DNA samples (34 ug each) were co-hybridized to Nimblegen CGH arrays containing one oligonucleotide probe every 2.5 kb across the human genome.
Scan protocol NimbleGen MS200 microarray scanner (Roche NimbleGen, Inc.) and MS200 data collection software were used per NimbleGen's standard protocol (www.nimblegen.com/products/lit/index.html).
Description submitted as of 5/12/12
Data processing NimbleScan software was used to obtain .pair raw data per manufacturer's instructions. Raw early/late data (i.e. from .pair files) from two independent biological replicates in which early and late replicating DNA were differentially labeled were loess-normalized to remove signal intensity-dependent bias, then scaled to a reference data set to have the same median absolute deviation (limma package, R/Bioconductor).The early/late ratios were used to generate a smoothed profile (i.e. processed data) using local polynomial smoothing (loess, 300-kb span) for each chromosome using the loess function in the statistical language R. Processed data sets can be graphically displayed (and are also downloadable) on our web site (http://www.replicationdomain.org). Further details can be found in Hiratani et al [PLoS Biology (2008) 6: e245].
