Sample GSM476856 Query DataSets for GSM476856
Status Public on Jul 31, 2010
Title NBC6 (Methylation)
Sample type genomic
 
Channel 1
Source name magnetic bead purified IgD+ naïve B cell from healthy donors undergoing routine tonsillectomy
Organism Homo sapiens
Characteristics restriction enzyme: MspI representation of genomic DNA
sample type: magnetic bead purified IgD+ naïve B cell from healthy donors undergoing routine tonsillectomy
cell line: n/a
Biomaterial provider the Children’s Hospital at Montefiore
Extracted molecule genomic DNA
Extraction protocol Genomic DNA from blood was isolated using Puregene Cell and Tissue Kit according to the manufacturer instructions (Qiagene). Genomic DNA from RNeasy (Qiagen) flow-through was first precipitated with Ethanol, then purified following proteinase K digestion and standard phenol/choloroform extraction protocol. Representation of the genome generated by digestion with either MspI or HpaII and amplification by ligation-mediated PCR according to the HELP protocol (See B. Khulan, et al. Genome Res. 2006 Aug;16(8):1046-55).
Label Cy3
Label protocol Random 9-mers pre-labeled with either Cy5 or Cy3

Hybridization protocol See Roche NimbleGen website and Selzer RR, Richmond TA, Pofahl NJ,Green RD, Eis PS, et al. (2005) Analysis of chromosome breakpoints in neuroblastoma at sub-kilobase resolution using fine-tiling oligonucleotide array CGH. Genes Chromosomes Cancer 44: 305-319. for details.
Scan protocol Scanning was performed using a GenePix 4000B scanner (Axon Instruments) as previously described in Selzer RR, Richmond TA, Pofahl NJ, Green RD, Eis PS, et al. (2005) Analysis of chromosome breakpoints in neuroblastoma at sub-kilobase resolution using fine-tiling oligonucleotide array CGH. Genes Chromosomes Cancer 44: 305-319.
Description Genomic DNA from blood was isolated using Puregene Cell and Tissue Kit
Data processing Signal intensities at each HpaII amplifiable fragment were calculated as a robust (25% trimmed) mean of their component probe-level signal intensities. Any fragments found within the level of background MspI signal intensity, measured as 2.5 mean-absolute-differences (MAD) above the median of random probe signals, were categorized as “failed.” These “failed” loci therefore represent the population of fragments that did not amplify by PCR, whatever the biological (e.g. genomic deletions and other sequence errors) or experimental cause. On the other hand, “Methylated” loci were so designated when the level of HpaII signal intensity was similarly indistinguishable from background.PCR-amplifying fragments (those not flagged as either “methylated” or “failed”) were normalized using an intra-array quantile approach wherein HpaII/MspI ratios are aligned across density-dependent sliding windows of fragment size-sorted data (described in detail in Thompson et al, Bioinformatics 2008;24:1161-1167.)
