High-resolution comparative genome hybridization survey of healthy individuals (chromosome 22)

ABSTRACT: HighRes-CGH arrays that utilize ≈385,000 distinct oligonucleotide probes to cover chromosome 22 at 85 bp resolution (tiling path step size) were designed and synthesized as previously described (Urban et al., Proc Natl Acad Sci U S A. 2006;103(12):4534-9; see also GSE4240 record). Here, two healthy individuals were studied using the same experimental protocols as in Urban et al. See above, same as in Urban et al., Proc Natl Acad Sci U S A. 2006;103(12):4534-9; see also GSE4240 record. The overall goal of the study was the detection of the precise boundaries of deletions and amplifications. Maskless array synthesis was used to construct custom isothermal arrays containing up to 385,000 oligonucleotides, tiling the non-repetitive regions of chromosome 22. Genomic DNA isolated from patients (Cy3) was co-hybridized with a reference DNA pool (Promega; Cy5).
