DNA from solid tissues was isolated using standard phenol – chloroform extraction method (Sambrook, J., Russell, D.W., 2001, Molecular Cloning: A Laboratory Manual, Volume 1st of 3, 6.4-6.12, Cold Spring Harbor Laboratory Press, ISBN 9780879695774) with modifications. DNA from blood samples was isolated by QIAamp DNA Blood Kit according to manufacturer’s protocol (QIAamp DNA Blood Midi Kit, QIAGEN, Hilden, Germany, #5118).
Label
Cy3
Label protocol
Sample labeling, hybridization, washing and two-color scanning was performed according to Nimblegen’s protocol with modification as previously described (Ronowicz et al. 2012, Anal Biochem. 426:91-3, PMID: 22504026).

Description
Comparative Genomic Hybridization of tissues from breast cancer patients
Data processing
Microarray data were extracted with DEVA software v1.2 CGH, including spatial correction (LOESS) and qspline fit normalization, in order to compensate for differences in signal between the two dyes (Workman et al., 2002, Genome Biol 3(9):research0048, PMID: 12225587).
Concurrent DNA copy number alterations and mutations in genes related to maintenance of genome stability in uninvolved glandular tissue from breast cancer patients
