From: Gene-resolution analysis of DNA copy number variation using oligonucleotide expression microarrays
A local copy number difference between two closely related cell lines is observed using both aCGH platforms. SK-N-SH/G (red) and SK-N-SH/L (blue), two cell lines derived from the same patient, show copy number differences at 140 to 228 Mb of chromosome 1, where SK-N-SH/L shows gain while SK-N-SH/G shows normal DNA content. Segmentation analysis of BAC aCGH (A) and graCNV (B) highlight the same region as amplified. log2 copy numbers inferred from CBS are shown as red (SK-N-SH/G) and blue (SK-N-SH/L) lines.
