Abstract
Comparative genomic hybridization to arrays, or array-CGH (aCGH) is a technique that allows genome-wide investigation of gains and losses of DNA sequences with a resolution at least 2 order of magnitude higher than classical cytogenetics. We first implemented aCGH at the Institute of Bioscience of University of São Paulo (IBUSP) in 2004 with the support of the CEPID - Human Genome Researc…
