PG - 1722-36 LID - 10.1038/nprot.2009.183 [doi] AB - Array painting is a technique that uses microarray technology to rapidly map chromosome translocation breakpoints. Previous methods to map translocation breakpoints have used fluorescence in situ hybridization (FISH) and have consequently been labor-intensive, time-consuming and restricted to the low breakpoint resolution imposed by the use of metaphase chromosomes. Array painting combines the isolation of derivative chromosomes (chromosomes with translocations) and high-resolution microarray analysis to refine the genomic location of translocation breakpoints in a single experiment. In this protocol, we describe array painting by isolation of derivative chromosomes using a MoFlo flow sorter, amplification of these derivatives using whole-genome amplification and hybridization onto commercially available oligonucleotide microarrays. Although the sorting of derivative chromosomes is a specialized procedure requiring sophisticated equipment, the amplification, labeling and hybridization of DNA is straightforward, robust and can be completed within 1 week. The protocol described produces good quality data; however, array painting is equally achievable using any combination of the available alternative methodologies for chromosome isolation, amplification and hybridization.
