Abstract

Array comparative genomic hybridization (aCGH) is a powerful tool to detect relative DNA copy number at a resolution limited only by the coverage of bacterial artificial chromosomes (BACs) used to print the genomic array. The amount of DNA needed to perform a reliable aCGH analysis has been a limiting factor, especially on minute tissue samples where limited DNA is available. Here we report a simple, highly sensitive and reliable aCGH method to analyze samples of no more than 1 ng genomic DNA. The speed and simplicity of the technique are ideal for studies on small clinical samples such as needle biopsies.
