CD Genomics has CGH microarray service for a number of species, including human, mouse, rat, and chicken, and custom CGH arrays for other species are also available. 

Microarray comparative genomic hybridization (CGH) allows a genome wide screen at a high resolution for the detection of previously cryptic copy number imbalance (deletions and duplications). CD Genomics’ validated procedures and optimized protocols, combined with high-resolution microarray scanning, and powerful analytic software yields the highest data quality and fastest turn-around time.More information, please visit the website: http://www.cd-genomics.com/CGH-Microarray-Service.html
