aCGH (microarray-based comparative genomic hybridization) is a microarray-based technique used to identify and characterize DNA copy number variations across the genome. Arraystar provides aCGH service from sample to data. The ultra-high density 2.1 million feature arrays offer unprecedented data resolution for CGH analysis. They enable genome-wide detection of copy number variants (CNVs) down to ~5kb in size and analysis of targeted regions at the exon-level resolution.

 

We provide services for all the aCGH arrays available from Roche-NimbleGen. The aCGH arrays that are most often selected by our customers include:

Species	Format	Probe Median Spacing	Genome Build	Description
Human	1 * 2.1M	1,169bp	hg18	Whole genome
Human	3 * 720K	4,750bp	hg18	Whole genome
Human	1 * 385K	20-575bp	hg18	Chr. specific
Mouse	3 * 720K	3,537bp	Mm9	Whole genome
