aCGH Analysis

Human Genome CGH Microarrays

The Agilent Human Genome CGH Microarray is a dual color array containing 60-mer oligonucleotide probes synthesized in situ using Agilent’s inkjet SurePrint technology. Its comprehensive probe coverage allows genome-wide DNA copy number variation profiling while focusing on known genes, promoters, miRNAs, pseudoautosomal and telomeric regions.

  • Multiple microarray formats and bundled options available
  • Distinct microarray catalog kits containing regions recommended by ISCA
  • Probes annotated against NCBI Build 37 (UCSC hg19, February 2009)

Comparative genomic hybridization (CGH) is used for genomic copy-number variations (CNV) research. CGH microarray technology platform by Agilent, Inc. allows for the discovery of novel oncogene, anti-oncogene, drug target, and biomarkers through identifying chromosomal abnormalities in cancer and genetic disorders.

Types of Agilent Arrays

Many variations of array exist based on the resolution. Not only human, but also arrays for mouse, rat, and chicken are available, and others besides them are also customizable. If you provide us with DNA of high quality, you are guaranteed to receive the finest result possible, and please note that different DNA amount may be required based on the type of chips
