New CGH products.

Two new products for comparative genomic hybridization (CGH) debuted at AACR's annual meeting. CGH is used to detect genomic mutations responsible for cancer at the chromosomal and subchromosomal levels.

Earlier this year, Agilent introduced the genome-wide Human Genome CGH Microarmy and CGH Analytics software. The chip features 40,000 60-mer oligonucleotide probes with an average spatial resolution of 75 kilobase and requires 25 nanograms of DNA.

At AACR, NimbleGen debuted its CGH microarrays, the Human Whole-Genome Array CGH and Custom Fine-Tiling Array CGI-L Each chip features 385,000 long-oligonucleotide probes. The Whole Genome Army's median probe spacing is 6,000 base pairs.

On the automation front, Genetix introduced an integrated system targeting array-based CGH from extraction of DNA through scanning and analysis. It consists of labeling kits, automated done pickers, arraying platforms and a high resolution scanner.
