December 10, 2007 — Oxford Gene Technology (OGT) has launched the Oligome, a comprehensive database of more than 10 million oligonucleotide probes designed to the latest release of the human genome. The database makes it possible to provide custom-designed oligonucleotide arrays for array-based comparative genomic hybridisation (aCGH) on request, more quickly and at a lower cost than would normally be expected for a custom array, the company says.

OGT’s 60mer oligonucleotide microarrays are fabricated using inkjet technology with base-by-base synthesis that allows high precision feature placement, and denser coverage of regions of interest. OGT offers custom-designed CGH arrays for analysing chromosomal abnormalities within focused areas of the human genome at high resolution.

As part of the free design service, scientists can provide OGT their regions of interest. OGT then performs the Oligome-based bioinformatics required to design, fabricate and deliver the desired focused arrays.
