Frederick, MD. June 15, 2005 - SABiosciences (www.sabiosciences.com) announced today the launch of its new GEArray personalized microarray program. This program allows researchers to individually tailor the gene content on low-density microarrays quickly and cost-effectively with any set of human, mouse or rat genes important to their research. By combining this flexibility with the simplicity and affordability of their GEArray technology, SABiosciences hopes to make customized microarrays a routine, tool for every gene expression project.

SABiosciences is already a leading provider of Pathway-Focused DNA Microarrays. Derived from the current literature and public databases in what they call a "knowledge-based design", the content of their cataloged microarrays covers over 50 different pathways and diseases. Currently available topics include cancer, immunology, neuroscience, cardiovascular disease, toxicology, signal transduction, apoptosis, stem cells and developmental biology. "However," noted David Martz, Director of Marketing and Sales at SABiosciences, "researchers are really the ones who know which genes are most important for their specific research project. Their gene lists may come from their own literature reviews, or may be discovered through their own microarray-based surveys of the whole genome. This custom microarray service provides them with the affordable flexibility they need to make the ideal focused microarray for their initial experiments or larger screening and validation projects."

The customized microarrays utilize the same technology platform as SABiosciences' cataloged Oligo GEArrays. By combining a nylon matrix with a high DNA binding capacity and advanced technologies for array labeling and chemiluminescent detection, SABiosciences reports that this GEArray system delivers excellent sensitivity and robust performance using as little as 100 ng of total RNA, or even less with a modified protocol. "The method is very easy to perform and doesn't need any special or dedicated equipment," continued Martz. "The low price also allows it to be used routinely in any biological laboratory setting. With their flexibility, ease-of-use and low cost, these custom arrays should be well-suited for a very wide range of laboratories interested in microarray experiments."
