Frederick, MD. August 15, 2005 - SABiosciences (www.sabiosciences.com) announced today the release of a very simple and fast microarray technology platform for profiling the expression of a focused set of genes. These microarrays, marketed under the trade name GEArray Express, feature an easy-to-handle and time-saving protocol allowing one trained technician to comfortably process up to 32 arrays in a single day.

One major bottleneck in using microarrays to screen large numbers of samples is low sample throughput. Traditionally, microarrays are processed in individual hybridization chambers, with a maximum throughput of about ten arrays in two days. The GEArray Express Platform enables the simultaneous processing of 32 microarrays in a single day. It simplifies the microarray hybridization and washing protocol with a multi-chamber hybridization plate that holds eight microarrays and a specialized but inexpensive thermal shaker that holds four plates. This innovative setup not only speeds up microarray experiments, but also improves their sample-to-sample and day-to-day consistency. GEArray Express makes the use of microarray technology for screening large numbers of samples more technically feasible and economically affordable. Nearly 100 samples can be processed in 3 days at a cost of less than $100 per sample.

"Our R & D department has been focusing on making microarrays more reliable and easy to use. We want microarrays to be used in every laboratory as a routine tool, like PCR is used today", said Dr. Sean Yu, Vice-President at SABiosciences. "The GEArray Express platform was designed to be inexpensive, easy-to-handle, fast, and more consistent. It is especially suitable for projects with a large number of samples. However, we also want every researcher to take advantage of the improved consistency and simplified handling," continued Yu.

Cataloged GEArray Express microarrays contain the same pathway- and disease-focused design for which SABiosciences has become well-known. Currently available topics in the GEArray Express format include apoptosis, cancer, cardiovascular disease, immunology, signal transduction, and toxicology. Researchers can also custom-order (or personalize) GEArray Express microarrays and tailor the content of a microarray with any set of human, mouse or rat genes important to their research.
