Frederick, MD. June 25, 2004 - SABiosciences Corp. announced today the launch and availability of the first in its new line of pathway-specific Oligo GEArray® Focused DNA Microarrays. The initial Oligo GEArray offerings include gene content specific to human hematology and human cancer.

The Oligo GEArray Focused DNA Microarrays employ chemiluminescence detection and a new, one-tube labeling method to deliver optimum sensitivity and selectivity, while simplifying the overall protocol. The labeling, hybridization and detection protocols require only equipment found in a typical molecular biology laboratory.

"This new line of pathway-specific microarrays complements the already prolific biological pathways and applications represented by our popular GEArray cDNA Microarrays. The 60-mer oligo array system will allow us to more rapidly add new pathway-specific arrays to our present offerings. Additionally, the Oligo GEArray systems include carefully designed optimization control features and a robust, easy to use RNA amplification/labeling kit. We are pleased to offer our customers such a flexible, yet powerful, new gene expression research tool at a price every lab can afford", said Dr. Sean Yu, Vice President of Operations at SABiosciences Corp.

The Oligo GEArray® Microarray gene content can be easily customized, allowing complete tailoring of a microarray's gene content for as little as $100 per array. The SABiosciences web site guides prospective users through the process of ordering customized Oligo GEArrays.

SABiosciences Corp. develops and markets a wide range of innovative, pathway-focused life science research products. The company's four technology platforms are the foundation of its complementary toolset for systematic gene expression profiling (DNA microarrays), gene expression verification (PCR), gene suppression (siRNA) and gene function (ELISA) on a pathway-by-pathway basis.
