Frederick, MD. May 24, 2004 - SABiosciences Corp. announced today the launch and availability of its new RT² Real-Time™ Gene Expression Assay Kits for every gene in the human, mouse, and rat genomes. These quantitative gene expression assays are intended for genome-wide disease characterization, pathway elucidation, functional studies, and in the basic research of human disease. Additionally, they are ideal for independent verification of DNA microarray data.

Each RT² Real-Time™ Gene Expression Assay Kit includes gene-specific PCR primers designed with proprietary, experimentally verified design algorithms. The PCR primers are optimized for real-time PCR and SYBR Green detection. Also included is a specially optimized master mix for real-time PCR.

"This new product is a convenient, cost effective solution for large scale verification of microarray data. Our experimentally verified design algorithms ensure uniqueness of the desired amplicon in the target genome while minimizing undesirable characteristics like primer dimer formation. We are pleased to offer our customers such a flexible gene expression assay at a price every lab can afford", said Dr. Li Shen, President of SABiosciences Corp.

The RT² Real-Time™ Gene Expression Assay Kits can be ordered through the SABiosciences e-commerce site at http://www.sabiosciences.com/QRTsearch.php. This web page offers powerful search options that enable researchers to quickly identify and cross-correlate the assays relevant to their research by Gene Name, RefSeq Accession Number, and UniGene Number.

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