SeraCare Launches Genetic Testing Controls Business Line

SeraCare Life Sciences, Inc. (NASDAQ: SRLS) launched the Company's anticipated genetic controls business with the introduction of two new products at the Association for Molecular Pathology 2008 Annual Meeting. Initial products launched include ACCURUN(R) 601 controls for diagnostic testing of warfarin sensitivity and ACCURUN(R) 610 controls for thrombophilia testing, which were developed internally by SeraCare. Additionally, the Company announced that it has entered into an exclusive licensing and technology transfer agreement with Sacred Heart Medical Center & Children's Hospital, Spokane, WA, which allows SeraCare to manufacture and distribute additional controls for genetic testing, including screening for cystic fibrosis and for diseases common among people of Ashkenazi Jewish ancestry, under patents and proprietary know-how owned by Sacred Heart.

"SeraCare intends to build a thriving genetic controls business line offering differentiated genetic controls that make our customers' jobs easier and more productive. We will apply the same in-house expertise, quality systems and state-of-the-art manufacturing facilities that are driving double-digit growth in our molecular controls business to our new genetic controls franchise," said Susan Vogt, President and CEO. "In the coming months, we will continue to make key additions to the genetic controls product portfolio as this business line plays an important role in the Company's near-term growth strategy and future profitability."

About ACCURUN(R) 601:

Warfarin is the most widely prescribed oral anticoagulant for thrombosis, stroke and other clotting disorders. In August of 2007 the Food and Drug Administration approved a re-labeling of warfarin that indicates new patients on warfarin should undergo genetic testing prior to long term use of the drug to alleviate dosing regimen problems and reduce adverse events, including significant risk of bleeding. Two genes seem to have an effect on warfarin sensitivity: CYP2C9 and VKORC1. Developed with human donor genomic DNA, ACCURUN(R) 601 includes the most relevant alleles for warfarin sensitivity and is the only control kit in this market configured as a single package to control for both CYP2C9 and VKORC1 screening. Single package design will enable molecular testing labs to increase test throughput of patient samples, optimizing instrument capacity.

About ACCURUN(R) 610:

The genes associated with thrombophilia have been shown to cause pregnancy complications and infertility. Methylenetetrahydrofolate reductase (MTHFR) may represent an important genetic risk factor for thrombophilia. ACCURUN(R) 610 is a multi-analyte control for genetic screening of MTHFR that includes the most relevant alleles in a single package. Concurrent screening of MTHFR with Factor II and Factor V screening for thrombophilia offers clinicians a more complete picture of the genetic component of the thrombotic phenotype. By using ACCURUN(R) 610 multi-analyte controls, labs can increase test throughput of patient samples, optimizing instrument capacity.

About the Sacred Heart Medical Center Agreement:

The agreement with Sacred Heart Medical Center is an exclusive agreement for the manufacture and distribution of Sacred Heart's multi-analyte synthetic controls for genetic testing for cystic fibrosis and for diseases associated with Ashkenazi Jewish ancestry by SeraCare Life Sciences. The patented method for design, synthesis and production of synthetic nucleic acid reference materials for use in multiplexed assays allows for consistent production in potentially unlimited quantities. These products will now be manufactured at SeraCare's cGMP compliant and ISO 9001 and 13485 certified facilities and, once validated by individual laboratories, can result in a vastly improved and more efficient quality control program. The agreement also includes a license to manufacture and commercialize additional future products under the know-how and intellectual property owned and controlled by Sacred Heart.
