Epitome Biosystems Completes Development of Multiplex Assays for EMD Biosciences Inc.

January 31, 2007

Waltham, MA, and Madison, WI, January 31, 2007 – Epitome Biosystems and EMD Biosciences Inc. announced today the successful completion of a collaboration to develop multiplex assays to measure phosphorylation of cell signaling proteins using Epitome’s EpiTag™ technology. Epitome developed custom antibody and peptide reagents to enable quantitative protein measurements of selected targets for EMD Biosciences. This completes the first commercial partnership for Epitome. Products resulting from this collaboration will be manufactured, marketed and sold for research applications on a world-wide basis by EMD Biosciences Inc. through its Novagen brand.

“Achieving this important product development milestone serves as further validation for our EpiTag™ technology platform and, importantly, will lead to the imminent commercial launch of products,” said Neal Gordon, Ph.D., President, Epitome Biosystems. “These efforts are contributing to our goal of generating a comprehensive product suite to assess biological function with numerous applications in drug discovery and development.”

“The EpiTag™ technology facilitates the rapid development of robust multiplex immunoassays, including those that can interrogate novel phosphorylated targets” said Graham Scott, Ph.D., Senior Director (Biodiscovery) of EMD Biosciences Inc. “This joint development project with Epitome has clearly demonstrated the considerable power and utility of this platform technology, and we are excited about commercializing these innovative assays.”

Epitome’s proprietary EpiTag™ technology enables the reliable and cost-effective development of assays for the quantitative measurement of proteins in “sandwich” assay formats. The flexible technology has been applied to develop antibody array products for broad profiling of intracellular signaling and products for highly quantitative protein measurements in multiplex formats. The phosphorylation state of intracellular signaling proteins is an important indicator of biological function and is useful in the characterization of disease. Although sandwich antibody pairs provide highly specific and sensitive protein measurements, they are difficult to develop and limited in availability. Epitome’s approach overcomes these limitations and facilitates rapid assay development and targeting of novel measurements.
