EMD Launches First Bead-Based Multiplex Assays Using EpiTag(TM) Technology from Epitome Biosystems, Inc.



    EMD Chemicals, Inc. (EMD), a subsidiary of Merck KGaA, Darmstadt,
    Germany, and Epitome Biosystems, Inc, announced today that EMD has
    launched WideScreen(TM) EpiTag(TM) ERK Pathway Assays, the first wave
    of bead-based, multiplex assays using EpiTag(TM) Technology licensed
    from Epitome Biosystems. The new line of assays will enable
    researchers to make quantitative, highly multiplexed measurements of
    important cell targets, greatly facilitating drug discovery efforts.

    EMD´s Novagen WideScreen Group and Epitome Biosystems collaborated
    to develop immunoassay panels using a novel, powerful technology
    platform for the multiplex quantitation of phosphorylated proteins.
    WideScreen EpiTag(TM) Assays, performed on the xMAP(R) Technology
    based line of instrument platforms from Luminex Corporation (Nasdaq:
    LMNX), utilize EpiTag(TM) Technology, a highly targeted measurement
    platform for multiplex protein assays. The first in a series of
    validated assay panels is available globally through the international
    sales and distribution network of the EMD/Merck group.

    "WideScreen(TM) EpiTag(TM) Assays detect key signaling events in
    the ERK pathway from both human and mouse samples," said Lisa Johnson,
    Novagen and Calbiochem Business Unit Manager with EMD. "These products
    demonstrate the power of EpiTag Technology and we look forward to
    developing more EpiTag Assays with Epitome Biosystems."

    ERK pathway protein levels and phosphorylation are deregulated in
    many types of cancer and are considered strong candidates for the
    development of therapeutic compounds. These assays will enable
    researchers to determine the effect of candidate compounds on multiple
    analytes, to allow a better understanding of on- and off-target
    effects.

    "Working with EMD to commercialize these EpiTag-based assays is an
    important step in building a comprehensive set of products to provide
    researchers with powerful approaches for making reliable cell- and
    tissue-based multiplex measurements," said Neal Gordon, Ph.D.,
    President, Epitome Biosystems. "These products address the market´s
    expressed need to obtain absolute, quantitative measures of protein
    phosphorylation in a highly targeted manner."

    EMD and Epitome Biosystems have ongoing collaborations to develop
    EpiTag Assays for additional targets in the ERK pathway and for
    membrane proteins, which traditionally have been very difficult to
    measure.
