ROCKVILLE, Md., Sept. 12 BioReliance Corporation, aleading contract services organization for the biopharmaceutical andpharmaceutical industries, has contracted with Gentronix to offer theirGreenScreen HC in vitro assay as a major part of BioReliance's portfolio ofgenotoxicity screening services. GreenScreen HC, in conjunction with Ames IIassays, allows pharmaceutical companies to test for genotoxic potentialearlier in the preclinical development process, using only a few milligrams oftest compound as opposed to the gram quantities required by current ICHregulatory tests.

John Nicholson, Chairman and CEO of Gentronix, comments, "We are delightedto complete this agreement with BioReliance, a company regarded as a globalleader in genetic toxicology testing services." "This new high-throughputassay from Gentronix furthers BioReliance's ability to meet customer demandfor faster and more effective genotoxic screening services," adds DavidBruning, Senior Director, Toxicology Operations at BioReliance. "TheGreenScreen HC and Ames II assays, when combined, offer highly predictive andsensitive detection of genotoxic compounds while minimizing false positivesseen with other in vitro assays, accelerating the development process."

GreenScreen HC is a unique human cell-based genotoxicity screening assaythat links the regulation of the human Growth Arrest and DNA Damage (GADD45a)gene to the production of Green Fluorescent Protein (GFP). Cells that haveincurred DNA damage upon exposure to a test compound express higher levels ofdetectable GFP.

GreenScreen HC only requires 1 mg of starting material to demonstrate highspecificity, in contrast to other in vitro genetic toxicology assays thatoften provide false positive results. GreenScreen HC is able to detectmultiple mechanistic classes of genotoxic agents, including aneugens, and iseasily adapted to automatic robotic platforms.
