Enzo Biochem's Clinical Lab Takes Major Step in Becoming National Provider of Predictive Diagnostics

Pennsylvania Grants Lab License to Operate, With Several Others Pending

NEW YORK--(BUSINESS WIRE)-- In the first of several moves to expand the Company's position as a national provider of esoteric and high value diagnostics, Enzo Biochem, Inc. (NYSE:ENZ) announced today that its Enzo Clinical Labs division has been awarded a license for doing business in the Commonwealth of Pennsylvania, the first of several for which it has applied.

"Patient care is moving increasingly to predictive diagnostics utilizing markers and gene based programs, and Enzo Clinical Labs, owing to its highly regarded New York State certification, is increasingly focused on developing into a national leader for the application of esoteric testing and the diagnosis of these specimens," said Kevin Krenitsky, M.D., President of the Clinical Labs Division. "The granting of our license by Pennsylvania is thus a significant step in our ability to solicit business and accept specimens from locations other than the metropolitan New York area, where traditionally most of our business has derived."

The Lab, headquartered in Farmingdale, NY, currently has pending license applications with the states of Maine, Maryland and California.

"In recent years, our Company has invested heavily in the Clinical Lab, expanding our physical plant, adding advanced diagnostic equipment, and installing state of the art accounting systems and communications functionality, to speed accurate and prompt reports to our physician clients," said Barry Weiner, President of Enzo Biochem. "Most notably, we have invested in top level professionals, attracting to the Lab highly regarded pathologists and experienced leaders in the diagnostics field.

"While we continue to perform routine testing, our expanded capabilities will enable our diagnostic laboratory facilities on Long Island to provide what we expect will be an increasing level of higher performance tests sent to us from physicians in all parts of the country," added Mr. Weiner.

Among the unique clinical diagnostic tests in development by Enzo are the ColonSentry(TM) colon cancer risk-stratification assay, multiplex DNA sequencing, alternative amplification/detection methods for pathogens, and cytogenetic tests for cancer using Enzo proprietary probe technology.
