Enzo Biochem Announces NYS Department of Health's Approval of a New Women's Health Infectious Disease Panel

Provides the Ability to Diagnose up to 13 Different Female Infections from a Single Swab Sample Combined with Enzo's Other Approved Panels

Furthers Enzo's Development Program of Robust, Medically Relevant & Affordable Molecular Diagnostic Products and Services Addressing the Clinical Lab Industry's Financial Pressures

Enzo Biochem Inc. ENZ today announced it has received approval of another women's health infectious disease diagnostic panel, which when combined with the Company's previously approved panels, makes for one of the most comprehensive, efficient and affordable diagnostic products and services on the market today. A variety of infections, including sexually transmitted ones, are detected from a single vaginal swab collection via the Company's proprietary, versatile and cost-effective AMPIPROBE^® platform. The announcement results from recent action by the New York State Department of Health granting conditional approval of the new panel's 5 additional tests, complementing the already approved 8 infectious disease tests for a total of 13 organisms being detectable from a single vaginal swab specimen.

Enzo's expanding women's infectious disease menu complements and continues Enzo's decades long offering of women's health tests including a focused cancer offering. In the early 1980s, Enzo brought the first in situ HPV cervical cancer detection system to the marketplace. Enzo's offerings have grown to include immunohistochemistry and gene expression platforms for detecting women's cancers. The latest infectious disease panel follows previously approved AmpiProbe^® real time amplification detection tests for qualitative detection of diseases such as Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis and Candida spp (C. albicans, C. glabrata, C. krusei, C. parapsilosis, C. tropicalis). The newly approved tests for bacterial vaginosis (BV), including Atopobium vaginae, Gardnerella vaginalis, Lactobacillus spp, Megasphera spp and BVAB2, will now make Enzo's women's health panel one of the most comprehensive on the market.

Because of the panel's comprehensiveness and high sensitivity, it quickly and conveniently provides doctors and patients with a result. Where previously a patient may have had to visit her physician multiple times for multiple tests before a diagnosis was reached, causing inconvenience and expense, this panel should reduce those challenges.

Elazar Rabbani, PhD, Enzo Chairman and CEO said, "This underscores that our extensive product and services pipeline is moving along on schedule. We remain intently focused on developing and offering highly effective and affordable diagnostic products and services as solutions to the increasing financial pressures on the clinical laboratory industry from both diminishing reimbursements and the high cost of goods, particularly in the molecular diagnostic arena."

Dr. Rabbani added that, "Since Enzo's inception, we have been committed to advancing healthcare, and providing affordable and reliable diagnostic testing. Enzo is uniquely able to target its integrated diagnostic products and services corporate structure which allows our Company to create cost-effective solutions for the diagnostics market by a process involving technology development, manufacturing, clinical validation and commercialization, while also providing advanced state-of-the-art diagnostic laboratory and reference services. The Company will continue to offer products and services to the clinical laboratory industry at discounts from prevailing market prices."

Enzo's development program includes a line of assays based on its proprietary labelling and detection technologies for different applications such as cancer, infectious disease and immunology. The announcement today is the result of Enzo's concerted use of its proprietary AMPIPROBE^® platform. The next AmpiProbe^® based pipeline panel under development will address the quantification of viral load in serum or plasma specimens. With the Company's AmpiProbe-HCV^® assay for the quantitative detection of Hepatitis C virus already approved, and with the addition of AmpiProbe^® detection of Hepatitis B virus and HIV in development, that panel is well on the way towards additional assays. The Company is also developing a line of products designed to aid pathologists in differentiating the characteristics of various tumors from biopsy specimens. Also in the Company's pipeline is a line of assays based on its proprietary flow cytometry platform for diverse applications in areas such as limitation cancer, immunology and infectious disease. Moreover, many of the Company's existing molecular diagnostic tests can be extended, such as, for example, extending the detection of vaginal HPV in women, to detecting HPV in oral and anal locations in men and women. Enzo's molecular-based products and services target a domestic laboratory market currently estimated to be in excess of $3 billion in revenues.
