                GLOBAL REAGENT MANUFACTURER AND MARKETING COMPANY
                                     -------
       ACQUISITION WILL BROADEN ENZO'S LIFE SCIENCE ACTIVITIES AND EXPAND
          PRODUCT DEVELOPMENT, PRODUCTION AND DISTRIBUTION CAPABILITIES

NEW YORK, NY, May 30, 2007 - Enzo Biochem,  Inc. (NYSE:ENZ) announced today that
its wholly owned subsidiary,  Enzo Life Sciences,  Inc., has signed a definitive
agreement  to acquire  Axxora Life  Sciences,  Inc.,  a privately  owned  global
manufacturer and marketer of life sciences research products,  for approximately
$16.3 million in cash. Upon completion of the acquisition,  Axxora will become a
wholly owned  subsidiary  of Enzo Life  Sciences and will greatly  expand Enzo's
life sciences product development, production and marketing capabilities.

        Axxora had  revenues  of  approximately  $16  million  and 60  employees
worldwide  in  2006.   Axxora  has   wholly-owned   subsidiaries  in  the  U.S.,
Switzerland,  Germany  and the United  Kingdom,  as well as branch  offices  and
distributors  located in other major  markets,  and  benefits  from a history of
profitability.

        Axxora's ALEXIS(R) Biochemicals division, based in Lausen,  Switzerland,
is  an   internationally   recognized  brand  and  an  acknowledged   leader  in
manufacturing,  in-licensing and  commercializing  high-quality  reagents in key
research areas.  Axxora's  Apotech(R)  division,  also based in Switzerland,  is
engaged in the  discovery,  development  and  production  of new products in the
field of immunology, apoptosis and inflammation. Axxora's electronic marketplace
enables customers to purchase research reagents from internationally  recognized
manufacturers covering all areas of the life sciences research reagents field.

        "Axxora  enjoys  a  strong   international   position  as  a  developer,
manufacturer and distributor of reagents  addressing  immunological and cellular
research  and  the  biochemical  industries.   We  expect  it  to  prove  highly
synergistic  with regard to the  activities of Enzo Life  Sciences,"  said Barry
Weiner,  President of Enzo.  "In addition to broadening  our revenue  base,  the
acquisition   will   significantly   expand   our   distribution    capabilities
internationally  providing  Enzo with a base to market its  products  throughout
Europe and the rest of the world. It complements  our Life Sciences  business in
many  ways.  Axxora  will  have  access  to Enzo  Life  Sciences'  technological
capabilities,  and unique platforms particularly in the growing areas of nucleic
acid  technology  labeling and detection,  where Enzo holds a solid  proprietary
position.  Furthermore,   Axxora's  strong  European  presence  and  operational
capabilities,   along  with  its  state-of-the-art  electronic  information  and
ordering marketplace,  which encompasses a wide range of diverse products, makes
this  transaction  especially  attractive.   Finally,  we  view  this  strategic
transaction  as the  beginning of a program to build  critical  mass in our Life
Sciences division via acquisition as well by organic growth."



        Carl W.  Balezentis  Ph.D.,  President of Enzo Life Sciences,  commented
that "Axxora has a proven leadership team and a strong  international  brand. We
see  significant  growth  opportunities  through  Axxora's  broad  international
presence, the expansion of its reagent production,  marketing capabilities,  and
its integration  with Enzo Life Sciences'  proprietary  position in this dynamic
field."

        "We are excited  that our well  established  life  sciences  business is
joining  an  organization  that  shares  our  focus  on  providing   innovative,
high-quality  research  reagents," said Georges Chappuis,  Ph.D.,  President and
Chief Executive Officer of Axxora.  "With our senior management team,  including
the heads of all our units,  remaining in place  following the  acquisition,  we
believe that the combined  organization will be strongly  positioned to maximize
new growth opportunities  integrating Enzo's strong innovative research programs
with Axxora's international marketing capabilities"

        The  acquisition  is  subject to  customary  closing  conditions  and is
expected to close in early June 2007.
