                      ENZO BIOCHEM ANNOUNCES THIRD QUARTER
                        AND NINE MONTHS OPERATING RESULTS
                               ------------------

                  Board of Directors Declares 5% Stock Dividend
                                 ---------------

FARMINGDALE, NY, June 16, 2003 - Enzo Biochem, Inc. (NYSE:ENZ), a leading
biotechnology company specializing in gene identification and genetic and immune
regulation technologies for diagnostic and therapeutic applications, today
reported operating results for the third quarter and nine months ended April 30,
2003.

         The Company also reported that its Board of Directors has declared a 5%
stock dividend payable July 14, 2003, to shareholders of record of June 30,
2003. Enzo said that the stock dividend was an expression of the Company's
confidence in its activities.

Operating Results

         For the third fiscal quarter ended April 30, 2003, total operating
revenues amounted to $11.6 million, compared with $15.0 million in the
corresponding year-earlier period. Net income amounted to $1.2 million, or $0.04
per share fully diluted, compared with $2.6 million, or $0.08 per share fully
diluted, a year ago. The per share figures are adjusted for the newly declared
stock dividend.

         Total operating expenses declined to $10.0 million, from approximately
$11.0 million in the corresponding year ago period, reflecting, among other
things, a reduced provision for uncollectible accounts receivable and lower R&D
expenditures during the quarter. General and administrative expenses decreased
to $2.3 million, as compared to $3.2 million a year ago, and as a percentage of
operating revenues declined to 20%. G&A costs primarily resulted from reduced
legal expenses.

         Fiscal nine-month operating revenues increased to $42.1 million, from
$40.2 million in the corresponding year-ago period. Total operating expenses for
the year to date were $32.7 million, compared with $32.6 million. Net income for
the nine months increased to $6.4 million, or $0.21 per share fully diluted,
compared with $5.2 million, or $0.17 per share fully diluted in the
corresponding year-earlier period. The per share figures are adjusted for the
declared stock dividend.

         On April 30, 2003, working capital amounted to $99.7 million. Cash and
equivalents totaled $79.1 million, approximately $12.0 million greater than at
the end of fiscal 2002. There is no debt.

         "The decline in results for the three months resulted from reduced
orders of research products from Life Sciences distributors," said Barry Weiner,
Enzo's president. "Despite lower revenue for the quarter, net income for the
nine months is up nearly 23% over the prior year. Cash flow from operations


                                    - more -

was $3.6 million in this quarter and $12.9 million for the nine months. As we
have indicated previously, there can be no assurances that, due to general
economic conditions and variations in ordering patterns, the level of revenue
for various periods will remain the same. We are pleased that Enzo Clinical Labs
continued to post increased revenues, profits and margins and, with a number of
new life science products about to be introduced and four therapeutic products
in the process of clinical evaluation, we remain very encouraged regarding the
overall outlook of the Company."

Enzo Life Sciences

         Revenues at Enzo Life Sciences in the third quarter amounted to $4.2
million, compared with $8.2 million a year ago. Operating profits for the three
months decreased to $1.6 million versus $5.2 million. For the nine months
revenues increased to $20.6 million from $18.3 million. Operating profits for
the nine months for the Division increased to $11.3 million from $10.4 million.
Enzo Life Sciences has completed development and expects early this summer to
release additions to its GeneBeam(TM) cDNA Labeling Kits for microarray analysis
of gene expression. These kits meet the needs of researchers by delivering
strong, clear signals with negligible background "noise." Such features are
essential for array scanning and data analysis. These GeneBeam(TM) Labeling Kits
utilize Enzo's proprietary cyanine dye nucleotides and are designed to be used
in a straightforward, ready-to-use format. This fall the Company anticipates the
introduction of a novel amplification system for genetic analysis that will be
marketed to pharmaceutical and academic researchers. It would facilitate the use
of minute genetic material with a high degree of integrity, which is not
currently available. A patent application is pending on this product.


Enzo Clinical Labs

         At Enzo Clinical Labs, fiscal third quarter revenues increased to $7.5
million, compared with $6.8 million in the corresponding year-ago period.
Results benefited from expanded marketing and higher priced esoteric diagnostic
tests. Operating profits for the quarter increased to $850,000 from $36,000. For
the nine months, revenues were $21.5 million as compared to $21.9 million a year
ago, and operating profits increased to $2.4 million as compared to a loss of
$0.4 million a year ago. Enzo Labs recently acquired exclusive rights in the
metropolitan New York area for a new test, AspirinWorksTM, which detects aspirin
resistance by measuring an individual's response to aspirin dosage. While
millions of Americans are prescribed a daily dosage of aspirin as a preventative
measure against heart attack, recent reports indicate that as many as 25% of
these individuals may be resistant to aspirin, which could mean they are
non-responsive to aspirin's benefits or that the dosage they are receiving is
not effective. Enzo Clinical Labs also has in Beta testing a suite of physician
connectivity products that is expected to vastly increase the flexibility with
which physician clients will be able to place laboratory orders and receive
results. The proprietary applications will run on either a local computer on the
physician's internal network or as a web-based application. The program,
EnzoDirect(TM) Physicians' Connectivity Solution, is expected to be on line in
July. In addition, the laboratory was awarded an Accreditation with Distinction
from the College of American Pathology for the level of "excellence of the
services provided."

Enzo Therapeutics

         Enzo Therapeutics, as announced previously, has initiated a Phase II
randomized double blind clinical trial of the Company's proprietary study drug
for managing Crohn's Disease. The highly favorable results of the Phase I trial
of this treatment were presented at a digestive disease conference in Florida
and indicated that, all 10 subjects showed a clinical response, with seven
achieving clinical remission, during the course of the trial. No
treatment-related adverse effects were noted in any of the subjects. Also
underway is planning for the initiation of a double-blind multi-nation Phase II
clinical trial of EHT899, the Company's medicine for hepatitis B
virus-associated chronic hepatitis. Enzo is

completing a program to begin manufacture of EHT899 for the trial. Plans are
also proceeding for further studies of ECH18, a formulation to manage hepatitis
C virus-associated hepatitis.

The Phase I study of Enzo's StealthVector(R) HGTV43 gene medicine for HIV-1
infection is now in the safety follow-up phase and the Company is looking to
proceed with a multi-site Phase I/II trial.
