CRUCELL TO PRESENT PRE-CLINICAL RESULTS FOR H5N1 VIRUS TREATMENT

LEIDEN, THE NETHERLANDS, SEPTEMBER 14, 2007 - Dutch biotechnology company
Crucell N.V. (Euronext, NASDAQ: CRXL, Swiss Exchange: CRX) today announced that
its researchers have discovered a monoclonal antibody that is active against
H5N1 avian influenza. The studies will be presented at the 5th International
Bird Flu Summit scheduled for September 27 and 28 in Las Vegas, Nevada.

Crucell researchers produced antibodies in PERC6(R) cells and tested their
biophysical and immunological properties.

"Using phage  display  technology a set of human  monoclonal  antibodies  active
against a broad range of distinct  H5N1  strains was  developed,"  said  Crucell

antibodies to prevent infection as well as to prevent and cure disease caused by
H5N1 virus in mice."

Crucell will provide more  information  about the research  findings  during the
two-day conference in Las Vegas.
