Leiden, The Netherlands, 16 January 2007 - Dutch biotechnology company Crucell N.V. (Euronext, NASDAQ: CRXL) announced today that it has signed a non-exclusive STAR(TM) research license agreement for the production of monoclonal antibodies with Bagsvaerd, Denmark-based Novo Nordisk A/S.

Novo Nordisk A/S intends to evaluate the STAR(TM) technology using its proprietary mammalian CHO cell line along with its antibodies. Under the terms of the agreement, Novo Nordisk A/S will pay a license issuance fee, a success-based fee and annual maintenance fees provided the license is extended upon evaluation. Financial details of the deal were not disclosed.

About Star Technology
Crucell’s STAR(TM) technology is useful for increasing production of recombinant antibodies and therapeutic proteins on mammalian cell lines. STAR(TM) technology supports high yield antibody and protein production. Using Crucell’s STAR(TM) technology, high levels of protein can be generated. This has been demonstrated in several CHO derivatives for numerous proteins and different antibodies. Under standard non-optimized cell culture conditions using commercially available medium, specific productivity levels ranging between 25 and 50 pg/cell/day are easily achieved with screening of only up to 25 clones. Therefore Crucell’s STAR(TM) technology is also ideal for stable bulk transfections to rapidly obtain adequate levels of protein for immunization, target discovery processes, protein characterization, or optimization and validation of downstream processes such as protein purification.
