About the EB66® line

The EB66® cell line, derived from duck embryonic stem cells, presents unique industrial and regulatory characteristics such as long-term genetic stability, immortality and cell growth to high cell densities in suspension in a serum-free medium (>20 millions cells/mL).

The BMF (Biologics Master File) for the registration of the EB66® cell line with the FDA (U.S. Food and Drug Administration) was filed on June 27, 2008.

The EB66® cell line is currently used or being tested by 75% of the major players in vaccines. VIVALIS has furthermore demonstrated that the EB66® cell line can be easily genetically modified, permitting the expression of recombinant proteins of potential interest. Moreover the glycosylation profile of monoclonal antibodies produced through EB66® cell lines is similar to the glycosylation profiles of human monoclonal antibodies with the added benefit of being distinguished by reduced fucose content. This latter characteristic is known to be associated with a higher level of antibody cytotoxic activity, particularly useful in the treatment of cancer cells.
