jesse, I've wondered about this myself, although I don't know enough about it to do anything but wonder. From the Crucell website:

"Proteins

Recombinant Proteins – Recombinant proteins, such as blood factors, can be produced efficiently and safely on the PER.C6® cell line.

Antibodies – MAbstract® technology is used to identify strong binding and neutralizing antibodies for specific disease targets. Antibodies discovered in this way can then be produced on PER.C6® technology."
