<Not only is the technology fast, cheap and safe, but Levy said there's reason to expect that the plant-grown antibodies will generate a stronger immune response than those made in animal cells. Both plant and animal cells attach sugars to antibodies and other proteins during biochemical processing, but the plant and animal sugars are different. The difference might prompt a more robust immune response to plant-grown antibodies, Levy said.>

There is a balance. If the antibodies become too imunogenic, they could be cleared prior to binding the desired targets.
