Antibody molecular farming in plants and plant cells

`Molecular Farming' is a novel approach to the production of pharmaceuticals, where valuable recombinant proteins can be produced in transgenic organisms on an agricultural scale. Plants have been traditionally used as a source of medicines, but the use of transgenic plants in molecular farming represents a novel source of molecular medicines that include plasma proteins, enzymes, growth factors, vaccines and recombinant antibodies. Until recently, the wide use of these molecular medicines was limited because of the difficulty in producing these proteins outside animals or animal cell cultures. The application of molecular biology and plant biotechnology in the 1990s showed that many molecular medicines could be synthesised in plants. The goal of this Molecular Farming technology is to produce pharmaceuticals that are safer, easier to produce and less expensive than those produced in animals or microbial cultures. Here, we examine the production of recombinant antibodies by Molecular Farming.
