Foreign protein production in plant tissue cultures

Foreign proteins synthesised by plants are now in the marketplace, and clin ical trials for plant-derived therapeutic proteins are underway. Economic a nalysis of plant production systems has helped identify the types of protei n that would be most suitable for manufacture using tissue culture methods. The major advantages associated with in vitro plant systems include the ab ility to manipulate environmental conditions for better control over protei n levels and quality, the rapidity of production compared with agriculture, and the use of simpler and cheaper downstream processing schemes for produ ct recovery from the culture medium.
