Plant-based production of xenogenic proteins

Foreign protein production in transgenic plants has been successful, from t he generation of transgenic plant lines to the marketing of purified protei ns. Antigenic proteins from disease organisms, monoclonal antibodies raised against antigens of disease organisms, and proteins with industrial proces s applications have been produced and tested. For vaccines, clinical trials in humans and feeding trials in animals are in progress to demonstrate the ir efficacy. For industrial proteins, high expression and downstream proces sing efficiency are key concerns, with application and test market trials i n progress.
