Transient Expression of Antibodies in Plants Using Syringe Agroinfiltration

Abstract

The improvements in agroinfiltration methods for plant-based transient expression now allow the production of significant amounts of recombinant proteins in a matter of days. While vacuum-based agroinfiltration has been brought to large scale to meet the cost, speed and surge capacity requirements for vaccine and therapeutic production, the more accessible and affordable syringe agroinfiltration procedure still represents a fast and high-yielding approach to recombinant protein production at lab scale. The procedure exemplified here has proven its reproducibility and high-yield capacity for the production of proteins with varying levels of complexity, including monoclonal antibodies.
