Transient co-expression for fast and high-yield production of antibodies with human-like N-glycans in plants.
Plant-based transient expression is potentially the most rapid and cost-efficient system for the production of recombinant pharmaceutical proteins, but safety concerns associated with plant-specific N-glycosylation have hampered its adoption as a commercial production system. In this article, we describe an approach based on the simultaneous transient co-expression of an antibody, a suppressor of silencing and a chimaeric human beta1,4-galactosyltransferase targeted for optimal activity to the early secretory pathway in agroinfiltrated Nicotiana benthamiana leaves. This strategy allows fast and high-yield production of antibodies with human-like N-glycans and, more generally, provides solutions to many critical problems posed by the large-scale production of therapeutic and vaccinal proteins, specifically yield, volume and quality.
