Transgenic expression of therapeutic proteins in Arabidopsis thaliana seed.
The production of therapeutic proteins in plant seed augments alternative production platforms such as microbial fermentation, cell-based systems, transgenic animals, and other recombinant plant production systems to meet increasing demands for the existing biologics, drugs under evaluation, and undiscovered therapeutics in the future. We have developed upstream purification technologies for oilseeds which are designed to cost-effectively purify therapeutic proteins amenable to conventional downstream manufacture. A very useful tool in these endeavors is the plant model system Arabidopsis thaliana. The current chapter describes the rationale and methods used to over-express potential therapeutic products in A. thaliana seed for evaluation and definitive insight into whether our production platform, Safflower, can be utilized for large-scale manufacture.
