High Quality | Rapid | Scalable | Competitive

We offer services in protein expression production. We pride ourselves on being experts in the expression and the production of proteins, including antibodies and allergens, enzymes and vaccines. Our protein production services use our plant-based transient expression technology and as a result, delivers rapid, scalable production of quality products that are competitive to produce.

It is our goal at Leaf Expression Systems to help improve lives. We aim to do this by accelerating clients’ research and lowering costs in the development and manufacture of therapeutic drugs, vaccines, and diagnostics.

Unlike more conventional protein expression systems, we believe our technology can deliver drugs more quickly and more cost-effectively, thereby reducing the time from clinic to market. Not only does this help to reduce the time it takes to get new drugs to patients and at a cheaper cost but can cut the time to market by at least 7 months.



About Us

Our Technology

Plant-based expression systems have a range of technical advantages. These include; insertion gene size, yield, propagation, protein assembly and folding accuracy, product quality and homogeneity, distribution and storage temperature, together with scale-up, speed and flexibility this leads to significant reductions in manufacturing costs of goods and above all, costs to patients.

The SupraVec® system allows for the rapid simultaneous production of multiple gene products in a controlled and coordinated manner within the tissues of plants. Using gene synthesis and modular vectors, new products such as vaccines, antibodies or enzymes can be rapidly produced on a large scale therefore making it well suited to be able to rapidly respond to emergencies like pandemics.
