We want to help improve lives by accelerating our partners’ research and lowering the costs in the development of human and animal health and consumer products.

We believe that we are leading the change for the future

Current increasing demand across industries for bioactive molecules cannot be met with today’s production platforms alone. Our expression technology offers a robust alternative to traditional systems and can help tackle delays due to lack of conventional manufacturing capacity or technical challenges to deliver complex biomolecules quickly and more cost-effectively, reducing the time from clinic to market.

Leaf Expression Systems is an established contract research and product development company working to serve the global life sciences, consumer product, agribiotech and cellular food industries. Our expert team specialise in producing high value proteins and biomolecules for use within research and product development.

Our Supravec® Technology

SupraVec is our proprietary expression technology, it 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, including antibodies, vaccines and complex natural products can be produced at speed and on a large scale.

Our system is directly scalable so we can quickly calculate costs and yields based on a feasibility study, it’s as simple as just growing more plants!
