Plant-grown therapeutic proteins

Medicine, grown in light.

We coax living chloroplasts into producing the proteins modern therapies are built from — at field scale, without a single steel bioreactor or animal input.

STAGE 01 — GROW

It starts in a leaf.

We grow ordinary tobacco-relative plants in vertical light farms. Their chloroplasts — the same engines that turn sunlight into sugar — carry an extra instruction we wrote into their DNA: build our protein.

STAGE 02 — EXPRESS

The cell reads the code.

As the plant photosynthesises, each chloroplast transcribes that instruction and folds the target protein in place. One unwound strand becomes a working template — millions of copies per leaf, powered entirely by light.

STAGE 03 — EXTRACT

We harvest, gently.

Leaves are pressed and the protein is released into a water-based buffer — no harsh solvents. A single chromatography pass separates our molecule from plant matter at better than 99% purity.

STAGE 04 — DELIVER

Packed for the patient.

The purified protein is formulated into stable, shelf-ready doses — packed into capsule and vial formats that survive the supply chain without a cold-storage tail.
