Tobacco-based Expression System

Tobacco, as a plant-based bioreactor, has the ability to manufacture a wide range of proteins including antibodies and vaccines. Supported by our advanced technology platform and experienced scientists, Creative Biolabs offers tobacco-based antibody expression services to accelerate your programs and meet your study milestones.

Introduction of Tobacco-based Expression System

Plant bioreactor is a production system that utilizes plant cells, tissues, organs, and whole plants as "factories" to produce biological preparations such as medicinal proteins, enzymes for industry and agriculture, special carbohydrates, biodegradable plastics, lipids, and other secondary metabolites through genetic engineering. Tobacco has been and will continue to be major bioreactors that have several technical advantages. Firstly, tobacco is susceptible to genetic modification and also provides various methods of expressing proteins of interest, including transient expression and stable expression. In addition, tobacco has leaf biomass as high as 100 tons per hectare and high levels of soluble protein, which promote it to be an efficient bioreactor. Finally, tobacco-based antibody expression system is environmentally friendly, as the protection against food-chain contamination and bio-containment. These characteristics made tobacco particularly well suited for plant-based bioreactor to product biopharmaceutical proteins.
