Cucumber Mosaic Virus Inducible Viral Amplicon (CMViva) Expression System

技术优势: CMViva system using transient production: Short timeframe from gene to product Can use non-transgenic plant materials that might be available at a large scale and relatively inexpensive for recombinant protein production CMViva system using stably transformed cell cultures in bioreactors: Plant cells can be grown in inexpensive, chemically defined media devoid of any animal derived media components Containment which allows reproducibility and optimization of growth and induction conditions Ease of purification for secreted products Both methods provide: Production of safe human therapeutics and vaccines that are free from mammalian viruses/pathogens Production of proteins with post-translational modifications and complex glycosylation that is similar to mammalian systems.

技术应用: Rapid, large-scale, and cost-effective production of functional human therapeutic proteins and vaccines or other commercially important proteins

详细技术说明: Plant cell cultures and transgenic plants have been developing as a potential platform for production of recombinant proteins, particularly playing an increasingly important role in production of human therapeutics. However, efficient expression systems that can be tightly regulated are currently lacking for plant-based protein expression. Researchers at University of California, Davis have developed a novel protein expression system, called Cucumber Mosaic Virus Inducible Viral Amplicon (CMViva), to inducibly and efficiently produce recombinant proteins in transgenic plant cell cultures. This novel protein expression system can produce recombinant proteins in plant-based systems using either transient expression in whole plants, plant tissues or plant cell cultures (using wild type, non-transgenic host tissues), stably transformed plant cell cultures in bioreactors or in transgenic plants.
