2020/3/26 Animal-Free Expression - Profacgen Animal-Free Expression Plant expression systems are used when animal-free recombinant protein products are required. Compared to traditional microbial or animal cell systems, the animal- free plant expression systems greatly reduce the risk of contamination with animal- origin pathogens. Furthermore, plant production possesses superior advantages in storage, distribution and scale-up. Many plant species have been developed as protein expression systems, such as rice, tobacco, and Arabidopsis thaliana. To obtain transgenic plants for the stable expression of proteins, plant virus and bacterium are utilized to deliver the desired gene into plant hosts. The most commonly used delivery systems include tobacco mosaic virus (TMV) and Agrobacterium. https://www.profacgen.com/Animal-free-Expression.htm 2/6
2020/3/26 Animal-Free Expression - Profacgen Animal-free expression system can be used to express large quantities of proteins. Many plant species are developed as protein expression systems, such as tobacco, rice and Arabidopsis thaliana. Profacgen provides a high capacity rice grain (Oryza sativa L.) expression system. It is a robust and flexible expression system that allows the expression of both short peptides (shorter than 100 amino acids) and large recombinant proteins (up to 1000 amino acids). The rice grain system uses rice endosperm cells as the host and rice farming for scaling up production. The rice endosperm specific expression system Features High yield (from 2g/kg to 10g/kg of rice seed) High scale-up capability Easy storage and distribution (rice seed containing target protein or peptide https://www.profacgen.com/Animal-free-Expression.htm 3/6
