ProCellEx®: Our Proprietary Protein Expression System
ProCellEx® is our proprietary platform used to produce and manufacture recombinant proteins through plant cell-based expression systems.
Our platform is a proven alternative to the mammalian cell-based production technology (the most common form of recombinant protein production), overcoming many of its weaknesses while offering significant production, regulatory, and cost benefits.
ProCellEx® consists of a comprehensive set of proprietary technologies and capabilities, including the use of advanced genetic engineering and plant cell culture technology, enabling us to produce complex, proprietary, and biologically equivalent proteins for a variety of human diseases.
Our protein expression system facilitates the creation and selection of high-expressing, genetically-stable cell lines capable of expressing recombinant proteins.
