Plant-Based Expression Systems Market is projected to grow at an annualized rate of about 12% during the period 2023-2035 



Plant-Based Expression Systems

Given the growing clinical pipeline of biologics and advantages offered by plant-derived therapeutics, such as high scalability and eukaryotic modification of proteins, plant-based expression systems have emerged as an optimal drug development platform

Roots Analysis has announced the addition of “Plant-based Biologics and Expression Systems Market, 2022-2035” report to its list of offerings.

Plants produce high-value recombinant proteins that can be used for the preparation of pharmaceutical therapeutics, as well as non-pharmaceutical products; these proteins find applications in the development of antibodies, vaccine antigens, enzymes, growth factors, research or diagnostic reagents and cosmetic ingredients. Plant-host engineering serves as a method for the production of proteins with distinct and uniform post-translational modifications (PTMs), creating opportunities for the development of biologics having relatively increased efficacy, as compared to their mammalian cell counterparts.
