Market Drivers of the Transient Protein Expression Market

Increasing Applications of Protein Expression Systems

Animal and plant cell-based transient protein expression systems have been in use for the last three decades. Significant advancements in proteomics in recent years have resulted in the availability of newer recombinant protein varieties. The practicality and reproducibility of transient protein expression in animal and plant cells encourage research and development activities to extend their applications in human cell lines. Many contract research and development organizations as well as biopharmaceutical companies, among others, have focused their efforts on incorporating transient protein expression into their production processes. This type of expression system allows them to use different genes to create recombinant proteins without relying on the development of stable cell lines.

The temporary protein expression process finds widespread application in the manufacturing of growth factors, cytokines, hormones, blood products, modified human proteins, and monoclonal antibodies. Moreover, the creation and use of effective bioprocessing techniques have become essential for the commercial synthesis of recombinant proteins with significant therapeutic value. Recent developments in the field of bioprocessing are being applied to provide efficient methods for generating recombinant proteins. Modern Quality by Design concepts, continuous upstream processing, continuous chromatography, integrated continuous bioprocessing, high-throughput devices for efficient bioprocess optimization, disposable systems, and process analytics technologies for higher yields of high-quality products are among the recent developments that propel the adoption of transient protein expression systems.

Plant-Based Expression Systems for Therapeutic Protein Production in Emerging Countries to Create Market Opportunities

The use of microbial or mammalian cell-based expression systems has been a common practice in recombinant protein production processes; however, plant-based expression has been promoted as a cost-effective, scalable, safe, and sustainable alternative in recent years. Advancements in transient expression methods have resulted in a significantly shortened duration of protein synthesis and the improved yield of recombinant proteins in plant-based systems. A shift in consumer preference toward plant-based products compels pharmaceutical and biopharmaceutical companies to focus on plant-based synthesis of therapeutic proteins. The use of plants has excellent potential for improving yields of proteins that can be administered for the prevention or treatment of human and animal diseases. The use of therapeutic proteins is likely to surge in the healthcare sector in the coming years due to the ongoing restructuring of regulatory frameworks and growing awareness about transient protein expression in plants. Maximum scale?up possibility, low growth costs, complex protein production ability, low contamination (especially involving human pathogens) risks, and optimized growth conditions are among the key advantages associated with carrying out transient protein expression in plants. Moreover, plants are considered safer compared to other expression systems as they do not produce endotoxins and cause less harm to humans. Thus, plant-based expression systems for therapeutic protein expression are emerging as vital opportunities for the transient protein expression market growth during the forecast period.
