The technique of creating an artificial protein, known as a heterologous protein, involves introducing recombinant DNA into a host cell, a process that exemplifies the essential biological function of protein expression. This fundamental process is so critical that even the simplest prokaryotic organisms dedicate nearly 80% of their energy and over half of their dry weight to it. Cells, as the basic building blocks of life, must synthesize proteins using the instructions encoded in their DNA, as these proteins determine their unique shapes and structures. According to the fundamental dogma of molecular biology, genetic information flows from DNA to RNA through transcription and is then translated into proteins, highlighting the intricate connection between genetics and cellular function.
In June 2024, the Broad Institute unveiled a groundbreaking epigenetic editing method capable of permanently silencing the gene responsible for producing prion proteins in the brain using molecular tools. This innovative approach, which involves a single intravenous injection of a modified adeno-associated virus (AAV), has shown promising results in animal studies, reducing prion protein levels by over 80%, and potentially paving the way for new treatments for prion diseases. In a related development, the FDA approved fifty new medications in 2021, including fourteen biologics—such as monoclonal antibodies, pegylated proteins, hormones, and enzymes—all of which require protein expression. Notably, the approval of upheld, a co-packaged preventive treatment, and various monoclonal antibodies like tocilizumab and sotrovimab for COVID-19 further highlighted the importance of protein biologics. As the FDA was expected to approve several additional medications in 2022, the growing demand for these products has significantly increased the need for protein expression goods and services, driving market expansion.
The Protein Expression Market is segmented based on the type of protein expression system, protein expression-related offerings, application area, end-users, and type of operation. Based on the type of protein expression system, the market is divided into algal, cell-free, insect, mammalian, prokaryotic, and yeast. Based on the Protein Expression-related Offerings, the market is divided into competent cells, expression vectors, instruments, kits and reagents, and protein expression services. The market is categorized into academic and research institutes, CROS and CDMOS, pharmaceutical/biotechnology companies, and other end-users based on the end user. Based on the application area, the market is categorized into research and diagnostics, and therapeutics. Based on the type of operation, the market is categorized into In-house and outsourced operations.
Based on the type of protein expression system, the market is divided into algal, cell-free, insect, mammalian, prokaryotic, and yeast. Among these, prokaryotic expression systems (particularly Escherichia coli) typically drive and hold the largest share of the protein expression market. his is due to their simplicity, cost-effectiveness, high yield, and rapid production rates. Prokaryotic systems are widely used in research and industrial applications to produce recombinant proteins. However, as the demand for more complex proteins grows, other systems like mammalian and yeast expression systems are also gaining significance for their ability to produce proteins with proper post-translational modifications. The ease of scaling up production in prokaryotic systems enables industrial-level protein manufacturing, making them ideal for large-scale applications like enzyme production, research, and biopharmaceuticals.
Based on the protein expression-related offerings, the market is divided into competent cells, expression vectors, instruments, kits and reagents, and protein expression services. Among these, kits and reagents dominate the protein expression market. This is because bio-experiments typically require a large volume of reagents for various steps in the protein production process. Reagents are crucial for every stage of protein expression, including cell preparation, vector transformation, and protein isolation. The high demand for these essential components, combined with their repeated use in experiments, makes them the largest revenue-generating segment in the protein expression market. Additionally, the growing need for reagents in both research and industrial applications further drives their dominance in the market.
North America, particularly the United States, is home to a highly developed biotechnology and pharmaceutical sector. Leading companies and research institutions in these fields are driving demand for protein expression technologies for drug development, biologics, and biosimilars. The region benefits from substantial investment in R&D from both government bodies and private organizations.
This funding supports innovations in protein expression systems, enhancing productivity and fostering new therapeutic applications. The rising incidence of chronic diseases, such as cancer, diabetes, and autoimmune disorders, in North America creates a high demand for protein-based therapeutics like monoclonal antibodies and vaccines, fueling the protein expression market.
