Market Dynamics

Driver - Increasing Research Focus on Difficult-to-express Proteins, Including Membrane Proteins and Protein Toxin Variants

Researchers are increasingly exploring the use of cell-free protein expression systems (CFPS) to produce difficult protein classes, including membrane proteins and protein toxins, outside of living cells. A 2023 study aimed at enhancing the yield of a model membrane protein through cell-free expression (CFE) highlighted key challenges, such as aggregation of nascent chains and ribosome cotranslational membrane association. The study found that incorporating lipid membranes into the reaction enabled proper insertion of nascent chains and minimized aggregation, resulting in significantly improved protein yields.

Another study involving high-throughput cell-free screening of 61 eukaryotic membrane protein targets in lipidic mimetics, including detergents, liposomes, and nanodiscs, reported soluble expression of 57% of the membrane proteins in at least one format. Furthermore, a 2024 article, “Circumventing the Impossible: Cell-Free Synthesis of Protein Toxins,” demonstrated that the fast and efficient synthesis of protein toxins, typically difficult or impossible to express in living cells, is becoming feasible for medical and diagnostic applications with CFPS platforms. CFPS can be used to synthesize, functionally characterize, and even modify protein toxins for downstream applications. The CFPS is increasingly the preferred platform where cell-based systems fail, driving further investment and research into optimizing these systems for such hard targets.

Restraints - Intellectual Property Constraints and Regulatory Gaps as Key Restraints in the Global Market

Cell-free protein synthesis (CFPS) systems face notable intellectual property (IP) hurdles, as patents extend across extracts, energy systems, enzymes, and reaction methodologies. These protections restrict access to core technologies, particularly for academic researchers and smaller biotech companies. Common host or extract systems, such as E. coli–based CFPS extracts and wheat germ platforms, are often covered by overlapping patents, creating complex licensing requirements that drive up costs and limit commercialization opportunities for new CFPS applications. In addition to IP barriers, regulatory challenges further slow adoption.

Existing global regulatory frameworks for therapeutic proteins are primarily designed for cell-based biologics, leaving CFPS-specific standards undefined. This lack of clarity delays clinical trials and product approvals, raising perceived risks for pharmaceutical developers and discouraging investment in CFPS-based therapies. Recent initiatives in 2025, including collaborative IP-sharing models, open-source CFPS toolkits, and CEPI’s funding of LenioBio GmbH and Abera Bioscience, are beginning to ease these constraints. However, patent restrictions and regulatory uncertainties remain significant obstacles to large-scale industrial and clinical deployment of CFPS technologies.

Opportunity - Strategic Collaborations with CDMOs and Contract Research Laboratories Present a Significant Growth Opportunity

Strategic collaborations with contract development and manufacturing organizations (CDMOs) and contract research laboratories (CRLs) present significant growth opportunities for cell-free protein synthesis (CFPS) providers, enabling them to scale their technologies and enter new markets. By leveraging CFPS innovations alongside the operational expertise of CDMO/CRL partners, companies can accelerate product development, enable rapid deployment of cell-free protein synthesis for research, clinical, and commercial applications, and support high-throughput workflows.

This approach addresses the growing global demand for vaccines, biologics, and advanced diagnostics, while offering flexible, cost-effective solutions across the biopharmaceutical and diagnostics sectors.

In April 2025, Ginkgo Bioworks partnered with ARPA-H, Tritica Biosciences, USP, On Demand Pharmaceuticals, and Isolere Bio under the WHEAT program to develop decentralized production of biologics and small-molecule APIs using wheat germ CFPS systems. Similarly, in October 2024, LenioBio GmbH collaborated with global CDMO ReciBioPharm to expand its CEPI-funded project, demonstrating the speed and capacity of its ALiCE® platform to accelerate vaccine protein production, supporting CEPI’s 100 Days Mission and highlighting the scalability and strategic potential of CFPS technologies.
