DARPA’s Vision: Reimagining Protein Manufacturing (RPM) for a Healthier Future


Proteins are essential molecules that play a vital role in all aspects of life, from cell signaling to metabolism to immunity. However, the current methods for manufacturing proteins are often inefficient, time-consuming, and expensive. Reimagining Protein Manufacturing (RPM) is a DARPA program that aims to develop new technologies to revolutionize the way proteins are made. RPM is focused on developing cell-free protein synthesis (CFPS) technologies that are more efficient, scalable, and cost-effective than traditional methods. In this article, we will delve into the intricacies of RPM, its objectives, and the potential it holds for revolutionizing the production of therapeutic proteins.

The Need for Transformation

Therapeutic proteins, including monoclonal antibodies, cytokines, clotting factors, and vaccines, are at the forefront of modern medicine. These proteins play a pivotal role in treating a wide range of diseases, from cancer to autoimmune disorders, and even in responding to biological threats. However, the traditional methods of manufacturing these proteins come with their own set of challenges.

Traditional Challenges in Protein Manufacturing

  1. Time-Consuming: Traditional manufacturing processes often involve the cultivation of living cells, which can take weeks or even months to produce therapeutic proteins.
  2. Complexity: The complexity of cell-based production and the need for precise post-translational modifications add layers of intricacy to the manufacturing process.
  3. Cost: The cost of producing therapeutic proteins can be prohibitively high, limiting access to these life-saving treatments.
  4. Scale-Up Issues: Scaling up production to meet the demands of a global market can be challenging, with scalability often constrained by the inherent limitations of cell-based systems.
  5. Security Concerns: Ensuring a secure supply chain for critical medical countermeasures is a significant concern, especially in times of national security.

DARPA’s RPM: A Paradigm Shift

The RPM program, initiated by DARPA, seeks to address these challenges head-on by reimagining how therapeutic proteins are manufactured. At its core, RPM envisions a future where protein production is transformed into a more efficient, accessible, and secure process.

RPM is focused on developing cell-free protein synthesis (CFPS) technologies that are more efficient, scalable, and cost-effective than traditional methods. CFPS is a process that uses purified components of a cell to synthesize proteins in a test tube. This approach has several advantages over traditional methods, including:

Key Objectives of RPM

  1. Distributed Production: RPM aims to shift from centralized, large-scale manufacturing to a more distributed model. This approach envisions on-demand production of therapeutic proteins, reducing reliance on a single source and enhancing supply chain resilience.
  2. Cell-Free Protein Synthesis (CFPS): Central to RPM is the exploration and advancement of Cell-Free Protein Synthesis (CFPS), a revolutionary technology that liberates protein synthesis from living cells. CFPS offers rapid, high-yield production with greater flexibility.
  3. Efficiency and Quality: RPM seeks to improve the efficiency and quality of therapeutic protein production, addressing bottlenecks in current manufacturing methods and reducing production timelines.
  4. Post-Translational Modifications: Overcoming the challenge of replicating post-translational modifications is a key focus area. RPM aims to enable the production of proteins that require specific modifications, expanding the scope of therapeutic applications.
  5. National Security: By enhancing the capacity to respond rapidly to biological threats, RPM aligns with national security objectives. The program aims to bolster our ability to provide medical countermeasures during emergencies.

Collaborative Endeavors

DARPA’s RPM is not a solitary endeavor. It thrives on collaboration, bringing together experts from diverse fields to tackle the complex challenges of protein manufacturing. The involvement of organizations like Ginkgo Bioworks, Imperial College London, Nature’s Toolbox, Inc., and prominent consultants underscores the multidisciplinary approach required for success.

Awards Recognizing Pioneers

In 2021, DARPA awarded $50 million in contracts to six research teams to develop new cell-free protein synthesis (CFPS) technologies. The teams are working on a variety of projects, including developing new methods for optimizing CFPS conditions, improving the stability of proteins produced by CFPS, and producing proteins that require post-translational modifications.

In 2022, DARPA announced that it is expanding the RPM program to include research on new applications for CFPS. The program is now focused on developing CFPS technologies for use in the production of proteins for medicine, food, and industrial applications.

In 2023, DARPA is expected to release a request for proposals (RFP) for the next phase of the RPM program. The RFP is expected to focus on developing CFPS technologies that are even more efficient, scalable, and cost-effective.

In July 2023, the Defense Advanced Research Projects Agency (DARPA) awarded Ginkgo Bioworks a groundbreaking 4-year contract worth up to $18 million. This prestigious award is a testament to Ginkgo’s leadership in the RPM project and their commitment to advancing CFPS technology. Here’s why this award is so significant:

  1. Innovative Leadership: Ginkgo Bioworks, a leading company in synthetic biology and genetic engineering, is spearheading the RPM project. Their expertise and dedication to engineering biology for global challenges make them a natural choice for this groundbreaking initiative. Ginkgo Bioworks will leverage its cutting-edge technologies, including its high-throughput, automated Foundry and proprietary genetic data Codebase. These assets, comprising over a billion proprietary gene sequences, provide a solid foundation for rapid prototyping, optimization, and development of proteins, enzymes, metabolic pathways, and even whole organisms under commercial-scale manufacturing conditions.
  2. Collaborative Efforts: Ginkgo is not alone in this endeavor. They lead a diverse team of experts, including representatives from Imperial College London, Nature’s Toolbox, Inc., and consultant Michael Feldhaus. This collaborative effort ensures a multidisciplinary approach to tackling complex challenges.
  3. Transformational Potential: The DARPA contract awarded to Ginkgo Bioworks signifies the immense potential of CFPS and the RPM project. It paves the way for a future where the rapid, local, and on-demand production of complex therapeutic proteins becomes a reality.

Here are some of the potential applications of CFPS technologies developed through the RPM program:

  • Production of vaccines and drugs: CFPS could be used to produce proteins that are used in vaccines and drugs. This could help to make these products more affordable and accessible.
  • Production of food products: CFPS could be used to produce proteins that are used in food products, such as meat substitutes and dairy products. This could help to address the growing demand for protein-rich foods.
  • Production of industrial products: CFPS could be used to produce proteins that are used in industrial products, such as cleaning products and cosmetics. This could help to make these products more sustainable and environmentally friendly.


The DARPA Reimagining Protein Manufacturing (RPM) program represents a bold step toward a future where therapeutic proteins are produced efficiently, affordably, and securely. As RPM continues to progress, it holds the promise of transforming healthcare, biotechnology, and national security by making life-saving treatments more accessible and responsive to emerging challenges. As scientists and researchers push the boundaries of what is possible, the RPM initiative offers a beacon of hope for a healthier and safer world.
