The Benefits of Cell-Free Protein Synthesis in Protein Production

The field of protein production is seeing widespread adoption of cell-free protein synthesis (CFPS), revolutionising the industry with its high-throughput and cost-effective capabilities. This innovative method has created new opportunities for synthesising proteins, especially those that are challenging to produce in living cells. But what makes CFPS so advantageous, and why is it the preferred choice for high-throughput screening and directed evolution?

What is Cell-Free Protein Synthesis?

Cell-free protein synthesis (CFPS) is a technology that enables the production of proteins without the need for living cells. This approach utilises cell extracts containing the essential machinery for protein synthesis, along with a special mix of salts, cofactors, and energy sources designed to enhance protein yield and extend reaction duration. CFPS offers a rapid, flexible, and high-throughput alternative to traditional cell-based methods and has become a vital tool in pharmaceuticals, research, and biotechnology.

How Does Cell-Free Protein Synthesis Work?

Cell-free protein synthesis involves extracting cellular machinery like ribosomes, tRNAs, and enzymes from cells and using them in a controlled environment to synthesise proteins. This process bypasses the complexities of cell culture, leading to faster and more efficient protein production. Cell-free protein synthesis can be customised to produce a wide variety of proteins, including those difficult to express in living cells. Isomerase’s E. coli CFPS platform allows for tailored solutions in producing diverse proteins, from simple enzymes to complex biotherapeutics, ensuring high quality and efficiency.

What are the Advantages of Cell-Free Protein Synthesis?

CFPS offers several advantages over traditional cell-based methods:cell-free-synthesis-pipetting

  • Rapid Production: CFPS can produce proteins much faster than in vivo methods by bypassing the need for cell growth and division. Proteins can be produced in as little as three hours.

  • High-Throughput: The open nature of CFPS allows for high-throughput screening and production, which is beneficial for drug development and other applications. Hundreds of proteins can be synthesised simultaneously.

  • Cost-Effective: CFPS eliminates the need for traditional cell-based protein synthesis, allowing proteins to be synthesised and assayed on the same day. CFPS reactions can be scaled according to requirements.

  • Complex Protein Synthesis: CFPS is particularly useful for producing difficult-to-express proteins, such as membrane proteins or toxic proteins.

  • Open System: CFPS operates in an open system, allowing direct control and manipulation of the reaction conditions.

  • No Cell Dependence: It eliminates the need for living cells, avoiding complications related to cell viability and maintenance.

  • Focused Energy: The system directs all its energy towards synthesising the target protein, enhancing efficiency.

What Are the Applications of Cell-free Protein Synthesis in Research?

CFPS is a valuable tool for researchers studying protein function, structure, and interactions. It is rapid and cost-effective, allowing proteins to be produced for biochemical assays, structural biology studies, and functional analyses. In pharmaceutical development, CFPS can significantly speed up the drug discovery process. By enabling rapid prototyping and testing of therapeutic proteins, CFPS reduces the time and cost associated with drug development. Additionally, CFPS can produce proteins that are difficult to express in traditional systems, including toxic proteins, opening new avenues for developing novel therapeutics.
