In recent years, cell free expression systems have emerged as a promising alternative for the conventional cell based protein manufacturing process. It is a well-known fact that traditional biomanufacturing is a complex process that requires living cells and specific conditions in order to maintain proper homeostasis for cell growth. Moreover, cell based biomanufacturing imposes inherent limitations on the effective production of biologics.

On the other hand, cell free protein expression systems are in-vitro platforms that harness the transcription and translation machinery of living cells, in the form of cell lysates, to synthesize various types of biologics, particularly proteins. A number of players have also developed kits for the cell free expression of enzymes, a class of proteins, It is worth highlighting that Enzymit, a bioproduction firm, utilizes cell free technology to synthesize cost-effective enzymes.

Overall, cell free protein expression systems offers several advantages over the traditional process, including the ability to produce a broad range of target molecules by altering components suited for their production, higher yield, shorter development times and low cost of production. Cell free protein expression is carried out using cell free system or commercially available cell free expression kits.

Cell-free protein expression systems have demonstrated to be capable of enabling the synthesis of several complex proteins, including toxic proteins, membrane proteins and other post translationally modified proteins, which have been found to be challenging to express using cell based systems. Given the growing demand for biologic products, cell free expression has become a key focus area for stakeholders in the biopharmaceutical industry.

We have considered the ongoing activity and existing trends in the cell free protein expression market, including enzymes. Further, we have also looked at the recent trends in the cell free expression of oligonucleotide synthesis and other biomolecules, as the cell free trend is catching up beyond protein expression. The global market for cell free protein expression is anticipated to witness growth at 6.9% CAGR during the forecast period, driven mainly by the rising demand for protein therapeutics and vaccines.

Cell Free Protein Expression Market: Key Insights

The "Cell Free Protein Expression Market: Industry Trends and Global Forecasts, till 2035" report features an extensive market research of the current market landscape of cell free protein expression kits and contract manufacturers / research organizations offering cell free protein expression service, cell free protein expression market size and likely future potential associated with the industry, during the forecast period. Key takeaways of the market analysis are briefly discussed below.

Need for Cell Free Protein Expression

Driven by several blockbuster products and a burgeoning pipeline, biologics (and consequently their manufacturing) have emerged as one of the key focus areas for stakeholders engaged in the pharmaceutical industry. However, biologic manufacturing is often fraught with several challenges, including inconsistencies related to quality of the final product, facility limitations, high attrition rate of pipeline candidates, prolonged development timelines, and regulatory / compliance-related issues. Therefore, biopharmaceutical firms are actively taking initiatives to identify approaches to overcome the existing challenges associated with biologic manufacturing.

Amongst several alternatives, the use of various types of cell free protein expression systems, including microbial cell free expression systems, mammalian cell free expression systems, plant-based cell free expression systems and other cell free expression systems, has emerged as a viable option for the synthesis of proteins. This can be attributed to the fact that cell free protein expression systems enable faster and economical synthesis of these complex molecules in shorter time.

Key Advantages of Cell Free Protein Expression

Cell free protein expression systems allow consistent manufacturing of products at varying scales of production (from very small (microliter) to very large (1000 L)), by using the same stockpile of reagents. Additionally, the absence of cell walls in cell free system helps in optimizing various steps of the overall biomanufacturing process by facilitating the addition / removal of enzymes and cofactors (which are continuously produced and degraded at varying rates by living cells), as well as enabling direct monitoring of the entire process. Further, cell free protein expression systems allow rapid manufacturing of time-sensitive products (such as the required therapies / vaccines during a pandemic) from the previously harvested active ribosomes and other necessary cellular machinery.

Cell Free Protein Expression Market Landscape

There are companies offering cell free protein expression kits or cell free protein expression services.
