The global cell-free protein expression market size was valued at USD 229.7 million in 2021 and is expected to expand at a compound annual growth rate (CAGR) of 8.48 % from 2022 to 2030. Cell-free protein expression i.e. cell-free protein synthesis is a technique that allows scientists to rapidly manufacture and express small quantities of functional proteins. Compared to in-vivo techniques based on tissue culture or bacterial cells, CFPE is significantly faster as it does not require extensive protein purification, cell culture, or gene transfection. Increasing research and development in genomics and proteomics, high prevalence of infectious diseases and cancer, and structural modification and shorter-expression time required in CFPE are major factors driving the growth of the market.
As the world continues to struggle with the current effects of COVID-19, scientists are using synthetic biology, and precise, cell-free systems to advance novel vaccines, diagnostic tools, and treatments. For instance, biologists at the University of Toronto extracted enzymes required for translation and transcription from Escherichia coli to develop a cell-free expression system that identifies the parts of the SARS-CoV-2 genome and activates a molecular shift to generate a reporter protein. This technique also eliminated the requirement to purify the RNA from the sample and replaced RT-PCR for additional rapid diagnostic testing. Such novel developments increased the adoption of CFPS in the diagnosis of COVID-19 and contributed to the CFPS market growth.
Cell-free protein expression (CFPE) is one of the widely used techniques in molecular biology. Proteins can be produced in a few hours using CFPE whereas, protein production using cells usually takes about a few days to weeks. So, in comparison with the traditional approaches, CPSE-based protein production can be time-saving from the initial synthesis to downstream applications. For instance, Promega’s, transcription and translation systems offer a time-saving substitute for eukaryotic in vitro transcription by coupling the procedure in a single tube format. Similarly, The human cell-free protein expression system aids in easy and simple in vitro translation and transcription. The single tube reaction of protein expression can be completed in one hour. This expression system allows high-yield expression and purification of functional protein.
Moreover, cell-free expression kits are helping in the faster expression of desired proteins in a short duration. For instance, the AccuRapid CFPE kit helps in the expression of a required protein in a reaction tube within 3 hours using the template DNA. Therefore, a reduction in the expression time is increasing the adoption of CFPE in the production of proteins by various industries can drive the CFPE market in the future.
Cell-free protein expression systems are evolving into a key platform for synthetic biology applications. Many synthetic biology tools are depended on cell-based systems, however, their constraints have led to the progress of cell-free protein expression and their applications in synthetic biology.
Furthermore, cell-free methods are being developed for biomanufacturing and prototyping. In prototyping applications, cell-free systems are utilized to optimize and test biosynthetic pathways before administration in the live cells and scale-up. For instance, the enzymatic pathways are constructed by a modular assembly of lysates containing enzymes produced by CFPS rather than living cells which reduces the time taken to build the pathways from months to a few days. This approach coupled with machine learning and automation can quicken the tests for combination metabolic pathways. Some of the commercially available strains and plasmids used for cell-free prototyping pathways include NEB Turbo and BL21 manufactured by New England Biolabs.
The expression systems segment held the highest share of the market in 2021. E. coli lysates is one of the most preferred lysates commercially due to their cost-effectiveness and higher protein yield. Moreover, E. coli-based systems used in recombinant technology are used for a wide range of biological therapeutics, involving insulin.
Wheat Germ Cell-free Protein Expression System is expected to expand at the fastest CAGR. The wheat germ system offers the maximum translation efficiency among the eukaryotic CFPE approaches and has an extreme success rate for the expression of soluble proteins of exceptional quality. In addition, this system is a choice of preference for numerous applications in protein research comprising options for protein labeling and the expression of proteins such as multiple protein complexes and membrane proteins.
The enzyme engineering segment dominated the market with a share of 34.97% in 2021. With the continuous growth of enzyme engineering, it has played an important role in biomanufacturing synthetic biology, and medicine. Lately, cell-free synthetic biology approaches for enzyme engineering have been used as an alternative strategy. This method has no constraint on the cell membrane and does not need to maintain cell viability, and each of the biosynthetic pathways is highly flexible.
Moreover, the high throughput production system is expected to register the fastest CAGR. The usage of CFPS for high-throughput enzyme screening has been proven to be a competent technique to discover improved enzyme variants and novel biocatalysts. The incorporation of cutting-edge high-throughput technologies allows the application of a Cell-free protein expression system for speedy prototyping to fast-track the screening procedure of enzymes with enhanced characteristics.
The transcription & translation systems segment captured the highest revenue share of the market in 2021. Coupled translation and transcription systems provide investigators with time-saving options for eukaryotic in vitro translation and transcription, by connecting these procedures in single tube format. Transcription and translation systems are used for numerous applications in low-to-high throughput functional proteome and genome analyses.
The pharmaceutical & biotechnological companies segment captured the highest revenue share of the market in 2021. The expansion of the current manufacturing capacities for biopharmaceuticals drives the demand for cell-free protein expression products.
