The protein expression market size has grown rapidly in recent years. It will grow from $3.97 billion in 2025 to $4.49 billion in 2026 at a compound annual growth rate (CAGR) of 13.3%. The growth in the historic period can be attributed to expansion of biologics development programs, increasing demand for recombinant proteins, growth of academic protein research, availability of diverse expression host systems, rising use of contract research services.

The protein expression market size is expected to see rapid growth in the next few years. It will grow to $7.37 billion in 2030 at a compound annual growth rate (CAGR) of 13.2%. The growth in the forecast period can be attributed to increasing demand for therapeutic protein production, rising adoption of cell-free expression technologies, expansion of industrial enzyme applications, growing investment in synthetic biology, increasing focus on rapid protein production platforms. Major trends in the forecast period include increasing adoption of mammalian and cell-free expression systems, rising use of recombinant protein production, growing demand for scalable expression platforms, expansion of custom protein expression services, enhanced focus on expression yield optimization.

The increasing demand for biologics is expected to support the growth of the protein expression market in the coming years. Biologics are therapeutic products derived from living organisms or composed of components such as proteins, tissues, genes, cells, and blood-derived materials, and are designed to deliver highly targeted and effective treatments. Demand for biologics is rising as the prevalence of chronic and complex diseases continues to increase, creating a need for more personalized and advanced therapeutic options. Protein expression is essential in this context, as it enables the efficient production of therapeutic proteins required for the development and manufacturing of biologic drugs. For example, in January 2023, according to Cardinal Health Inc., a US-based healthcare company, as of January 2022, the United States had 33 biosimilar products approved by the FDA, with 21 available on the market. By 2023, the number of FDA-approved biosimilars increased to 40, with 25 commercially available. Therefore, the growing demand for biologics is contributing to the expansion of the protein expression market.

Rising government funding for research in the biopharmaceutical industry is expected to further drive the growth of the protein expression market going forward. Government funding in this area refers to financial support provided by public authorities to organizations and institutions engaged in the development of new drugs and therapies. Such funding supports the protein expression market by encouraging the development of innovative protein expression technologies and helping to lower the costs associated with protein production. For instance, in March 2024, according to the Food and Drug Administration, a US-based federal agency, cooperative agreements are set to provide up to three awards totaling $600,000 in fiscal year 2024 and up to five awards totaling $1,000,000 in fiscal year 2025. These funding initiatives represent the FDA’s ongoing efforts to gather data on antimicrobial use in animals. Therefore, increasing government funding for biopharmaceutical research is driving growth in the protein expression market.

Major companies operating in the protein expression market are placing greater emphasis on launching next-generation solutions, such as the Visium CytAssist Gene and Protein Expression Assay, to strengthen their market presence. Next-generation solutions involve the adoption of advanced technologies and methods designed to enhance the efficiency, precision, and speed of protein expression. For example, in May 2023, 10x Genomics Inc., a US-based biotechnology company, introduced the Visium CytAssist Gene and Protein Expression Assay, which enables researchers to analyze relative protein expression patterns within the human immune system. Using Visium’s morphology-first approach, hematoxylin and eosin staining can be performed prior to any chemical treatment of tissue sections. This approach allows three-dimensional spatial analysis on the same sample while enabling detailed examination of tissue morphology on the same slice used for in-depth spatial multiomic analysis. By employing a sequencing-based readout, Visium CytAssist Gene and Protein Expression supports the simultaneous capture of protein expression and whole-transcriptome gene expression alongside histological analysis within a single experiment from a single tissue section.

Major companies operating in the protein expression market are Agilent Technologies Inc., Bio-Rad Laboratories Inc., Thermo Fisher Scientific Inc., New England Biolabs Inc., Promega Corporation, Qiagen NV, Takara Bio Inc., Merck KGaA, GenScript Biotech Corporation, Sigma-Aldrich Corporation, Lucigen Corporation, Lonza Group Ltd., Viva Biotech Holdings, ARTES Biotechnology GmbH, Addgene Inc., Profacgen, ProteoGenix Inc., Oxford Expression Technologies Ltd., Creative Biolabs Inc., Abnova Taiwan Corp., Accelagen Inc., Jena Bioscience GmbH.

North America was the largest region in the protein expression market in 2025. Western Europe was the second largest region in the protein expression market. The regions covered in the protein expression market report are Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, Middle East, Africa. The countries covered in the protein expression market report are Australia, Brazil, China, France, Germany, India, Indonesia, Japan, Taiwan, Russia, South Korea, UK, USA, Canada, Italy, Spain.

Tariffs are impacting the protein expression market by increasing costs of imported reagents, competent cells, expression vectors, bioreactors, and precision laboratory equipment. Pharmaceutical and biotechnology companies in North America and Europe are most affected due to reliance on imported biological materials, while Asia-Pacific faces pricing pressure on expression system exports. These tariffs are raising production costs and influencing outsourcing decisions. However, they are also driving local production of expression reagents, regional bioprocess manufacturing, and greater self-reliance in protein production workflows.
