What Is Covered Under Protein Expression Market?

Protein expression is a process in which proteins are synthesized, modified, regulated, and controlled in living organisms according to the host cell. Protein expression in the context of protein research can now also refer to the application of lab procedures necessary for protein production. The main product types for protein expression are reagents, competent cells, expression vectors, services, and instruments. A reagent is a substance or compound that is added to a system in order to produce a chemical reaction or to determine whether or not a reaction occurred. The various forms of protein expression include yeast expression, mammalian expression, algae expression, insect expression, bacterial expression, and cell-free expression that are used for therapeutic, industrial, and research applications. The different end users involve pharmaceutical and biotechnology companies, academic research, and contract research organizations.

What Is The Protein Expression Market Growth Forecast?

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.

What Are The Drivers Of The Protein Expression Market?

The rising demand for biologics is expected to propel the growth of the protein expression market going forward. Biologics are medicines derived from living organisms or containing components such as proteins, tissues, genes, cells, and blood derivatives, designed to provide highly targeted and effective treatment options. The demand for biologics is increasing because the growing prevalence of chronic and complex diseases is driving the need for more personalized and advanced therapeutic solutions. Protein expression plays a critical role in this landscape by enabling the efficient production of therapeutic proteins essential for developing and manufacturing biologic drugs. For instance, in January 2023, according to Cardinal Health Inc., a US-based healthcare company, as of January 2022, the US had 33 biosimilar products approved by the FDA, with 21 available on the market. By 2023, FDA-approved biosimilars had increased to 40, with 25 commercially available. Therefore, the rising demand for biologics is driving the growth of the protein expression industry. Increasing government funding for research in the biopharmaceutical industry is expected to propel the growth of the protein expression market going forward. Government funding for research in the biopharmaceutical industry refers to the financial support that governments provide to companies and institutions that are developing new drugs and therapies. It supports the protein expression market by supporting the development of new protein expression technologies and reducing the cost of protein production. For instance, in March 2024, according to the Food & Drug Administration, a US-based federal agency, the cooperative agreements will provide up to three awards totaling $600,000 in fiscal year (FY) 2024 and up to five awards totaling $1,000,000 in FY 2025. These funding opportunities represent the FDA’s latest effort to collect data on the use of antimicrobials in animals. Therefore, increasing government funding for research in the biopharmaceutical industry is driving the growth of the protein expression industry.

Global Protein Expression Market Trends and Insights

Major companies operating in the protein expression market are increasing their focus on introducing next-generation solutions, such as Visium CytAssist Gene and Protein Expression Assay, to maximize their revenues in the market. Next-generation solutions refer to the use of advanced technologies and techniques to improve the efficiency, accuracy, and speed of protein expression. For instance, in May 2023, 10x Genomics Inc., a US-based biotechnology company, launched the Visium CytAssist Gene and Protein Expression Assay to allow researchers to study the relative expression patterns of proteins within the human immune system. With Visium's unique morphology-first approach, H&E (Hematoxylin and Eosin) staining can be done before any chemical treatments are applied to the tissue section. This enables three-dimensional spatial analysis on the exact same sample while allowing researchers to investigate the morphology of their tissue on the same slice they use for deeper spatial multiomic inquiry. Utilizing a sequencing-based readout, Visium CytAssist Gene and Protein Expression enables the simultaneous collection of protein and entire transcriptome gene expression with histological analysis in a single experiment from a single tissue section.
