Segmental Analysis

Product Type Insight

The reagents segment dominates the global market and is projected to exhibit a CAGR of 12.34% over the forecast period. A reagent is a substance used (in detecting or measuring a component, preparing a product, or developing photographs) due to its chemical or biological activity. In December 2021, Sino Biological Inc. launched a panel of research reagents for the Omicron variant (B.1.1.529) of the SARS-CoV-2 virus, which quickly raised concerns worldwide because of the high number of mutations it carried, especially the 30-plus mutations on the spike protein. Thus, the growing number of launches of reagents and the continuous use of these products are expected to expedite segment growth over the forecast period.

The instruments used in protein assays are chromatographic, electrophoretic, and immunochemical devices. The increasing number of chronic diseases and drug developments are expected to boost the segment's growth. In October 2019, BioTek Instruments Inc. launched quantitative assay apps, which provide convenience and simplicity for researchers performing four commonly used detection-based applications: absorbance-based BCA, Bradford and Lowry protein assays, and fluorescence-based DNA assays. These easy-to-use apps are powered by Gen5 data analysis software. They are compatible with BioTek microplate readers with the relevant detection mode, including the popular Cytation and Synergy multi-mode readers.

Application Insight

The drug discovery and development segment is the largest revenue contributor to the market and is estimated to exhibit a CAGR of 11.12% throughout the forecast period. Proteins are the primary target of any drug discovery and development activity; therefore, protein analysis is paramount in drug discovery and development. Target identification and evaluation, efficacy and toxicity biomarkers from readily available biological fluids, and investigations into drug action or toxicity mechanisms are just a few of the prevalent applications of protein analysis in drug discovery. These applications, in turn, are anticipated to grow significantly due to numerous drug discovery projects launched by pharmaceutical companies worldwide.

The need for developing medication is predicted to rise in tandem with the rising worldwide burden of infectious and chronic diseases like cancer, influenza, HIV, tuberculosis, and others. This will probably spur protein identification and interpretation research and propel the market for protein assays. A survey conducted by the WHO from January 24, 2022, to February 6, 2022, stated that approximately 12,368 people tested positive for influenza viruses. Of these, 8,423 (68.1%) people were typed as influenza A and 3,945 (31.9%) people as influenza B. Furthermore, 171 (6.4%) were influenza A (H1N1), and 2,483 (93.6%) were influenza B (H3N2). The abovementioned factors are expected to boost segment growth during the forecast period.

End-User Insight

The pharmaceutical and biotechnology industries segment owns the highest market share and is estimated to exhibit a CAGR of 11.01% during the forecast period. The pharmaceutical and biotechnology industries continuously adopt protein assays to develop better drug uses for disease diagnosis, further accelerating the identification and validation of new therapeutic targets. The increasing product launches by key players and increasing research and development using protein assay methods for drug discovery and disease diagnosis are also expected to boost market growth.

In April 2022, Bio-Techne Corporation and Cygnus Technologies, part of Maravai LifeSciences, launched the Simple Plex HEK 293 HCP 3G assay for automated process impurity testing on the Ella immunoassay platform. The new Simple Plex HEK 293 HCP 3G assay provides consistent, accurate, and controlled assay conditions for host cell protein (HCP) detection. Therefore, the new product launches are anticipated to boost market growth in the biotechnology industry.

The hospitals and clinics segment is expected to have lucrative growth due to increasing cases of cancer, neurological disorders, diabetes, and other chronic diseases. Patients suffering from critically severe conditions prefer getting treated at hospitals with the support of experienced and well-trained healthcare professionals. Hence, hospitals and clinics are the primary care settings for diagnosing and treating medical conditions. The major aspects fueling market growth in this segment are the rising inpatient and outpatient visits in hospitals for diagnosis and better treatment facilities provided by hospitals and clinics, such as better reimbursement scenarios and early diagnosis and treatment, an increasing number of new hospitals and clinics for disease diagnosis and monitoring, and strategic initiatives adopted by the care setting.

Regional Analysis

North America Dominates the Global Market

North America is the most significant global protein assays market shareholder and is anticipated to exhibit a CAGR of 11.56% during the forecast period. The North American region is anticipated to hold a significant share of the protein assay market during the forecast period because of the presence of a large pharmaceutical market, huge investment in the drug development and discovery initiative by a few of the largest pharmaceutical companies located in the region, the high prevalence of chronic illnesses, and the presence of a solid healthcare infrastructure in the region. For instance, the research and development expenditure of Pfizer, Inc., which is headquartered in the United States, increased from USD 9,393 million in 2020 to USD 13,829 million as per the company's annual report.

In addition, the rise in the frequency of chronic diseases in the region is expected to boost the market studied. For instance, in April 2021, the Canadian Cancer Society data stated that cancer is Canada's leading cause of mortality, accounting for roughly one-third of all deaths. This is poised to increase the demand for testing, increasing protein assay growth in the region.
