Report Scope of the Polyclonal Antibodies Market

This is mainly attributed to the growing prevalence of infectious and chronic diseases such as cancer across the globe, increasing technological advancements in antibody-based drugs, and the rising R&D activities in the biopharmaceutical industry. Moreover, as compared to monoclonal antibodies, the manufacturing cost of polyclonal antibodies is less. Polyclonal antibodies (pAbs) are widely used in qualitative and quantitative biological analysis and various diagnostic testing. The COVID-19 pandemic significantly impacted the polyclonal antibody market. Various firms are working towards establishing pAbs-based in-house products that are used for treating individuals suffering from COVID-19. The rising acceptance of standard laboratory tests, such as western blot analysis, microarray assays, cell imaging, and immunohistochemical, is projected to propel polyclonal antibody market growth. For instance, GenScript, a U.S.-based biotechnology company, offers tailored pAbs that are appropriate for several assays type, such as CHiP, sandwich ELISA, Immunoprecipitation, Western Blot, IHC, IF, and Flow Cytometry. Additionally, according to an article published in April 2021, a human-derived antibody, SAB-185 developed by SAB Biotherapeutics, Inc., has been tested in a Phase 2/3 trial that is enrolled in non-hospitalized individuals with mild or moderate COVID-19 infections. Hence, these initiatives showcased the rise of demand for the pAbs during the pandemic period.

According to a report published by WHO in February 2022, approximately 10 million deaths were reported in the year 2020, among which, the most common cancers include lung, breast, rectum & colon, and prostate cancer. Furthermore, as per the article released by the American Cancer Society in January 2023, nearly 59,610 fresh leukemia cases (of all kinds) and 23,710 deaths caused due to leukemia (of all kinds) in the U.S. Polyclonal antibody treatment is widely used to treat various cancers including lymphoma, leukemia, solid tumor, and many more. For instance, in August 2021, the Cancer Prevention & Research Institute of Texas was funded with USD 250,000, for Antibody like Therapeutics which would Target Polyclonal T Cells to CMV-Positive Glioblastomas. Thus, the increasing prevalence of cancer is expected to create huge opportunities to propel the upsurge of the market.

According to an article published by the National Library of Medicine in May 2018, the rabbit model was adopted initially to study polyclonal antibody reactions and supported the immunogenicity associated with DNA immunization as an innovative immunization technique. Additionally, the rabbit model has been used significantly in the development of the HIV vaccine. Rabbits have a number of benefits over other small animals, such as mouse or rat, including, ease in inducing high-titer, high-affinity epitope-specific Abs that respond to nearly all kinds of antigens and minimal non-specific responses.

Additionally, government organizations around the world are increasingly recognizing the potential of the pAbs, and are taking initiatives to support its growth. These initiatives are aimed at promoting research and development, improving healthcare infrastructure, and providing funding for the development of new and innovative products. In September 2021, Regeneron Pharmaceuticals, Inc. announced their collaboration with the U.S. government, i.e., the Department of Defense (DOD) and the Department of Health and Human Services (HHS) for buying doses of REGEN-COV (casirivimab and imdevimab) antibody cocktail that is used in treating COVID infected patients in various hospitals.

Product Insights

In 2022, the secondary antibodies segment dominated the market with a market share of 57%. Secondary Abs bind to primary Abs that are raised against the target antigen and amplify the signal through various detection methods including ELISA, Western blotting, and Immunohistochemistry. In addition, secondary Abs are typically produced by immunizing host animals, such as rabbits, goats, or mice along with the immunoglobulin (Ig) of the same species as the primary antibody. Thus, this leads to the production of polyclonal secondary Abs that can recognize multiple epitopes on primary Abs, henceforth increasing the sensitivity and specificity of the assay.

The primary antibodies segment is expected to grow at the fastest CAGR of 6.48% during the forecast period. The increasing adoption of primary antibodies based (pAb-based) assays in clinical diagnostics, and rising demand for high-quality & diverse primary Abs are the factors contributing to the growth of the segment. Primary Abs are essential reagents for various clinical assays, including Western Blotting, ELISA, and Immunohistochemistry for the identification of disease biomarkers. Thus, as the demand for personalized medicine and biomarker-based diagnostics continues to grow, the primary antibody segment in the pAbs market is expected to grow further.

Application Insights

The diagnostics segment dominates the market for polyclonal antibodies with a share of 60% in 2022 and the same is anticipated to have the highest CAGR rate of 5.63% from 2023-2032. pAbs are considered to be an ideal reagent in hemagglutination reactions and diagnostics assay due to their capability to identify the epitopes of targeted molecules. Moreover, pAbs are relatively inexpensive to produce as compared to mAbs, as they can be produced by immunizing animals such as rabbits, goats, or mice, with the target antigen that would stimulate a polyclonal antibody response. In addition, the polyclonal antibody used in applications such as ELISA, Western Blot, and many others, are less likely to produce false negatives due to their ability to recognize multiple epitopes on the targeted antigen.

Biomedical research is projected to show significant growth during 2023-2032. This growth is due to their versatile nature, easy producibility, diverse range of binding specificities, and the ability to detect a wide range of biomolecules. In addition, as per the article published in January 2023 by ScienceDaily, scientists have developed a machine learning approach using AI technology to accelerate the production of new highly specific antibody drugs against diseases such as cancer, rheumatoid arthritis, and COVID-19. Additionally, in June 2021, Rapid Novor designed the first-of-its-kind sequencing technology, namely, REpAb, used for identifying sequences in pAbs utilized during drug discovery processes. Such technological advancements are expected to increase the demand for biomedical research during the forecast period.

Source Insights

The rabbit segment dominated the market in 2022 with a market share of 51% due to rapid immune response against small molecules, haptens, and post-translational modifications. Moreover, rabbit Abs have better affinity and specificity as compared to other animals. Rabbit-sourced antibodies (Abs) are highly specific Abs with a binding capability to various proteins in the picomolar range. Abs sourced from rabbits are highly particular, and showcase an improved immunologic response, thus facilitating better recognition of diseases during diagnosis. For instance, in February 2023, Roche announced the launch of two novel Abs (i.e., Rabbit Monoclonal Primary Antibody and the ATRX Rabbit Polyclonal Antibody) that would be used to identify the mutated gene in patients with brain cancer.

Mouse is expected to grow with the fastest CAGR of 8.05% during 2023-2032. Mice are widely available in research laboratories compared to other animals for the production of Abs that are manufactured using immunization protocols. Moreover, the growth factors for mouse-derived pAbs, include their high degree of homology with human proteins. Mice share a high degree of genetic and protein sequences similar to humans, making them one of the ideal hosts for generating pAbs that cross-react with human proteins.
