Global Protein A Resins Market to Reach USD 1.02 Billion by 2035, Driven by Biopharma Expansion and Monoclonal Antibody Demand

The global Protein A resins market is set for sustained growth, rising from USD 713.31 million in 2024 to USD 738.85 million in 2025, and projected to reach USD 1.02 billion by 2035, according to new industry data. The market will expand at a compound annual growth rate (CAGR) of 3.3% through the forecast period, underpinned by the accelerating production of monoclonal antibodies (mAbs) and biologic therapeutics.

Protein A resins have become indispensable tools in biopharmaceutical purification, serving as the backbone for antibody capture and downstream processing. These resins enable researchers to isolate target proteins in a single step, improving yield, purity, and process efficiency — vital advantages in drug discovery, vaccine research, and microbial infection studies.

Market Outlook: From Research Bench to Biomanufacturing

The growing adoption of recombinant Protein A resins—engineered for stability and high selectivity—continues to drive market expansion. In 2025, recombinant variants will command 74.4% of global market share, reflecting widespread use in both R&D and industrial antibody production.

“Protein A resin is to antibody purification what silicon is to microchips — it’s the foundation of the biologics revolution,” said Dr. Amanda Kerr, Senior Bioprocess Analyst at LifeScience Review. “With antibody-based therapies surging across oncology, autoimmune, and infectious disease portfolios, demand for high-efficiency purification media is accelerating globally.”
