Market Driver

Rising Demand for Novel and Bispecific Therapeutic Antibodies

The growth of the market is driven by increasing demand for novel therapeutic antibodies, including bispecific antibodies. These antibodies offer enhanced specificity and efficacy for treating complex diseases such as cancer and autoimmune disorders. 

Biopharmaceutical companies are increasingly investing in custom antibody development to meet the need for targeted therapies. Advances in antibody engineering and screening technologies support faster discovery and production of these antibodies.

• In July 2024, Bio-Rad Laboratories expanded its Pioneer Antibody Discovery Platform by introducing fast generation and screening of bispecific antibodies using its proprietary SpyLock Technology. This new service enables faster indentification of effective antibody combinations for development.

Market Challenge

Safety and Stability Challenges

A major challenge hindering the expansion of the custom antibody market is ensuring the safety and stability. Antibodies are susceptible to degradation and reduced efficacy if not properly stored or handled.  Additionally, they may trigger unintended immune responses in patients.

To mitigate these issues, companies are adopting advanced technologies to enhance antibodies robustness, along with rigorous testing to ensure safety and efficacy. Advanced formulation techniques and stabilizing agents are used to preserve antibody integrity during transport and storage. Regulatory compliance and stringent quality control procedures further support product reliability.

Market Trend

Advancements in Antibody Discovery Technologies

A notable trend in the market is the integration of antibody discovery platforms incorporating microfluidics, genetic engineering, and proprietary screening technologies. 

These platforms enable faster generation of fully human and bispecific antibodies from diverse B-cell populations. This reduce development time and increase the quality of antibody candidates. Consequently, therapeutic development is accelerated, enhancing the targeting of complex diseases.

• In March 2025, Biointron launched a high-throughput, fully humanized antibody discovery platform integrating AbDrop and Cyagen HUGO-Ab. This novel approach combines microfluidic technology for single B cell antibody discovery and fully human antibody mice using TurboKnockout ES technology, offering a safer and more efficient approach for fully human antibody discovery.
