Challenges: Diversity, Affinity, and Developability

Antibody library technology has become a cornerstone of therapeutic antibody discovery, enabling the rapid identification of candidates with high specificity and affinity. However, as the field advances into 2025, several persistent challenges remain—most notably in the areas of library diversity, affinity maturation, and developability of selected antibodies.

A primary challenge is achieving and maintaining sufficient diversity within antibody libraries. The theoretical diversity of antibody variable regions is immense, but practical limitations in library construction, transformation efficiency, and display systems (such as phage, yeast, or mammalian display) often restrict the actual diversity to 10⁹–10¹¹ unique clones. Companies like Abcam and Twist Bioscience are addressing this by leveraging high-throughput DNA synthesis and advanced cloning techniques to construct libraries with greater sequence variability and representation of rare antibody frameworks. These efforts are expected to further expand accessible diversity in the coming years, but the challenge of ensuring functional diversity—whereby the library contains antibodies with a broad range of binding specificities and biophysical properties—remains significant.

Affinity maturation is another critical hurdle. While initial library screens can yield binders to a target antigen, these often require further optimization to achieve the sub-nanomolar affinities needed for therapeutic use. Technologies such as error-prone PCR, chain shuffling, and site-directed mutagenesis are routinely employed to improve affinity, but these processes can be labor-intensive and may inadvertently reduce antibody stability or expression. Adimab, a leader in yeast-based antibody discovery, has developed proprietary platforms that integrate affinity maturation with developability screening, aiming to streamline this process and reduce attrition rates.

Developability—the likelihood that an antibody candidate can be manufactured at scale, remains stable, and is non-immunogenic—is increasingly recognized as a bottleneck. Many antibodies identified from libraries exhibit poor solubility, aggregation, or unfavorable post-translational modifications. To address this, companies such as Lonza and Sartorius are investing in predictive analytics and high-throughput biophysical screening to assess developability earlier in the discovery process. These approaches are expected to become more sophisticated with the integration of machine learning and AI-driven modeling by 2025 and beyond.

Looking forward, the antibody library technology sector is poised for further innovation, with a focus on expanding library diversity, integrating affinity maturation with developability assessment, and leveraging computational tools to predict and optimize antibody properties. These advances are anticipated to accelerate the path from discovery to clinic, but overcoming the intertwined challenges of diversity, affinity, and developability will remain a central focus for the industry in the near future.
