Affinity Maturation

Affinity maturation can improve binding to the intended target, but it can also alter the antibody paratope (the antigen-binding surface) in ways that create patch-associated nonspecific interactions. These liabilities may then require re-engineering before a candidate can progress as a therapeutic lead.

Learn how site-directed mutagenesis improves antibody affinity, binding specificity, and performance for therapeutic and diagnostic applications.

Affinity maturation is a hallmark of the adaptive immune system that enables B cells to generate antibodies with increased specificity and binding strength against antigens. Through cycles of somatic hypermutation (SHM) and clonal selection within germinal centers, antibody affinities can improve by several orders of magnitude. Understanding the molecular and biophysical mechanisms of this process has been essential for therapeutic antibody development and rational vaccine design.
