Affinity Maturation
Affinity maturation refers to the process of enhancing antibody affinity via in vitro experiments when the initial affinity is insufficient for downstream development. Conventional methods include constructing saturation mutagenesis libraries followed by high-throughput screening based on mammalian cell expression. We guarantee a more than fivefold improvement in the affinity of the delivered antibody.
Key Features
• AI-assisted antibody back-mutation design significantly improves efficiency and saves time.
• Unbiased CDR saturation mutagenesis combined with precise affinity data.
• Guaranteed affinity improvement—enhanced by several folds, reaching nanomolar levels or higher.
