Benchmarking Codon Optimization Strategies for Recombinant Antibody Expression

Many tools for codon optimization follow a rules-based approach, such that individual codons are optimized in isolation. While useful, this approach ignores the higher-order effects that are produced by codon combinations. It is therefore likely that rules-based codon optimization fails to meet the full potential output for any given gene. Here, we set out to test whether Twist’s LLM-driven codon optimization approach, which is able account for combinatorial codon effects, is capable of outperforming legacy rules-based and machine learning approaches across a panel of 32 antibody constructs.
