Context-dependent mutations predominate in an engineered high-affinity single chain antibody fragment

A mutational analysis of the femtomolar-affinity anti-fluorescein antibody 4M5.3, compared to its wild-type progenitor, 4-4-20, indicates both context-dependent and -independent mutations are responsible for the 1800-fold affinity improvement. 4M5.3 was engineered from 4-4-20 by directed evolution a...
