description:
The epitope-specific scFv CM79 partially blocked (up to 18%) the binding to CPG2 by human antibodies from patients treated with A5B7-CPG2 antibody-enzyme conjugates. Single alanine substitution of residue R162 reduced binding of 11 patient sera by 19 to 62%, indicating this is a critical residue for human antibodies to CPG2 induced by CPG2 conjugate therapy.
