Affinity maturation of human botulinum neurotoxin antibodies by light chain shuffling via yeast mating

Abstract excerpt

Botulism is caused by the botulinum neurotoxins (BoNTs), the most poisonous substance known. Because of the high potency of BoNT, development of diagnostic and therapeutic antibodies for botulism requires antibodies of very high affinity. Here we report the use of yeast mating to affinity mature BoNT antibodies by light chain shuffling. A library of immunoglobulin light chains was generated in a yeast vector...
