title: Catalytic antibodies: hapten design strategies and screening methods.
abstract: Catalytic antibodies have emerged as powerful tools for the efficient and specific catalysis of a wide range of chemical transformations. Generating antibody catalysts that achieve enzymatic efficiency remains a challenging task, which has long been the source of great interest both in the design of more effective haptens for immunization and in the development of more direct and efficient screening methods for the selection of antibodies with desired catalytic capacities. In this review, we describe the development of different hapten design strategies, including a transition state analog (TSA) approach, 'bait-and-switch' catalysis, and reactive immunization. We also comment on recent developments in the screening process that allow for a more efficient identification of antibody catalysts.
