Covalent antibody display--an in vitro antibody-DNA library selection system
7 Jan 2005
Abstract excerpt
The endonuclease P2A initiates the DNA replication of the bacteriophage P2 by making a covalent bond with its own phosphate backbone. This enzyme has now been exploited as a new in vitro display tool for antibody fragments. We have constructed genetic fusions of P2A with single-chain antibodies (scFvs). Linear DNA of these fusion proteins were processed in an in vitro coupled transcription-translation mixture of...
