Abstract
Recombinant antibody fragments binding with high affinity to their target can be obtained either from hybridomas or directly from antibody libraries on filamentous phage. These fragments are devoid of any activity other than antigen binding, and have to be processed and functionalized in order to be suitable for clinical applications. This article presents the authors’ view on the procedures and the features that are important for effective transformation of recombinant antibodies into useful immunotherapeutic agents. The topics presented include phage display methodologies, engineering of high-affinity binding, purification, and functionalization strategies of recombinant antibodies.
