Standard antibody phage-display panning uses purified proteins, antigen-transfected cells, or tumor cell lines as target structure to generate specific antibodies. Here, we describe a method for the selection of specific antibodies by phage panning against routine formalin-fixed paraffin-embedded (FFPE) tissue biopsies immobilized on glass slides. Selected antibody fragments recognize disease-associated antigens in its native conformation, suitable for the development of targeted diagnostic and therapeutic agents.
