We describe facile isolation of full-length IgG antibodies from combinatorial libraries expressed in E. coli. Full-length heavy and light chains are secreted into the periplasm, where they assemble into aglycosylated IgGs that are captured by an Fc-binding protein that is tethered to the inner membrane. After permeabilizing the outer membrane, spheroplast clones expressing so-called E-clonal antibodies, which specifically recognize fluorescently labeled antigen, are selected using flow cytometry. Screening of a library constructed from an immunized animal yielded several antibodies with nanomolar affinities toward the protective antigen of Bacillus anthracis.
