This protocol describes a method for creation of a highly diverse and functional synthetic phage-displayed repertoire of fully human domain antibodies (dAbs). The repertoire is based on two human frameworks (one VH and one Vκ) that express well in bacteria and are frequently used in human antibodies. To achieve this, we first build dAb libraries, containing full synthetic diversity at key positions in the complementarity-determining regions (CDRs).

We have combined phage display and array screening for the rapid isolation of pairs of interacting polypeptides. Our strategy, named SAC (selection by avidity capture), is based on the avidity effect, the formation of highly stable complexes formed by multivalent interactions; in our case, between a receptor (multivalently displayed on phage) and a ligand (coexpressed as a multimeric fusion protein). Capture of the long-lived interaction complex allows the isolation of phage bearing cognate interaction pairs, as we demonstrate for a range of interactions, including Ab-antigen pairs and the rapamycin-dependent interaction of FKBP-12 and FRAP.
