1. An adapter-directed display system for displaying an exogenous polypeptide on the outer surface of a phage particle, comprising:

  • (a) an expression vector comprising a coding sequence that encodes the exogenous polypeptide fused in-frame to a first adapter sequence, wherein the vector is devoid of outer-surface sequences encoding functional outer-surface proteins of the phage particle;

    (b) a helper vector comprising outer-surface sequences encoding outer-surface proteins necessary for packaging the phage particle, wherein at least one of the outer-surface proteins is fused in-frame to a second adapter,said first and second adapters acting, when the polypeptide is produced in a suitable host cell, to cause the display of the polypeptide via pairwise interaction between the first and second adapters.
