Abstract

A method for effecting helper phage rescue of a phagemid comprising a fusion polypeptide to form progeny bacteriophage wherein

(a) the helper phage encodes a viral coat protein comprising a protease sensitive cleavage site (b) the phagemid comprises a fusion polypeptide (c) the progeny phage are exposed to a protease capable of cleaving the proteolytically cleavable site such that the cleavage of the protein derived from the helper phage impairs its ability to mediate infection and (d) the progeny are propagated by infection. The helper phage has the protease sensitive site within p3 coat protein and is the filamentous bacteriophage M13, fd or a related species.
