The present invention provides a vector construct comprising the following components: (i) a sequence encoding a signal peptide which directs proteins into the Tat secretory pathway; and (ii) a sequence encoding a fluorophore fused to a sequence encoding a pVIII phage coat protein. Nucleic acid molecules comprising components (i) and (ii) are also provided, together with phage particles comprising such vectors or nucleic acid molecules and expressing a fluorophore-pVIII fusion protein on the surface. Methods for producing such fluorescent phage particles are also provided.

Vector construct

The present invention provides an alternative scaffold for peptides displayed on filamentous phages through novel fusion proteins primarily originating from pIX. Libraries of filamentous phages can be created from fusion proteins, and a phage display system comprising a phagemid and a helper phage is a part of the invention. An aspect of the invention is a kit containing a phage display system comprising a phagemid that contains a nucleic acid encoding the fusion protein of the invention and a helper phage.

Signal sequence-independent pIX phage display

The present invention provides an alternative scaffold for peptides displayed on filamentous phages through novel fusion proteins primarily originating from pVII. Libraries of filamentous phages can be created from fusion proteins, and a phage display system comprising a phagemid and a helper phage is a part of the invention. An aspect of the invention is a kit containing a phage display system comprising a phagemid and a helper phage that contains a nucleic acid encoding the fusion protein of the invention.
