New vectors for peptide display on the surface of filamentous bacteriophage

We have modified the genome of the filamentous bacteriophage fd and also constructed a number of new vectors for the purpose of displaying peptides on the surface of the virion. These vectors facilitate the directional cloning of DNA encoding a peptide of interest at or near the N terminus of the major coat protein, the product of the bacteriophage gene VIII, and the construction of hybrid capsids in which the modified coat protein is interspersed with wild-type coat protein subunits.
