Abstract
The invention is directed to virus-like particles (VLPs) of an RNA bacteriophage that (a) comprises a coat polypeptide of said phage modified by insertion of a heterologous peptide that is displayed on said VLP and (b) encapsidates said bacteriophage mRNA as well as populations of these VLPs, and their uses. The invention is further directed to VLPs that encapsidate heterologous substances, as well as populations of these VLPs and their uses.
Claims2
A library of virus-like particles (VLPs) comprising a plurality of MS2 VLPs, wherein each particle of said library comprises a single chain dimer coat polypeptide having a random heterologous peptide inserted in the A-B loop of the downstream subunit of said coat polypeptide, wherein said random heterologous peptide is displayed on said VLP, wherein said random heterologous peptide is encoded by a polynucleotide that has 6, 8, or 10 copies of a NNY sequence, where N is adenine (A), Cytosine (C), guanine (G) or Thymine (T) and Y is cytosine (C) or thymine (T).
