Abstract: The invention relates to a kit for targeting of a diagnostic or therapeutic agent to a target site comprising: (a) a first conjugate comprising (i) a targeting moiety capable of binding selectively to the target site; and (ii) a first hybridization probe moiety comprising a PNA oligomer; and (b) a second conjugate comprising (i) a second hybridization probe moiety comprising a complementary PNA oligomer; and (ii) a diagnostic agent or a therapeutic agent moiety; wherein the length of the complementary PNA oligomer in the second hybridization probe moiety is not more than 14 bases. The invention further relates to methods for delivering a diagnostic or therapeutic agent to a target site in mammals, as well as methods for the diagnosis or treatment of medical conditions, such as e.g. cancer, in mammals.
