Abstract

Disclosed are targeting constructs for targeting a target site, including a molecule or complex of interest. The targeting constructs comprise a polymer chain and a plurality of multi-specific molecules each of which includes an affinity moiety for binding with the polymer chain and a targeting ligand for binding with the target site. The polymer chain may be associated with a therapeutic or diagnostic agent and generally comprises a plurality of sites, wherein individual sites bind with a multi-specific molecule of the target construct. The present disclosure also relates to methods of preparing the targeting construct and to its use in therapeutic and diagnostic applications.
