ABSTRACT:
Targeting protein-diagnostic/therapeutic agent conjugates joined by stabilized Schiff base linkages are disclosed. Schiff base linkage of targeting protein and agent is accomplished without exposure of the targeting protein to harsh oxidizing or reducing conditions. The cleavable, heterobifunctional linkers that are described provide certain advantages relating to in vivo administration of targeting protein conjugates, including controlled release of active agent at a target site.
