Abstract

There is disclosed an oligonucleotide strand or duplex-targeting protein conjugate, a linking group to link an oligonucleotide to a targeting protein, and a method for producing targeting protein conjugates containing oligonucleotide strands or duplexes. A suitable linker is a bifunctional phosphoramidite ester that binds to both the targeting protein and the oligonucleotide strand or duplex. The invention can be used for delivering chemotherapeutic agents to target sites based upon the specificity of the targeting protein and to deliver specific oligonucleotide sequences to a target site to hybridize and inhibit the expression of complementary sequences within the target cell genome.
