Abstract

Claims (10)

1. A nucleic acid carrier comprising a first and a second oligonucleotide:

wherein a central portion of each of the first and second oligonucleotides is complementary to each other, forming a double-stranded region, wherein the double-stranded region is from about 25 to about 35 bases in length;

wherein the two terminal portions of the first oligonucleotide are not complementary to the two terminal portions of the second oligonucleotide, forming four single-stranded arms; and

an antibody, conjugated to at least one single-stranded arm of the four single-stranded arms.

2. The nucleic acid carrier of claim 1 , wherein the antibody is a Fab, F(ab′) 2 , scFv, tandem scFv, a BiTE, single domain (sdAb) antibody, diabody, single chain diabody, minibody, fusion protein, or scFv-Fc.
