    ABSTRACT: The covalent conjugation of oligonucleotides to antibody Fab' fragments was optimized by using oligonucleotides modified with a hexaethylene linker arm bearing three amino groups. One oligonucleotide was coupled to antibody of one specificity and a complementary oligonucleotide to antibody of a second specificity. The antibodies were then allowed to hybridize by base pairing of the complementary nucleotide sequences and the generation of bispecific antibody was analyzed on SDS-PAGE and confirmed using BIAcore analysis. The strategy of complementary oligonucleotide-linked bispecific molecules is not limited to antibodies but is applicable to linking any two molecules of different characteristics.
