ABSTRACT:
The invention relates to bis-protein-DNA conjugates. A protein having a specific ligand binding activity is covalently linked to each end of a derivatized DNA molecule. These bis-protein-DNA conjugates can be used for immunoassays, PCR assays and measuring distances between proteins at up to 3.4 A resolution. The invention also relates to methods of synthesizing these bis-protein-DNA conjugates. Synthesis of the conjugates entails derivatizing the 5' or 3' end of a DNA oligonucleotide and covalently linking that DNA to a protein. The DNA can be conjugated to the proteins, including antibodies or Fab' fragments, using disulfide bond linkage.
