Abstract From the Canadian patent

conjugate probes are prepared in a one step process by incubating a macromolecule and a labeling group with a conjugating agent. The conjugating agent is capable of bonding virtually any labeling group to a macromolecule. Conjugate probes have been shown to have a high degree of specificity and exhibit a strong signal with minimal background.
