ABSTRACT:
Unitary hybridization probes having stem-and-loop structures, wherein the stem portion of the structure comprises a pair of interactive arms that are substantially prevented from interacting with target polynucleotides. One arm of the invented parallel-stem hybridization probe has a backbone polarity opposite that of the target-complementary loop sequence of the probe. Rather than interacting in an antiparallel fashion, the arms of parallel-stem hybridization probes interact in a parallel fashion. The arms of the invented dual inversion probes interact in a conventional antiparallel fashion, but have backbone polarities opposite that of the target-complementary loop portion of the probe. Arm portions of the inversion probes do not substantially contribute to sequence-dependent stabilization of probe:target hybrids. Incorporating inversion linkages into the structures of these probes dramatically simplifies the process of designing stem-and-loop hybridization probes.
