1. A kit comprising:

  • a probe molecule for use in determining the presence of an RNA target in a sample, the probe comprising complementary first and second base regions that form a hybrid containing at least one 2′

    -O-alkyl ribonucleotide, wherein the probe forms a stable complex with the RNA target but not with a non-targeted nucleic acid under nucleic acid assay conditions, such that the RNA target can be detected, and wherein the complex comprises a single-stranded form of the probe; and

    a solid support for immobilizing the RNA target so that unbound nucleic acids and other components of the sample can be removed from the RNA target.
