aPossible complementary binding sites of probes, bsites are denoted by the middle nucleotide of the complementary RNA region; cdeduced binding site for probe by comparison with DNA induced RNase H cleavage results; dnucleotides in capital letter (G, U, D) are 2′-O-methyl-RNA nucleotides, lower case letters (c, g, u, d) are LNA nucleotides, D and d are 2,6 – diaminopurine (2′-O-methyl type or LNA, respectively); ebinding was considered strong (S) when the integrated intensities were ≥1/3 of the strongest intensity. Hybridization condition: buffer 1, 37 °C; fΔG°37 calculated as modified probe/RNA duplex67,68, in parenthesis, the site of binding for which calculation was done; g(s) – strong RNase H cleavage, (w) – weak RNase H cleavage.
