Abstract

To discriminate among miRNA length variants, we synthesized conformationally restricted or unrestricted oligonucleotides containing a cyclohexyl phosphate residue. These oligonucleotides formed duplexes with length-matched complementary miRNAs more tightly than with length variants. The use of one of these modified oligodeoxynucleotides as a reverse transcription primer enabled a novel RT-PCR that can discriminate among miRNA length variants.
