Abstract

See full text

The present teachings provide methods, compositions, and kits for quantifying target polynucleotides. In some embodiments, a reverse stem-loop ligation probe is ligated to the 3′ end of a target polynucleotide, using a ligase that can ligate the 3′ end of RNA to the 5′ end of DNA using a DNA template, such as T4 DNA ligase. Following digestion to form an elongated target polynucleotide with a liberated end, a reverse transcription reaction can be performed, followed by a PCR. In some embodiments, the methods of the present teachings can discriminate between polymorphic polynucleotides that vary by as little as one nucleotide.
