| Summary: | This study sought to develop a short DNA detection method using a deoxyuridine probe and polymerase chain reaction. The probe was hybridized to the target short DNA, which was then extended by DNA polymerase. The extended DNA was used for real-time PCR after the probe was removed by uracil DNA glycosylase. This method measured from 0.01 to 10 nM of a model short DNA sequence of 17 nucleotides. The method was then used to detect the nucleic acid medicine fomivirsen, as well as 21 phosphorothioate nucleotides, and to quantify 0.1–100 nM of fomivirsen. This method may be useful for detecting short DNA fragments, such as functional nucleotides. |
