title: Synthesis and property of DNA labeled with fluorescent acridone.
abstract: Triphosphate of a thymidine analogue bearing acridone was prepared from a modified thymidine nucleotide with a terminal amino group at C5 position and an acridone derivative as a new fluorecsent-tagged nucleotide. The acridone-tagged nucleotide was incorporated into DNA enzymatically during PCR using KOD Dash DNA polymerase. Further, we introduced the acridone derivative into an amino-modified DNA chemically by post-synthetic modification, and investigated their fluorescence properties and hybridization ability. The new fluorescent-labeled DNA bearing acridone will be useful as a DNA probe.
