Research Abstract

To improve the detection limit of the probe for 19F MR detection or imaging of target nucleic acids, new 19F labeling reagents were synthesized and introduced to the 5’ end of oligonucleotide probe having stem-loop structure. Results of the 19F NMR measurement in the presence of target DNA suggesting that the 19F labels having mono chiral structure have 5-fold large S/N ratio compared with racemic one, and the multi labeling is effective for improvement of detection limit. Furthermore, the probe capable of ratiometric detection of target DNA was successfully developed.
