Outline of Final Research Achievements |
Novel pyrene and perylene derivatives bearing a silly functional group were synthesized and incorporated into oligoDNA . The silylated pyrene and perylene derivatives possess enhanced fluorescence signal may be due to the characteristic sigma-pai interaction brought about by the silly group. The obtained oligoDNA baring a silylated pyrene at its 5'-terminus has a partial self-complementary sequence and, the fore, forms dumbbell shaped higher structure. In a buffer solution, the oligoDNA exhibited a faint fluorescence signal while it stays alone. On the other hand, the signal of the modified DNA showed a marked recovery (10 to 40 times) under the presence of the complementary oligonucleotide. In an appropriate conditions the modified DNA gave fluorescence signal under the presence of one-base mismatched complements in same extent as that while it stays alone. Thus, the modified DNA discriminated one-base mismatched complements with showing a fluorescence signal.
