ABSTRACT
Two highly fluorescent compounds, viz. 6-(6-isobutyrylamino-1,3-dioxo-1 H,3H-benzo[de]isoquinolin-2-yl)-hexanoic acid and 6-(6-dimethylamino-1,3-dioxo-1 H,3H-benzo[de]isoqu-inolin-2-yl)-hexanoic acid have been synthesized, characterized, and attached to 12-mer oligodeoxyribonucleotides at their 5'-end using suitable linker molecule. These labeled oligodeoxyribonucleotides have shown appreciable fluorescence even at 0.0019 microM concentrations. Thermal denaturation studies have shown comparatively higher Tm values when oligodeoxyribonucleotides are labeled. These labeled oligodeoxyribonucleotides have been purified on RP-HPLC utilizing their hydrophobicity and on polyacrylamide gel because of their easy detection due to fluorescence.
