The present invention relates to forced intercalation probes (FIT-probes) comprising at least one nucleoside analog which comprises at least a fluorescent artificial nucleobase directly bound to a carbon of a modified sugar moiety wherein said modified sugar moiety is a carba-sugar or an amino acid nucleic acid (AANA). Thereby the nucleoside analog is incorporated into DNA or RNA in the place of a single native base.

However, most previously reported dye–DNA conjugates showed only little if any difference between the fluorescence of the single and the doublestranded state. Here, we introduce a TO-containing acyclic nucleotide, which is coupled during automated oligonucleotidesynthesis and provides for the desired fluorescence-up properties. The study reveals the conjugation mode as the most important issue. We show
