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.
本发明涉及强制插入探针(FIT-探针),包括至少一个核苷类似物,该核苷类似物包括至少一个荧光人工碱基,直接结合到一个修饰糖基的碳上,所述修饰糖基是一个
碳酸糖或一种
氨基酸核酸(
AANA)。因此,该核苷类似物被插入到DNA或RNA中,代替一个单个的天然碱基。
