The present teaching provides a fluorescent oligonucleotide probe having a high degree of design flexibility and wide applicability, as well as the use thereof. This is an oligonucleotide probe capable of forming a stem and loop, comprising at least one fluorophore located between adjacent nucleotides in the stem and is linked to a unit represented by Formula (1) and at least one quencher located at a site capable of pairing up with the at least one fluorophore located between the adjacent nucleotides in the stem and is linked to a unit represented by Formula (2). (In the formulae, X represents the fluorophore, Y represents the quencher, R1 represents an optionally substituted C2 or C3 alkylene chain, R2 represents an optionally substituted C0-2 alkylene chain, and Z represents a direct bond or linker.)
本发明提供了一种具有高度设计灵活性和广泛适用性的荧光寡核苷酸探针及其用途。这是一种能够形成茎和环的寡核苷酸探针,包括位于茎中相邻核苷酸之间并与式 (1) 所示单元相连的至少一个荧光团,以及位于能够与位于茎中相邻核苷酸之间的至少一个荧光团配对的位点并与式 (2) 所示单元相连的至少一个淬灭剂。(在式中,X 代表荧光团,Y 代表淬灭剂,R1 代表任选取代的 C2 或 C3 亚烷基链,R2 代表任选取代的 C0-2 亚烷基链,Z 代表直接键或连接剂)。
