Abstract
The present invention relates to a double-stranded probe intended for the fluorescent detection of at least one single-stranded or double-stranded target nucleic acid, comprising: —a first strand of formula X1-(L1)a-S1-S′1-(L′1)b-Y1 intended for the detection of a first strand of the target nucleic acid which comprises a sequence of formula T′1-T1; —a second strand of formula X2-(L2)c-S2-S′2-(L′2)d-Y2 intended for the detection of a second strand of the target nucleic acid, if present, the second strand of the target nucleic acid comprising a sequence of formula T′2-T2; wherein two of X1, X2, Y1, and Y2 represent a fluorescent donor, while the two others represent a fluorescent acceptor, and X1 and Y2 can not both represent a fluorescent donor.
