Abstract: A system (1000) comprising first and second excitation sources (101a, 101b) with respective excitation wavelengths for exciting first second and third dyes in a sample (110) and further comprising a detector (115), first and second emission spectral elements (121a, 121b) for transmitting respective first and second emission wavelengths as well as a processor (130) for automatically operating the elements of the system. The first dye comprises a first absorption spectrum comprising a first maximum absorption wavelength and the second dye comprises a second absorption spectrum comprising a second maximum absorption wavelength that is equal to or substantially equal to the first maximum absorption wavelength. The second dye comprises a second emission spectrum comprising a second maximum emission wavelength and the third dye comprises a third emission spectrum comprising a third maximum emission wavelength that is equal to or substantially equal to the second maximum emission wavelength.

Abstract: Energy transfer dye pairs including a donor dye covalently attached to an acceptor dye through a linker, uses of the energy transfer dye pairs, for example, in conjugates of an energy transfer dye pair covalently attached to a quencher and an analyte (e.g., an oligonucleotide), for biological applications including, for example, amplification assays such as quantitative polymerase chain reaction (qPCR) and digital PCR (dPCR).
