The present invention is directed to kits for monitoring a nucleic acid during amplification. More particularly, the present invention relates to kits comprising a first oligonucleotide labeled with a first fluorophore, a second oligonucleotide labeled with a second fluorophore, and components for amplifying the locus, wherein the first and second fluorophores comprise a fluorescence resonance energy transfer pair. Hybridization of at least the first oligonucleotide to the amplified locus places the first and second fluorophores in a resonance energy transfer relationship.
