Abstract: Methods, sample vessels, and instruments are provided for melting curve analysis. A sample is amplified by thermal cycling the sample well between at least an annealing temperature and a denaturation temperature through n cycles, where each cycle includes an in-cycle denaturation step. Fluorescent data is collected during the in-cycle denaturation step of n cycles where n is at least two. Then a composite melting curve is generated using the fluorescent data collected during the denaturation step of each of the n cycles, and the sample is called using the composite melting curve, where the call is a positive or a negative call.
