Techniques are provided for generating an array-specific range of Tm values to be used for calling a sample in a given array positive or negative for a target nucleic acid sequence. A sample well in an array is provided with a control sample containing a control nucleic acid sequence. The control sample is amplified by thermal cycling the sample well. A Tm value for the control sample is identified and compared to an expected Tm value for the control nucleic acid sequence to calculate a relationship between the identified control Tm value and the expected control Tm value. By applying this relationship to an expected Tm value for a target nucleic acid sequence, an array-specific range of Tm values for the target nucleic acid sequence is generated and can be used for calling an experimental sample in the same array positive or negative for the target nucleic acid sequence.

System and method for identifying analytes in assay using normalized Tm values

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.
