Explaining multiple peaks in qPCR melt curve analysis
Jan 20, 2014 · Melt curve analysis is frequently used as a tool for assessing qPCR amplicon length with intercalating dye qPCR assays. Here, we explain how melt curves are produced, examine the assumptions being used, and describe some additional methods that can be used to further analyze melt curve results.

About melt curve analysis - Thermo Fisher Scientific
Use melt curve analysis to determine the melting temperature (Tm) of the amplification products of a PCR that used intercalating dyes. Melting temperature (Tm) is the temperature at which 50% of the DNA is double-stranded and 50% is dissociated into single-stranded DNA.
2.2 Melt curve analysis A melt curve analysis allows the identification of a qPCR product’s melting point. This information is useful as a proxy for establishing qPCR product spec - ificity. For a melt curve analysis to be carried out, an additional thermocycling step is added at the end of the qPCR cycling program. During this step, the
Melting Curve Analysis - an overview | ScienceDirect Topics
Melting curve analysis (MCA) can be used to determine the specificity of the amplicons through the relationship between fluorescence dye intensity and the state of the reagent temperature. CPCR was combined with MCA to further determine the specificity of the CPCR amplicons [142].
What is High Resolution Melting (HRM)? - Bio-Rad
High resolution melt analysis (HRM analysis) is the quantitative analysis of the melt curves of product DNA fragments following PCR amplification. HRM can be considered the next-generation application of amplicon melting analysis.
Standard DNA melt curve analysis is a post-PCR analysis method based on a biophysical measurement of the amplified DNA. Historically, it has been used for various applications, most commonly to detect primer-dimers or other nonspecific by-products of PCR. A melt curve is generated by slowly denaturing (melting) the DNA sample
