SpletHello Cody, The melt curve is nothing but the minimum temperature at which your double stranded DNA becomes single stranded (melting). It is totally based on the nucliec acid … Splet13. sep. 2024 · The PCR melting curve of the standard product is shown in Figure 3. Through the analysis of the melting curve, it was found that the melting curve of the target gene showed a single peak, and the melting temperature was 85.31±1°C, indicating that the gene cpcB can be specifically amplified, indicating that the PCR method is specific.
SpletHigh resolution melting assays typically involve qPCR amplification followed by a melting curve collected using a fluorescent dye. Due to the sensitivity of high-resolution melting analysis, it is necessary to carefully consider PCR cycling conditions, template DNA quality, and melting curve parameters. SpletMelt 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 …
