There are a number of web-based tools available for predicting DNA melting curves and denaturation profiles of PCR products. Some examples include:
OligoCalc: This tool allows you to enter the sequence of a primer or probe and provides information on melting temperature, specificity, and primer-dimer formation.
PrimerQuest: This tool, developed by Integrated DNA Technologies (IDT), allows you to design primers and probes, and provides melting temperature predictions, specificity analysis, and potential primer-dimer formation.
Primer-BLAST: This tool, developed by NCBI, allows you to design primers and probes, and provides melting temperature predictions, specificity analysis, and potential primer-dimer formation.
Primer3Plus: This tool allows you to design primers and probes, and provides melting temperature predictions, specificity analysis, and potential primer-dimer formation.
Primer-Melting: A web-based tool that allows the prediction of melting temperatures for primers, primer-dimer formation, and specificity analysis.
PrimerMelter: A web-based tool for the prediction of melting temperatures for primers, primer-dimer formation, and specificity analysis.
It's important to note that the accuracy of these predictions can be affected by a number of factors, such as the accuracy of the sequence data, the experimental conditions, and the primer design. Therefore, it's important to experimentally validate your PCR products to ensure that they are of suitable quality for your downstream applications.
