SUMMARY

The discussion focuses on calculating the melting temperature (Tm) of PCR products for RT-qPCR melting curve analysis. It emphasizes that while Tm for primers is calculated based on single-stranded DNA, the same principle applies to PCR products, which are double-stranded. Participants recommend using online calculators, such as the one from IDT (http://biotools.idtdna.com/analyzer/), that account for the length of the nucleic acid when determining Tm. Ultimately, the Tm for PCR products should be calculated as if they were single-stranded to ensure accurate results.

PREREQUISITES
  • Understanding of PCR (Polymerase Chain Reaction) fundamentals
  • Knowledge of melting temperature (Tm) calculations for nucleic acids
  • Familiarity with RT-qPCR (Real-Time Quantitative PCR) techniques
  • Experience using online bioinformatics tools for nucleic acid analysis
NEXT STEPS
  • Research the principles of Tm calculations for double-stranded versus single-stranded DNA
  • Explore the use of online tools for Tm calculation, specifically IDT's Tm calculator
  • Learn about the implications of Tm on RT-qPCR assay design
  • Investigate best practices for interpreting melting curve data in RT-qPCR
USEFUL FOR

Researchers, molecular biologists, and laboratory technicians involved in PCR and RT-qPCR experiments who need to accurately calculate Tm for effective assay design and analysis.

I know how to calculate Tm of a primer but what about of a PCR product?

I want to run the melting curve in RT-qPCR to test for the products and i want to know Tm of the products to be sure.


Thanks.

Why not use the same calculation as the Tm of a primer? A good calculator should takes into account the length of the nucleic acid. How do you calculate it now?

The difference between a primer and a PCR product is that the PCR product is a double stranded DNA while the primer is just a singel strand. So should i calculate Tm for the PCR product like as it is a single strand?
 
Although you calculate Tm with a single strand for primer, it is use to separate your double stranded DNA.

So for your PCR product calculate with the single stranded DNA sequence.
