Web1.3 Melting temperature ( Tm) and GC content. Tm is the temperature at which half the primer strands are bound to the target. It depends on base composition and can be roughly estimated as. However, this equation neglects the dependence of Tm on strand concentration, salt concentration, and base sequence. Typical errors for this method … WebWelcome. The Tm Tool SM is a web-based application created to calculate and predict the melting temperature of DNA, specifically primers, probes, and small oligos. Predicting melting temperature (Tm) is a simple way to quantify the melting point of DNA. This tool calculates Tm with the nearest-neighbor method with adjustments for laboratory …
WebApr 2, 2015 · Science. qPCR assays using intercalating dyes, such as SYBR® Green dye, are an economical and effective tool for measuring gene expression. To interpret intercalating dye assays, users need to know how to analyze melt curves, and understand the benefits and limitations of melt curve analysis.
