Calculate the melting temperature (Tm) of oligonucleotides based on sequence, concentration, buffer, and salt conditions. Use the formula that includes or excludes magnesium effects on helix stability.
Tm Tool is a software that calculates and predicts the melting temperature of DNA, such as primers, probes, and oligos. It uses the nearest-neighbor method and adjusts for laboratory conditions and sequence concentrations.
The DNA Melting Temperature is a critical concept in molecular biology, representing the temperature at which half of the DNA strands are in the double-helix state and half are in the “melted” single-strand state.This temperature is crucial for designing PCR primers and understanding DNA stability. How to Use DNA Melting Temperature Calculator?
Estimate a suitable annealing temperature for PCR and qPCR products from PCR Biosystems. Select polymerase, modify primer concentration, input primer sequences, and use batch mode for multiple primers.
Calculate the melting temperature (Tm) of primers based on their sequence, concentration, and salt and Mg2+ conditions. Choose between basic or degenerated nucleotides, and see the formulas and examples.
LNA-enhanced oligonucleotides have different melting properties from DNA oligonucleotides. To use this melting temperature prediction (Tm) tool, just enter your sequence below and press "calculate". DNA nucleotides are entered as A, C, T or G, and LNA nucleotides are written +A, +C, +T or +G.

Fundamental Formulas for Melting Temperature (Tm) Calculation. Melting temperature (Tm) is the temperature at which 50% of the DNA duplex dissociates to single strands. Accurate Tm calculation is essential for PCR primer design, hybridization assays, and nucleic acid research. 1. Wallace Rule (Basic Approximation)
The annealing temperature for PCR is typically set between 55℃ to 60℃. The values of ΔH and ΔS are taken from the reference. By checking the box for “Multiple Sequences“, you can calculate the Tm of multiple primer sequences at once. References. Breslauer, K.J. et al. (1986) Proc. Natl. Acad. Sci. USA. 83: 3746-3750.

How to calculate the melting temperature of a primer? Use formulas or online tools to find a primer's melting temperature (Tm). A common formula is Wallace's rule: Tm = 2(A+T) + 4(G+C). A and T are the numbers of A and T in the primer. Online tools give more accurate Tm based on salt concentration and primer length.
