Nearest Neighbor Tm Approx
Approximate primer melting temperature with a salt-adjusted nearest-neighbor style formula.
Description
Approximate primer melting temperature with a salt-adjusted nearest-neighbor style formula.
Nearest Neighbor Tm Approx is a focused biology tool that approximate primer melting temperature with a salt-adjusted nearest-neighbor style formula. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use Nearest Neighbor Tm Approx
Use Nearest Neighbor Tm Approx when you need to approximate primer melting temperature with a salt-adjusted nearest-neighbor style formula. Enter Primer sequence and Sodium concentration using the definitions and units below so the result can be reproduced.
- Primer sequence
- A sequence, category, or text value.
- Sodium concentration
- A finite measured or assumed value, expressed in M.
How Nearest Neighbor Tm Approx calculates the result
The published tool contract uses this rule: Approximate primer melting temperature with a salt-adjusted nearest-neighbor style formula.
- Melting temperature
- The calculated melting temperature in °C.
Limitations of Nearest Neighbor Tm Approx
The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.
Alternative or Complementary measurements
Retain the original Primer sequence and Sodium concentration values and their units alongside the result. Salt-Adjusted Tm is useful when you instead need to estimate DNA melting temperature with a monovalent salt correction from GC fraction and sequence length. GC Rule Tm provides another view by helping you estimate DNA melting temperature with the GC rule for sequences longer than 13 bases.
