The most sophisticated T m calculations take into account the exact sequence and base stacking parameters, not just the base composition (1,2,3). The equation used is: Tm = ΔH kcal ∘ C × Mol ΔS + R In ( [primer] / 2) − 273.15 ∘ C. Δ H is the enthalpy of base stacking interactions adjusted for helix initiation factors (3,4).
