How to calculate primer annealing temperature? :idea: Please give the step and suitable formula (manual calculation)? :?: In my experiment DNA template will used and primer basepair between 18 to 25 basepair (Primer minimum size = 18 and Primer maximum size is 25). thanks for answer. :roll:

I think, pDRAW32 program can calculate it ;)
On synthesis report I has found formula for primers of 13-50bp long:
Tm = 100.5 + (41*(yG+zC)/(wA+xT+yG+zC)) - (820/(wA+xT+yG+zC)) + 16.6*log10[Na+]
The last part adjusts the Tm for changes in the salt conc.

Try ;)

A don't double your posts!

Cis or trans? That's what matters.
