10 sec annealing? 1sec if using capiliaries. 20 with tubes.
Also I use a standard mix in my RapidCycler.9no optics)
I beleive the increase is in Mg since the borosilicate adsorbs a lot of Mg.
Contact DNAamp for their mix. I have never raised the primer conc with my
machine using their stuff. I may change this now.

I will check out this.

Now more and more are using this technology does anyone know of a forum or a
