Would that be five colonies from the same strain?
In that case: what's the difference between the colonies? Age? Size?...?
In my hands colony PCR "always" works, - if the colonies are fresh. - Old
plates: just forget it!
If it's two of five different strains that do work, then the differences in
physiology also can contribute to the problem. Try testing different initial
denaturing temps; 95 C - 97 C for 5-8 min are what I have played with. Then
use the program you have developed. Good luck.
