I have to agree with David that they are very annoying, however before
you completely forget about them I would recommend a quick perusal of
their primer design tips. A while back I posted a summary of as many
online primer design tips as I could find one bored afternoon, and
Alkami's collected guidelines were easily the most entertainingly
self-contradictory. There are too many gems to quote them all, but I
can't resist reposting their crystal clear opinions on GC clamps.
1 " Start and end primers with 1-2 purine bases "
2 " Try to avoid Gs and Cs at the 3' ends "
3 " The primer should be able to form "G/C" clamps "
If you're not confused enough, check out the rest of the tips at
Happy primer "designing",
John (no afils etc.)
P.S. Hi Dave, I see above that you've been upgraded to Your Eminence
now apparently - I really am beginning to lag behind on these
