That is right Duncan, thank you for the answer, I will now go ahead with the
primers. I have a side question that you might have an opinion on!
I am going to attempt to do quantitative PCR with degenerate primers, I can
make the primers so that they should amplify all the genes I want, but again
the primers end up being 28 bp long with 8 bases (in the middle) having
degenerate composition (R,K and Y). Do you think it is possible to get these
primers working in a semi quantitative experiment?
