When we do this we generally add 10-30 uCi of a ~3000 Ci/mmol dCTP,
without changing the other parameters or nucleotide mixes. The
resultant prob is generally hot enough for any application.
The molarity of the dCTP is low enough as to not greatly influence the
PCR reaction. You could make dCTP the limitting nucleotide in order
to get hotter PCR fragments but we have found that this really isn't
