Cresol Red is another option. Just a quick warning for a problem we
encountered, which is that some of these dyes fluoresce. This is not
normally a problem, but can completely trash a sequencing reaction if
dye manages to get into the DNA template. There may be issues with
real time PCR detection as well.
