Have you tried using the plasmids for dye terminator sequencing?  We've
found that this is much more sensitive to the way the template is prepared
than Sequenase with dideoxy terminators.  On the other hand, we reliably get
450 instead of 250 b.p. of seqeunce, so a little more cost and effort is
worth it.

I would love to hear of a quicker, cheaper way to make reliably high quality
template for Taq cycle sequencing with dye terminaters.  Any suggestions?
