Sequencing without PCR purification

Dear Joao!

If you use less than 10 pmole of each primer in your PCR, you can take 2 ul
of non-purified PCR-product to your sequencing reaction. We do that
routinely in our lab and it work fine. This is with BigDye-terminators. I
don't know how it works with BigDye-primers.
