Sanger Sequencing: SAP Exo I cleaning of PCR products

We use Shrimp Alkaline Phosphatase from Amersham (E70092Z)
and Exonuclease I from New England Biolabs (MO293S).

1. Make up a master mix and dispense 30 µl into each well of an 8-strip tube.
2. Add 2.5 µl to each well of a plate of PCR products.
3. Seal the plate and place on the PCR machine.
