Digestion with ScaI
we deactivate the digestion enzyme 20 minutes at 80°, the we added SAP for an hour at 37° and also this was deactivated for 20 minutes at 80°.It was also done an electrophoretic run to verify the result of this digestion: As you can see from the picture there is a unique band at about 6000 bp (Kapa Universal Ladder was used).
