FAQ: When I run my sample in a gel after digesting with BseYI, the DNA doesn’t seem to migrate correctly. Is there a reason for that?

Yes. BseYI can remain bound to the DNA substrate after digestion altering the migration rate of the DNA during electrophoresis. To disrupt this binding, SDS to a final concentration of 0.5% can be added to the loading buffer prior to loading the sample in a gel. Alternatively, the DNA can be purified prior to electrophoresis.
