I would imagine there is some risk of that, but I haven't seen that happen in my experiments. I carried out a negative control using just SLiCE extract with competent cells (No insert DNA), and didn't get any colonies on amp plates. Also the colonies I sequenced from my tests were all correct, no pKD46 carryover. It might be that DNAse breaks all the DNA from the SLiCE cells. Normally when you do a plasmid prep, you add EDTA to prevent this, but no EDTA was added here. I'm not positive why, but empirically, I can say that it does not seem to be an issue.

Is there any worry that the amp resistant pKD46 plasmid will be extracted into the SLiCE lysate, in which case this plasmid will carry through to the final transformation? To me it would seem you can't use it to make amp resistant vectors..or maybe I'm missing something. Thanks for the clarification.RC--
