Wet Lab
From the transformations of yesterday, only 3/16 plates worked: the "classic method" LovTap-Term, its negative control (probably the Term plasmid religated), and one clone on the LacI-RBS-LovTap-Term!!! We suspect that the death cassette plasmid doesn't work correctly (since this hasn't been successful from the beginning), so next time we'll use other backbones for the ligation.

We did a colony PCR (with the iGEM primers) on 20 clones from the LovTap-Term, 5 from the negative control, and the one from the LacI-RBS-LovTap-Term, and ran the resulting fragments on an agarose gel to see whether the inserts were the expected ones. Result: only one of the 20 clones (LovTap-Term) was good.

We did a liquid culture of the right clone.

To redo the ligations for what didn't work, we did the "1,5-step PCR" again and the normal PCR with the 3 LacI-RBS we have.
