The transformations from Sunday still have a bit of background from the vector but look much more promising than the past few attempts. Just to be certain, we set up another PCR screen and ran the products on a gel. Between all of the PCR screens we have run over the past week, it looks like we finally have all of the parts that we need to begin testing our mutants. We cultured the colonies that looked good and will have them sequenced to make sure that they are the correct parts.
Today we miniprepped the cultured constructs, nanodropped them, and sent them off for sequencing.
Did some more testing of our mutant PCR protocol. Tested various reaction conditions on R0010: perhaps using more template DNA will improve results, or running the PCR multiple times in succession.

Re-ran PCRs from yesterday to create second-round mutants, using 1/100th dilution of PCR product.
This product was then used to create a third round of mutants.
Mutants from yesterday were PCR prepped. Ran a diagnostic gel, got large, smeary, thick bands. All three were digested with EcoRI and SpeI, and the E0240-I13453-B0034-(Repressor) constructs were digested with EcoRI and XbaI.
