-KK Today we ran our digested CRO insert on the low melt gel, and under the UV light we saw the band we were looking for. Clarisse excised the band and we performed a ligation reaction according to the protocol and using the vector that we had already run on a low-melt gel last Thursday. After incubating for 30 minutes at room temperature, we performed a transformation into DH5alpha. The selectable marker of pLAT is ampicillin.

-KP We ran our low melt gel with our Cro insert. After 45 minutes, we put the gel under UV light and cut out the insert. We then performed a ligation of our vector and cro insert. After 30 min, we did a transformation and inserted our newly ligated plasmid into DH5alpha.

-KK When we dropped by today two of our plates (out of four) were contaminated. The two contaminated plates, we noticed, were the two plates that were old. The other two plates had a few colonies, but the was not a significantly greater number of colonies in our plasmid + insert + E.Coli plate than there were in our control plasmid + E.Coli plate. Kelton went ahead and streaked the few colonies we had to singles. We can PCR-verify if any of them have the plasmid. Meanwhile I am going to redo the transformation today. I will plate 4 plates: one 50 microL test, one 100 microL test, one 50 microL control, and one 100 microL control.

-KP Today we started out by getting photographed. We also watched the phage group’s presentations. It seems as if they have a good start to their project. We didn’t have too much time to do our own experiments, but we did set up an overnight to do mini-prep tomorrow, and we streaked out our plates of lambda phage.

-KK The three phage groups presented today. I realized how very quickly each of our groups has specialized to the point that I have to concentrate deeply to understand what seems to be second nature to members of the phage group. That’s good! It means each of our groups is moving along nicely. The objective of the phage project is to make a library of sizes - the biggest and smallest phage capsids possible using phages that have already been well characterized and approved for medicinal purposes. One group is working on selecting for the largest phage possible, one for the smallest, and another group is developing a method to purify both phages as they are made. Afterwards, we laid out singles of our three E.Coli strains with Lambda prophage incorporated into its genome. Tomorrow Kelton and I are going to go in and check on them after our Intro to Medicine class.

- Took plates from 5.15 out of incubation at around 4:00pm

5/17/13

- Determined that all LB plates from 5.8 had contamination

- Poured new LB plates

- Made x8 top agar

5/18/13

- Stacked up the LB plates made yesterday. No obvious sign of contamination seen.

- Threw away the 5.8 LB plates (the ones with contamination).
