Week of 8/3/14 through 8/9/14
- During this week, the team realized that the contamination was coming from our stock of cells that was being kept in the -80C freezer. We have no idea how they became contaminated, seeing as continued to use the line of cells we froze for a week after we froze them, but before any contamination occurred. Nonetheless, one of our advisers has procured a new stock of top 10 E. coli cells for us to use.
- After unsuccessful runs of electrophoresis gels, we have run out of DNA to try to measure. So, we took some time out this week to streak, grow, and purify lines of our K1477014 and K1477030 parts on both pSB1C3 and pSB1AT3 backbones.
Week of 7/13/14 through 7/19/14
- This week we worked towards switching our part's backbone from pSB1AT3 to pSB1C3. We had some difficulty doing this. The first attempt was fruitless, but on our second attempt we had success and we now have a stock of our part on a chlor-resistant backbone.
- Unfortunately, We no longer have any stock of our original part. So, now we are again following the Biolabs Biobrick Assembly Manual to reconstruct our parts K1477014 and K1477030. Our first try yielded nothing.
- Our second run through of the protocol resulted in the in the growth of red colonies on chlor plates after electroportion of our part into Top 10 cells. However, we need white colonies to grow because this will point towards the rfp being repressed when the three parts come together. Red colonies are a sign that we did not have a successful assembly of our parts.
Week of 5/25/14 through 5/31/14
- We transformed Top 10 cells through electroporation with registry parts K112806 (Endolysin,) I732020 (LacZoperon Mutant,) J23102 (p-con) and I712074 (T7 promoter.)
- After streaking on plates, and leaving them in the incubator for a day, there was growth on all plates, showing that a successful transformation occured.
- Plates containing J23102 were red-another sign of success. Unfortunately, it looks like contamination has arisen as well, and is spreading on plates with I712074 and K112806 growth.
- The contamination persisted all week, but we were able to get plates with transformed parts that contained no contamination growth.
- We then ran a DNA purification protocol of J23102 and I732020 to get them ready for a biobrick assembly protocol.
