WEEK 1: 6/06-6/10/2011
  • Included a boot camp.
  • Different topics were discussed (i.e. biobricks, gene regulation, differences between eukaryotes and prokaryotes).
  • Boot camp also included a computer science component (focused on Clotho).
  • Miniprepes were done on previously transformed BFP2. After minipreps, the Nanodrop was used to quantify the DNA. Minipreps did not have high DNA concentration, but were run on a gel (to show presence of DNA). Most lanes appeared empty (bands of DNA were not visible).
  • Transformations of Pbad were conducted.
    • The following day, transformations appeared to be contaminated. They looked significantly different than usual, but were still were used to produce overnight cultures.
    • To ensure that E.coli was present gram staining was performed. Staining showed that no E.coli was present in the cultures. Nanodrop was used to quantify the DNA from the overnight cultures.
      • The results from the Miniprep/Nanodrop varied (some overnight cultures had a decent DNA concentration, others didn’t). Even though yields were not great the samples were run on a gel. However no bands were visible.
WEEK 2: 6/13-6/17/2011
  • Overnight cultures were made from the previous week’s transformations.
    • cultures didn’t grow properly (only UV plasmid).
  • An issue with the plates was discovered. All previous cultures were done on Ampicillian plates, and most were not growing well. We switched to a different antibiotic (Kanamycin) and all proceeding cultures grew well.
  • New Ampicillian plates were made.
  • A side project involved ligating GFP (Bba_J52625) and terminator (Bba_B0015) together for future use.
  • Transformations were completed (involved transforming several different biobrick parts).
    • Two seemed to look pinkish, especially towards the center of each colony.
    • Successful transformations were then used to produce more overnight cultures.
WEEK 3: 6/20-6/24/2011
  • Overnight cultures were made for the following: Bba_B0015.1, Bba_B0015.2, Bba_B0015.3, Bba_B0015.4, Bba_R0040.1, Bba_R0040.2, Bba_J52028.1, Bba_J52028.2, Bba_J52028.3,and Bba_J52028.4.
  • Nanodrop was also conducted. Chart below shows values from 6/23/2011.
Sample # ng/uL 260/280 260/230
Bba_E0240 2.70 3.54 0.01
Bba_E0430 1.5 -32.2 0.01

Bba_I13453.2 1.8 29.53 0.02
Bba_I13453.3 1.9 1.93 0.01
  • Ligation was also performed. I tried ligating BFP (Bba_K156010) with terminator (Bba_B0015.2.2). Transformation was done of this ligation later that day. The following morning the transformation plates did not have any colonies on them.
  • Minipreps were conducted on 6/23/2011’s overnight cultures and Nanodrop quantification was then performed. Results are shown below in the following chart:
