Meeting Notes

Tic-Tac-Toe

Basic Idea

  • Use a chemical signal to induce electric output
  • Use E. coli as detector, Shewie as indicator
  • Use E. coli to produce lactate, needed for e- production in Shewie

Logistics of Game

Person v. Person

  • Example game:
  1. Player 1 adds chemical
  2. Computer tracks electric output and displays move on screen
  3. Player 2 adds chemical
  4. Computer tracks electric output and displays move on screen
  5. Repeat
  • One chemical detection needed

Person v. Computer

  • Example game:
  1. Player 1 adds chemical
  2. Computer tracks electric output and displays move on screen
  3. Computer chooses its move and lights up the well that it decides to move to
  4. Bacteria respond in a certain way
  5. Repeat
  • One chemical detection and one light detection needed

Person v. Bacteria

  • Most complex, based off of DNA paper (See [http://www.ncbi.nlm.nih.gov/pubmed/12923549?dopt=Abstract here])
  • Applying ideas from DNA paper to bacteria
  • Create 8 strains of different antibiotic resistances
  • More feasible in E. coli than in Shewie

Lab

  • picked colonies
  • rehydrated MR-1 shewie strain



Tuesday: June 17, 2008

  • GFP/OD Measurement (results)
  • Make glycerol stocks
  • Miniprep vectors (protocol)
  • Make competent Shewie
    • Chemically competent (protocol) - actually used Zymo protocol which didn't work for Shewie and I don't think for E. coli
    • Electrocompetent (protocol) - actually used earlier protocol w/o sorbitol
  • Pour Cm plates
  • Transform Shewie with pACYC Duet and GFP vectors

  • transform into E. coli TOP10 cells
  • Make chemically and electrocompetent Shewie MR-1
  • Transform electrocompetent Shewie MR-1 and E. coli
    • P3, P4, P5, A1 in shewie
    • P3, P4, A1 in E. coli (TOP10)


Results

  • Results for Tuesday's (6/17) transformations
    • Results for Electrocompetent cells (first procedure no sorbitol)
      • P4 (pACYC) worked for both Shewie and E. coli; E. coli had a much higher density of colonies
      • None of the other plasmids worked for either Shewie or E. coli cells grew (likely due to low concentrations of cells)
    • Results for Chemically competent cells (w/ Zymo procedure)
      • No Shewie (5) or E. coli (2) cells grew


Thursday: June 19, 2008

Results from Electroporated Shewie and E. coli plates

  • Shewie
    • P3 J23151 (Kan) colonies grew and expressed GFP; colonies may have a pinkish tint; unexpected b/c origin of replication
    • P4 pACYC-Duet (Cm) colonies grew
    • P5 pSB3K3 (Kan) no growth, possibly due to the very small volume of DNA added
    • A1 (Cm) a few colonies grew
  • TOP10
    • P3 J23151 (Kan) - colonies grew
    • P4 pACYC-Duet (Cm) - a little growth
    • A1 (Cm) - colonies grew

Results TOP10 transformations w/ registry parts

  • P4 lawn
  • P5 no growth?
  • P6 no growth?
  • P7 many small colonies
  • P8 many small colonies
  • P9 many small colonies
  • P10 many small colonies

Transformed Chemically Competent Cells from Wed 6/18

Restreaking electroporated E. coli plates

Some plates were overgrown (lawns/colonies too dense), so they were replated

  • P4 pACYC-Duet (Cm) restreaked from lawn onto 1000x dilution chloramphenicol plate)
  • P7 pSB1A2 one big and one small colony onto 2 ampicillin plates
  • P8 BBa_J04450 one big and one small colony onto 2 ampicillin plates
  • P9 BBa_J04430 one big and one small colony onto 2 ampicillin plates
  • P10 BBa_I715038 one big and one small colony onto 2 ampicillin plates

Some plates didn't have any visible colonies

Transforming TOP 10 with the light sensor biobrick

We attempted to transform TOP 10 E. coli with the light sensor biobrick (to make P11). No colonies were visible the next morning. This is perhaps because the DNA turned pink after being punched out of the notebook.


Friday: June 20, 2008

Results from Thursday 6/19 Transformations

  • Shewie - no growth
  • E. coli
    • P3 lawn
    • P4 lawn
    • P5 no growth
    • P6 no growth

[http://openwetware.org/wiki/IGEM:Harvard/2008/Lab_Notebooks/Meeting_notes#Notes_from_meeting Meeting with Orianna Bretschger]

Transformed S1 via Electroporation

We used the electroporation protocol as noted in [http://openwetware.org/wiki/IGEM:Harvard/2008/Lab_Notebooks/GenProtocols#For_electrocompetent_cells General Protocols] with the following volumes of vector added:

  • P1 (J23113 low) - 2uL
  • P2 (J23150 med) - 2uL
  • P3 (J23151 high) - 2uL
  • P12 (pET Duet-1) - 5uL
  • P13 (pCDF Duet) - 1uL
  • P14 (pCOLA Duet) - 1uL

Put on the following plates at 30 degrees C over the weekend:

  • P1 (J23113 low) - Kan
  • P2 (J23150 med) - Kan
  • P3 (J23151 high) - Kan
  • P12 (pET Duet-1) - Amp
  • P13 (pCDF Duet) - Sm
  • P14 (pCOLA Duet) - Kan

Transformation of plasmids 11 and 15-20

Chemically competent E. coli DH5a were transformed with plasmids 15-20. Additionally, p11 was repeated.

  • We noticed that after punching out the holes from the notebook, the DNA usually turned purple. The DNA that remained yellow turned purple after adding EB buffer. The protocol in the notebook recommends heating the EB buffer before use, but we did not do this. Instead, we incubated the DNA and EB buffer for 20 minutes at 42 °C (instead of at room temperature).
  • Additionally, due to time constraints, we only incubated the DNA and bacteria in SOC medium for 1 hour.
