July 1, 2008

Nathan Phillips, Andrew

Made 500 mL of LB agar + amp and 500 mL of Liquid LB

July 2, 2008

Nathan Puhl, Alix, Sebastian, Munima, Roxanne, Christa

Transformed [http://partsregistry.org/wiki/index.php?title=Part:BBa_J24679 BBa_J24679] (RBS + LacI), [http://partsregistry.org/wiki/index.php?title=Part:BBa_P0440 BBa_P0440] (RBS+TetR+T10+T12), leftover DNA from Double T (June 26, 2008), and 1 uL of pSB1A7 plasmid (June 18, 2008).

Protocol changes: 

  -3 uL of DNA
  -spin down 200 uL of cells and resuspend in 100 uL of LB; plate on LB + amp


July 3, 2008

Nathan Puhl, Munima, Christa, Alix, Roxanne, Sebastian

Checked transformation plates. Only the positive control (pSB1A7) had colonies (~1500) indicating that there is nothing wrong with the transformation protocol or cells so we must be having problems with the DNA extraction from the filter paper. Next week we will attempt various changes to the protocol to extract more DNA.


July 8, 2008

Munima, Christa, Nathan Puhl

Made 500mL of LB semi-solid media and poured 24 plates. Stored in the iGEM 4 C fridge

Nathan Puhl, Alix

Flourescent Reporter

Transformation from BioBricks LacI (BBA_J24679), TetR (BBa_P0440) and DT (BBa_B0015).

Protocol: 

  -punched out 2 spots of filter paper
  -15uL TE, for 30 min. @ 50 C
  -centrifuge 3 min. @ 15000 g
  -freeze 5 min. in -20 C freezer
  -heat shock 1 min. in 42 C water bath
  -centrifuge 3 min.
  -2 uL of plasmid into 25 uL DH5alpha
  -leave on ice for 30 min. 
     -(Left remaining DT, TetR, LacI to sit overnight at room temp. testing for better DNA recovery)
  -put in 42 C water bath for 45 sec.
  -chill on ice for 2 min.
  -add 1 mL of SOC broth
  -incubate cells @ 37 C, 225 rpm for 60 min.
  -spin down 400 uL cells (1 min. 16000xG), remove 300 uL
  -resuspend
  -plate, incubate at 37 C overnight

Subcultured 3 biobricks (for flourescent reporter) glycerol stocked from last year into 5 mL liquid LB + Amp. 

  -RFP Sub. (BBa_I13507)
  -pLACI (BBa_R0011)
  -pSTRONG (BBa_J23119)

July 14, 2008

Munima, Nathan Puhl, Alix, Andrew

Ran gel electrophoresis on "comp RP1616 + pSB1A7" cells, LacI, TetR and DT (from July 8/08). No DNA bands were observed.


July 15, 2008

Nathan Puhl, Andrew, Alix

Objective: Working on fluorescent reporter system; trying transformation from BioBricks again. Using: LacI (BBa_J24679) and DT (BBa_B0015)

Protocol - "Transformation - F00 v.1" (Glinko Bioworks): 

1. Get DNA from filter paper.
2. Place punch directly in 25 uL DH5alpha cells.
3. Leave on ice for 30 mins.
4. 45 second heat shock in 42 C water bath.
5. Chill on ice for 2 minutes.
6. Add 500 uL SOC broth.
7. Incubate at 37 C for 1 hour.
8. Spin down all cells.
9. Remove 400 uL.
10. Resuspend and plate on LB + Amp. Allow to incubate at 37 C overnight.


July 16, 2008

Andrew, Alix

Objective: Assess transformation success 

- observed growth on LacI and DT plates
- grew up cells with LB + Amp
- put into shaker incubator at 37 C overnight

July 17, 2008

Nathan Puhl, Alix, Munima, Christa

Objective: Assess transformation success and isolate a single colony for subculture 

 - streaked colonies onto Brent's LB + Amp plates because there was too much growth on the LacI/DT plates

Munima, Christa

Made 500mL of LB + amp semi-solid media and poured 25 plates. Stored in the iGEM 4 C fridge


July 21, 2008

Nathan Puhl

Subcultured single colony of re-streaked transformants in LB + amp and shaker incubated overnight at 37 C


July 22, 2008

Nathan Puhl, Andrew

Plasma prepped BBa_J24679 (LacI) and BBa_B0015 (DT) from transformed DH5-alpha

Transformed DH5-alpha with BBa_P0440 (TetR), BBa_I714062 (GTPTT), and BBa_J31007 (TetA) as per the protocol from July 15, 2008
