Results:

May 25/2010

(in the lab:JV, HB, AV)

Objective: Transform the following ligated parts:

pLacI-sRBS (single cut from May 18,2010)

pLacI-sRBS (double cut from May 18,2010)

pLacI-sRBS-lumazine synthase-dt (from May 18, 2010)

Method:
Used Competent Cell Transformation to prepare plasmid DNA.
Results:
No colonies grew. No colonies on positive control plate. Something amiss here.
NOTE (June 1/2010; AS): Likely that the problem here was the method used to heat shock the cells. Cells were heat shocked in a heat plate, with incomplete contact of the heating surface, causing inefficient transfer of heat to cells for shock and movement of DNA into competent cells.

Conclusion: To be concluded....

Objective: Transform DH5α cells with plasmids containing ligation products from May 25/2010.
Method: Transform, using the competent cell transformation protocol, the ligation products with the most intense banding from each of the following ligation reactions:

mms6 + dT (B6 + A6)

xylE + dT (B4 + C4)

Incubate at 37^oC overnight.
Results:
No colonies grew, even on positive control plate.

May 31/2010

Objective: Transform part BBa_J33204 (Ribosomal Binding Site + xylE gene) into DH5α cells.
Method:
Obtained part BBa_J33204 from 2010 iGEM Spring Distribution Kit Plate 1, well 7P.
Transformed using competent cell transformation protocol, along with negative control (milliQ H₂O water) and positive control (pUC19 plasmid). Plated 100µL and 50µL on separate pre-warmed LB agar plates containing 100µg/mL ampicillin.
Added 250µL of SOC media and incubated for 90 minutes at 37^o.
Results:
Obtained the following number of colonies on each plate:

BBa_J33204 50µL - 13 colonies

BBa_J33204 100µL - 18 colonies

pUC19 - 9 colonies

Other lab activities:

Inoculated 5mL of LB liquid broth (Amp⁺ with cells containing Bba_J33204 picked from colony off transformation plate and incubated at 37^oC with shaking overnight.

AV quantified each pDNA stock in the working plasmids box by measuring the A₂₆₀ of a 1:100 dilution of the pDNA samples in a UV cuvette. Results are posted on the working plasmids page.

May 31/2010 - Evening

Objective: Transform recent ligation reactions that didn't work the first time around.
Method: Use competent cell transformation protocol to transform the following ligation products:

pLacI + sRBS

pLacI + sRBS-Lum-dT (times 2)

mms6 (B6) + dT

mms6 (A6) + dT

xylE (C4) + dT

xylE (B4) + dT

Plated all cells; spun down media so cells were pelleted and removed 200uL of cell-free media. Re-suspended pelleted cells in remaining media, and plated onto ampicillin plates.
Results:
No growth on plates EXCEPT:

Positive control (pUC19) - 9 colonies

mms6 (B6) + dT - 1 colonies
