Cloning of N-CPPs into pSB1C3 & Extraction of RBS BioBrick (BBa_B0030)

Transformations from 9/9 resulted in good colony yields on all plates. Chose "pSB1C3.N-CPP* 9/9" for colony PCR.

Colony PCR

Picked 12 N-CPP* clones (NC 1-12) and 4 RBS clones (RBS 1-4)

PCR tubes
dH2O 16.22
DreamTaq buffer 2
dNTPs, 10 mM 0.4
VF2 0.4
VR 0.4
DreamTaq pol. 0.08
Template DNA 0.5
  20 μl

PCR settings
Standard colony PCR protocol.

  • 1:00 elongation

Gel verification

Colony PCR gel verification of pSB1C3.N-CPP (NC) and pSB1A2.BBa_B0030 (RBS) clones.
50 bp λ = GeneRuler 50 bp DNA ladder; 1 kb λ = O'GeneRuler 1 kb DNA ladder

Also ran two samples for Mimmi (E & S)

1.5 % agarose, 90 V

Expected bands

  • N-Tra10: 389 bp
  • N-TAT: 359 bp
  • N-LMWP: 368 bp
  • RBS B0030: 253 bp

Results

  • N-CPPs: Potentially correct bands for clones 2, 3, 5, 8, 9, 10, 11 & 12
  • RBS B0030: Correct-sized bands for all four clones.

ON cultures

Set ON cultures for all relevant N-CPPs, for plasmid prep.

  • N-CPP 2, 3, 5, 8, 9, 10, 11, 12
    • 5 ml LB + 25 Cm
    • 37 °C, 220 rpm

Selected clone 4 of RBS 30. Both plasmid prep and glycerol stock.

  • RBS 30 4
    • 5 ml LB + 100 Amp
      • 37 °C, 220 rpm.
    • 3 ml LB + 100 Amp

Extraction of RBS BioBrick (BBa_B0034)

After studying the original RBS of our expression vector pEX, we decided that BBa_B0034 was a better candidate for our SOD/yCCS operon than BBa_B0030, as it better resembles the RBS of pEX, as well as minimizes the distance from the first gene in the operon.

Extracted BBa_B0034 (RBS 34), carried on pSB1A2, from iGEM plate 1, well 2M. Transformed into Top10.

  • Quick transformation
  • 1 μl DNA
  • Amp 100

Preparation of chemically competent Top10

Since I've previously experienced slight AmpR contamination in our latest batch of competent Top10, I streaked an LB agar plate with competent Top10 cells to isolate single clones.

Plate grown ON in 37 °C.
