Cloning of N-CPPs into pSB1C3

Transformation results

From 6/9 transformations

Good colony yields on both plates, 1 and 2*.

Colony PCR

4 colonies picked from each plate for verification by colony PCR.

  • 1, 2, 3, 4, 5*, 6*, 7*, 8*
  • PC: pSB1C3.RFP
PCR tubes
dH2O 16.22
DreamTaq buffer 2
dNTP, 10 mM 0.4
Fwd primer (VF2) 0.4
Rev primer (VR) 0.4
Cell suspension 0.5
DreamTaq pol. 0.08
  20 μl

Standard colony PCR settings

  • Elongation time: 0:45

Gel verification

Colony PCR gel verification of pSB1C3.N-CPPs
3 μl λ; 6 μl sample.
λ = GeneRuler 50 bp DNA ladder.

1.5 % agarose, 90 V.

Expected bands

  • pSB1C3.Tra10: 389 bp
  • pSB1C3.TAT: 359 bp
  • pSB1C3.LMWP: 368 bp

Results
Relevant bands in clones 3, 4, 6, 7 & 8. Slightly different in size, which could indicate presence of all three N-CPPs. All clones selected for sequencing.

ON cultures

For plasmid prep

  • pSB1C3.N-CPP: pC.NCPP 3, 4, 6*, 7* and 8*
    • 5 ml LB + Cm 25
    • 37 °C, 200 rpm ON

  50 μl
  • Incubation: 37 °C, 3 h
  • Inactivation: 80 °C, 20 min

Gel verification

Gel verification of N-CPP digestions.3 μl λ; 5 μl sample.
λ = GeneRuler 50 bp DNA ladder.

1.5 % agarose, 90 V

Expected bands

  • Tra10: 182 bp
  • TAT: 91 bp
  • LMWP: 94 bp

Results
Very irregular band sizes in the "lower" region, making no sense. Sizes not at all corresponding to what was expected.
Higher up very regular bands. This is even more puzzling, since different primer pairs were used for each PCR reaction. Although concentration of plasmid should be too low, the bands seen may be undigested and digested N-CPP plasmid. A too large plasmid concentration may in turn be the cause of the unspecific bands seen lower down in the gel.

Transfer of m-yCCS into pEX

ON cultures

Set ON cultures of pEX.yCCS for plasmid prep and glycerol stocks. From 3/9 colonies.

  • pEX.yCCS 5 and 8
    • 5 ml LB + Amp 100
    • 37 °C, 200 rpm ON
  • pEX.yCCS 5 and 8
    • 5 ml LB + Amp 100
    • 30 °C
