PCR Screening of L173 transformants

Transformation results (rbs-TetR in mRFP-LVA-tripart-pSB1A3)

Ligation L173

  • insert: D112 (ES) rbs-TetR
  • vector: D187 (EX) mRFP-LVA-tripart-pSB1A3
Sample positive control
pUC19 		negative control
no DNA 		ligation control
(without insert) 		L173 (3:1 ratio) L173 (4:1 ratio)
Number of colonies many 1 0 2 0

PCR Screening

PCR screening

PCR screening programm

  • elongation tim: 2 min
  • primers used: O18 & O19
  • positive PCR control: S158 (pSB3K3)
  • negative PCR control: no template
Well n° 1 2 3 4 5 6 7
Sample 1 kb
DNA ladder 		positive PCR
control 		negative PCR
control 		negative transformation
control clone 		L173.1 L173.2 100 bp
DNA ladder
Expected size 1894 bp
Measured size 1,2 kb 1,2 kb


Results: the clones are not correct.

Digestion

Digestion n° DNA substrat Digestion by
D112 MP106: S03879 (rbs-TetR) in pSB1A2 EcoRI & SpeI


  • 5 µL of DNA
  • 3 µL of 10X buffer n°2
  • 0,3 µL 100X BSA
  • 1 µL of EcoRI
  • 1 µL of SpeI
  • 19,7 µL of water


Incubation 2h30 at 37°C and then 20 min at 65°C.
Not purified yet. Put at -20°C.

Transformation results

L177 = d134 + d187 (pFlhB-mRFP LVA+)

L175 = d149 + d° (pFliL - ECFP LVA+)

L176 = d149 + d° (pFliL - ECFP LVA-)
