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

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.

Construction of pFlhB-mRFP-LVA-tripart & pFliL-ECFP-LVA-tripart

Part icon regulatory.pngPart icon rbs.pngPart icon reporter.pngPart icon terminator.pngPart icon terminator.png

  • L183 = pFlhB - mRFP LVA+
  • L184 = pFliL - ECFP LVA+
  • L185 = pFliL - ECFP LVA-


Measurement of the concentration of the purified digestion

Protocol (it's same that for Miniprep)

Digestion Name Concentration (µg/mL) Ratio 260/280
D134.2 114 nd
D134.2 84,4 nd
D149.2 140 nd 
=>the measurement of the absorbance was so instable, that we have prefered to do it again, 
we do it by an another thechnik : Analysis on gel.

Ligation

Protocol

Ligation Name Vector Name Volume Vector (µL) Insert Volume Insert (µL)
L183 D187 D134
L184 D198 D149
L185 D199 D149
