Restriction digest (EcoRI + PstI) 37°C, 2h

  • Ligation product (see 09/07/2010):(P-plasmid-E-X-attC-S) + (X-dbter-attC-mRFP-S-P)1 µL
  • Ligation product (see 09/07/2010):(P-plasmid-E-X-attC-S) + (X-dbter-attC-mRFP-S-P)5 µL

DNA Gel electrophoresis (agarose 1,0% w/v) (check the function of T4 ligase and the ligation product)
2 µL of EtBr was added in the gel

Protocol (7 wells)

  • 5 µL of ladder 1Kb + T4 ligase (incubation 10 min at room temperature) + 1 µL of loading buffer 6x
  • 5 µL of ladder
  • 5 µL of ligation product (1 µL) digested by EcoRI and PstI + 1 µL of loading buffer 6x
  • 5 µL of ligation product (5 µL) digested by EcoRI and PstI + 1 µL of loading buffer 6x
  • 5 µL of ligation product (5 µL) non digested + 1 µL of loading buffer 6x
  • 5 µL of ligation control (vector without insert) + 1 µL of loading buffer 6x
  • 5 µL of minipreped DNA (attC) + 1 µL of loading buffer 6x

Migration : 50V, 1h30

Ligation (T4 ligase)
Ligation overnight in cold water
vector : P-plasmid-E-X-attC-S (pSUlib - attC KanR cut by SpeI and PstI)
insert : X-dbter+attC+mRFP-S-P (pSUlib EX-B0015-attC-S-mRFP1-P KanR cut by XbaI and PstI)

Stéphane and Raphaël

Restriction digest 45min at 37°C, then overnight at -20°C

  • BBa_J23119 cut by EcoRI + SpeI -> wrong restriction enzymes ! (use SpeI + PstI)
  • BBa_J23110 cut by EcoRI + SpeI -> wrong restriction enzymes ! (use SpeI + PstI)
  • BBa_J37033 cut by XbaI + PstI
  • BBa_R0062 cut by EcoRI + SpeI -> wrong restriction enzymes ! (use SpeI + PstI)
  • BBa_E0240 cut by XbaI + PstI
