1. Inactivate restriction enzyme from reactions prepared on September 14th, 20 min at 80º C.

2. Run gel to check restrictions and PCR made on September 14th.

Lanes: 1,8) Green ladder; 2) pSB3K3 + J23101 SpeI-PstI restriction; 3) Δ RBS + GFP E0040 XbaI-PstI restriction; 4) BBa_I20260 Min-BP REV-Suffix FWD PCR product (tube 7); 5) BBa_I20260 Min-BP REV-Suffix FWD PCR product (tube 8); 6-7) Claudia’s samples.

3. Purify PCR product of BBa_I20260 Min-BP REV-Suffix FWD using the High Pure PCR Product Purification Kit Roche.

4. Make restrictions to pure PCR product, plasmid pSB3K3 + Minimum Blue Promoter with SpeI-PstI.

  • SpeI-PstI double restriction methods:
DNA -> 15 ul
Buffer 2 -> 4 ul (10% of total volume)
BSA -> 1 ul
SpeI -> 2 ul
PstI -> 2 ul
HPLC -> 16 ul (to complete total volume of 20ul)
Incubate at 37º C for 2 hrs.

5. Inactivate enzyme from pSB3K3-Min. Blue Promoter SpeI-PstI restriction, 20 min. at 80 ºC.

6. Make the following ligations:

  • pSB3K3-J23101 SpeI-PstI (3ul) with Δ RBS-GFP E0040 XbaI-PstI (5ul).
  • pSB3K3-Min. Blue Promoter SpeI-PstI (2ul) with Δ RBS-GFP E0040 XbaI-PstI (5ul).
  • Ligation methods (Total volume 20ul):
DNA -> Volume of each part to be ligated is indicated above.
Buffer for T4 DNA ligase 5X -> 4ul (Final concentration 20%)
T4 DNA ligase -> 1ul
HPLC -> Complete total volume (20ul)
Incubate overnight at 16ºC
Mix well (vortex) buffer and reaction tubes, unfreeze buffer on ice.
