Digestion of RBS-phaC-RBs-phaA-RBS-phaB-RBS-eYFP-dT-pSB1A2 and ptet-pSB1A2

To make a construct of ptet-RBS-phaC-RBS-phaA-RBS-phaB-RBS-dT-pSB1A2, we digested RBS-phaC-RBs-phaA-RBS-phaB-RBS-eYFP-dT-pSB1A2 with XbaI & PstI, ptet-pSB1A2 with SpeI & PstI. Insert (RBS-phaC-RBs-phaA-RBS-phaB-RBS-eYFP-dT-pSB1A2)

Ethanol precipitation of RBS-phaB-RBS-eYFP-dT and RBS-phaC-RBS-phaA-pSB1A2

  1. Added 5 ul of NaoAc, 1.5 ul of glycogen and 125 ul of 100% ethanol.
  2. Centrifuged in 15000 rpm, 15 min at 4C.
  3. Remove supernatant and added 220 ul of 70% ethanol.
  4. Centrifuged in 15000 rpm, 10 min at 4C.
  5. Remove supernatant and air drying in room temperature then added 5 ul of DW.
[[image:|thumb|ethanol precipitation result]] We confirmed that the concentration of Insert DNA solution is 60~70 ng/ul and Vector DNA solution is about 20~30 ng/ul.

Ligation of RBS-phaB-RBS-eYFP-dT and RBS-phaC-RBS-phaA-pSB1A2

Transformation of RBS-phaC-RBS-phaA-RBS-phaB-RBS-eYFP-dT-pSB1A2

Transformation of JM109.

  1. Mixed 2 ul RBS-phaC-RBS-phaA-RBS-phaB-RBS-eYFP-dT-pSB1A2 ligation product to 50 ul of thawed competent cells on ice.
  2. Incubated on ice for 30 min.
  3. Mixed 350 ul of LB.
  4. Prepared and Labeled two plastic plates with LB plate medium which contained appropriate antibiotics (LBA).
  5. Plated 300 ul of the culture onto first dish and spread.
  6. Mixed 450 ul of LB to 50 ul of the culture and plated 300 ul of it onto second dish and spread.
  7. Incubated the plates at 37C for 17 hours.

Colony PCR of pBAD-RBS-eCFP-RBS-Ag43-dI-pSB1C3

We did colony PCR two times.

DNA solution 4 ul
Kapa-Taq(Taq polymerase) 10 ul
Forward Primer(200bp down primer) 0.8 ul
Reverse Primer(ag43-f4 primer) 0.8 ul
DW 4.4 ul

Cycle:2~4 x 35


We used N1 (DW only) and N2(pBAD-RBS-Ag43-dT-pSB1A2)as controls. Desired product is about 702bp.

Target products didn't exist in all samples. We noticed the reason why such results shown is that we used incorrect pSB1C3 DNA solution which isn't confirmed the sequence. We'll try the synthesis once again in today.

Digestion of pBAD-RBS-eCFP-RBS-Ag43-dT-pSTV28 and pSB1C3

To make a construct of pBAD-RBS-eCFP-RBS-Ag43-dT-pSB1C3, we digested pBAD-RBS-eCFP-RBS-Ag43-dT-pSTV28 with EcoRI & SpeI and pSB1C3 with EcoRI & SpeI. Insert (pBAD-RBS-eCFP-RBS-Ag43-dT-pSTV28)

  2. Centrifuged in 15000 rpm, 15 min at 4C.
  3. Remove supernatant and added 220 ul of 70% ethanol.
  4. Centrifuged in 15000 rpm, 10 min at 4C.
