To make a construct of pBAD-RBS-eCFP-RBS-Ag43-dT-pSTV28 by 3piece ligation, we digested pBAD-RBS-eCFP-RBS-pSB1A2 by EcoRI and SpeI, Ag43-dT-pSB1AK3 (previously digested by HindIII) by XbaI and NotI, and pSTV28 by EcoRI and NotI. Then we digested pT7-RBS-pSB1C3 by XbaI and SpeI as a control for confirmation of the ability of restriction enzyme.

To make a construct of pBAD-RBS-eCFP-RBS-Ag43-dT-pSTV28 by 3piece ligation, we digested pBAD-RBS-eCFP-RBS-pSB1A2 by EcoRI and SpeI, Ag43-dT-pSB1AK3 (previously digested by HindIII) by XbaI and NotI, and pSTV28 by EcoRI and NotI. Then we digested pT7-RBS-pSB1C3 by XbaI and SpeI as a control for confirmation of the ability of restriction enzyme.

  • We noticed that this step was actually 68.9 degree after reaction.

We used N1 (DW only) and N2(pBAD-RBS-Ag43-dT-pSB1A2)as controls. Desired product is about 542bp.

Colony PCR result

Because of mis-setting the PCR program, we failed to amplify desired DNA fragment so we retried the colony PCR in same reagent, correct PCR machine program.

Colony PCR result

We noticed that the ligated DNA contains at least Ag43-dT-BioBrick_Suffix complex. We selected No. 2,4 for incubation for plasmid extraction and No. 5,6 for Aggregation check.

We suppose the Insert DNA (RBS-phaB-RBS-eYFP-dT) has contained Vector-dimer DNA as contamination. But desired DNA fragment (about 1600 bp) bond also appeared in the result of migration. We picked up the fragment and extracted from gel.

Digestion of pBAD-RBS-eCFP-RBS-Ag43-dT-pSTV28 and pT7-RBS-pSB1C3

To make a construct of pBAD-RBS-eCFP-RBS-Ag43-dT-pSB1C3, we digested pBAD-RBS-eCFP-RBS-Ag43-dT-pSTV28 with EcoRI and SpeI, and pT7-RBS-pSB1C3 with EcoRI and SpeI. As a control, we digested pT7-RBS-pSB1C3 with only EcoRI to confirm the digestibility of This DNA (The digestibility with SpeI has confirmed in August 26th).

digestion result

We confirmed 4 bonds in the result of Inset DNA digestion. A Bond which shows the highest concentration and places about 8k ~ 10k bp area would be pBAD-RBS-eCFP-RBS-Ag43-pSTV28 construct. We considered about it bond whether remained from digestion, or at first formed dimer and separated by digestion. In either case, our target product has about 5200 bp and there is appropriate bond. We extracted the target bond from TBE gel and went next step.

Ethanol precipitation of pBAD-RBS-eCFP-RBS-Ag43-dT on pSB1C3

  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. Removed supernatant and added 220 ul of 70% ethanol.
  4. Centrifuged in 15000 rpm, 10 min at 4C.
  5. Removed supernatant and dried out at room temperature, after that added 10 ul of DW.

Transformation of pBAD-RBS-eCFP-RBS-Ag43-dT-pSB1C3

Transformation ligation product into DH5α.

  1. Mixed 2 ul pBAD-RBS-eCFP-RBS-Ag43-dT--pSB1C3 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. Incubated for 2 hrs to get the resistance to Chloramphenicol.
  5. Prepared and Labeled two plastic plates with LB plate medium which contained appropriate antibiotics (LBC).
  6. Plated 300 ul of the culture onto first dish and spread.
  7. Mixed 450 ul of LB to 50 ul of the culture and plated 300 ul of it onto second dish and spread.
  8. Incubated the plates at 37C for 13 hrs.

Cycle:2~4 x 35

We used N1 (DW only) and N2(RBS-phaC-RBS-phaA-RBS-phaB-dT-pSB1A2)as controls. Desired product is about 1800~2000bp.

Colony PCR result

We noticed the ligated DNA contains phaB-something-SP sequence and the length is about 1600~1800bp, at least over 1000 bp. We selected No. 1,2 for incubation for plasmid extraction and No. 3,4 for stock at 4C.

Incubation of RBS-phaB-RBS-eYFP-dT-pSB1A2 for plasmid extraction

  1. Prepared 2 ml LBA into culture tubes.
  2. Re-suspended 2 colony mixture (No. 1 and No. 2 respectively).
  3. Incubated at 37C for 20 hrs.
