September 3rd

Colony PCR of eCFP-RBS-pSB1A2

DNA solution 4 ul
Kapa-Taq(Taq polymerase) 5 ul
Forward Primer(EX-F primer) 0.5 ul
Reverse Primer(PS-R down primer) 0.5 ul
Total 10 ul

2 95 30
3 68.9 30

6 4 HOLD

Cycle:2~4 x 35

We used N1 (DW only) and N2 (ptetR-RBS-eCFP-dT-pSB1A2) as controls. Desired product is about 776bp.

Colony PCR result


We confirmed that about 70% of ligated DNA formed our desired construct. We selected No.2 and 5 colony for incubation and store No.7 and 8 colony mixture at 4C.

Incubation of eCFP-RBS-pSB1A2 for mini-prep

  1. Prepared 2 ml LBA into culture tubes.
  2. Re-suspended 2 colony mixture (No.2 and No.5 respectively).
  3. Incubated at 37C for hrs.


Estimation of concentration of eCFP-RBS-pSB1A2 and pBAD-RBS-pSB1A2

No.2,5 means the colony number of colony PCR of eCFP-RBS-pSB1A2. [[image:|thumb|electrophoresis result]] We estimated the concentration of eCFP-RBS-pSB1A2 is 30 ng/ul and pBAD-RBS-pSB1A2 is 50ng/ul.


Digestion of eCFP-RBS-pSB1A2 and pBAD-RBS-pSB1A2

To make a construct of pBAD-RBS-eCFP-RBS-pSB1A2, we digested eCFP-RBS-pSB1A2 with XbaI & PstI and pBAD-RBS-pSB1A2 with SpeI & PstI. And we digested eCFP-pSB1A2 with XbaI & SpeI as a control for confirmation of the ability to digest. Insert (eCFP-RBS-pSB1A2)

From this image, we confirmed that DNA were digested into fragments and all of restriction enzyme worked.

Ethanol precipitation of digestion products (eCFP-RBS and pBAD-RBS-pSB1A2) and estimation of concentration

  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 estimated the concentration of ethanol presipitation products.The concentration of Insert DNA solution is about 20 ng/ul and Vector DNA solution is about 50 ng/ul.

Ligation of eCFP-RBS and pBAD-RBS-pSB1A2

Vector DNA (50 ng/ul) 1.5 ul

Transformation of pBAD-RBS-eCFP-RBS-pSB1A2

  1. Mixed 2 ul pBAD-RBS-eCFP-RBS-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 25 hours.


Digestion of ptet-RBS-eYFP-dT-pSB1A2 and pSTV28

To make a construct of ptet-RBS-eYFP-dT-pSTV28, we digested ptet-RBS-eYFP-dT-pSB1A2 with EcoRI & PstI and pSTV28 with EcoRI & PstI. And we digested Ag43-dT-pSB1AK3 with HindIII. Insert (ptet-RBS-eYFP-dT-pSB1A2)
