Mutagenesis Primers Set Up
Purpose: To set up primers at the correct concentration to perform the QuikChange XL Site-Directed Mutagenesis.
- Primers have to be set up to have a concentration of 125 ng/µL. The primers were ordered from the synthesis lab at the University of Calgary
The following are the concentrations:
| Primer | 260/280 | 260/230 | Concentration [ng/μL] | Reading/2.5 [ng/μL]
|
| ''luxCDABE-M-F | 1.52 | 2.33 | 409.5 | 163.8
|
| ''luxCDABE-M-R | 1.58 | 2.86 | 479.8 | 191.2
|
- Checked if we have NZY+ broth prepared (found in freezer).

Construction Digest to Move From pCR2.1-TOPO to psB1AC3 Vector
- Objective: The LuxOD47E gene in now in linear form with the Biopbrick restriction sites attatched. We now want to get it into the psB1AC3 vector,
- Protcol: To do this, we will digest both the gene and the vector in two ways: one way with EcoRI and PstI and one way with XbaI and PstI
- Insert tube 1- DNA to approximately [600ng/uL]= 3.1uL
ddH2O up to 35 uL- 31.9 uL
4 uL REact 2 Buffer
1 uL XbaI restriction enzyme
1 uL PstI restriction enzyme
- Insert tube 2- same as for tube one, but with EcoRI restriction enzyme in place of XbaI restriction enzyme.
- Vector tube 1- psB1AC3 to [200ng/uL], REact 2 Buffer, XbaI restriction enzyme and PstI restriction enzyme
- Vector tube 2- same as for tube one, but with EcoRI restriction enzyme in place of XbaI restriction enzyme.
- Placed in 37 C waterbath for 2,5 hours followed by heat deactivation for 10 minutes in a 65 C heating block.

A Display for Quorum Sensing
I have returned to the avatar I made to sense a specific object and decided to use it to create a primitive quorum sensing system. To do so, it can no longer use the collision event in order to detect the presence of another object, but will have to use a sensor instead. I have decided to abandon the script to attach the object to a user’s original avatar and work on getting the sensor event to work for me. This will involve:
- Creating a variable to keep track of how many of the same objects are around each other. This may be determined by detecting the names of the objects around them
- Determining the range of the sensor so that the bacteria do not sense each other so easily that the point of what they are doing is lost
- Have the bacteria glow in response to a threshold level of bacteria. I will most likely have the bacteria as a display so I would like to keep them within a certain area, most likely in a small section of the synthetic kingdom
- Organize an explanatory note card for the quorum sensing bacteria
I have also begun planning out a restriction digest activity, which I will continue to work on tomorrow.

Shadowed Jeremy in Colony PCR & Restriction Digest
Purpose of Colony PCR: to see if the gene size that we constructed has been uptaken by the bacteria.
Method: please refer to protocol page on the wiki.
We used Lux PQ-F/R primers.
Note to self: pTaq DNA polymerase is always added last.
Purpose of RD: To verify the size of the Lux PQ construct
With digested with EcoRI +PstI in tubes 1-6 and with XbaI + Pst in tube 6 and tube 8 was the negative control.
Before running on gel:
-add 5 microL PCR product
-add 2 microL orange dye
- add 15 microL ddH2O
so that the total volume is 20 microL.
Then I helped to make the 0.8% agarose gel. We ran the digest at 90V.

Colony PCR of LuxOD47A BBk
Purpose: To isolate the colonies in which LuxOD47A on psB1AC3 was successfully transformed
Protocol:
We conducted a colony PCR of the colonies that grew on the overnight plates as a preliminary verification that our LuxOD47A BBk sequences on pSB1AC3 plasmids were properly transformed into the cells. We prepared tubes for the six largest colonies from each sample (initially formed with EcoRI and XbaI), for a total of twelve colony PCR tubes. As this process is only for verification (as opposed to LuxOD47A BBk formation from the gradient PCR with gene-specific BBk primers), the high fidelity afforded by the Platinum Pfx polymerase is not necessary, so the less-expensive and sufficiently-reliable Platinum Taq polymerase - and the corresponding Taq PCR buffer, with MgCl2 instead of MgSO4, was used instead in the Master Mix. Forward and reverse LuxOD47A-specific primers (without BioBrick sites) were used in the sequence amplification. We completed the Master Mix by adding dNTPs and double-distilled water, and then evenly distributed 650 uL of it across thirteen tubes (twelve for the colony testing and one negative control), each containing 50 uL aliquots of Master Mix. To add DNA to our relevant tubes, we delicately touched a pipette tip to a colony of interest and immediately inserted the bacteria-infested tip into the respective PCR tube. This was done for every tube except the negative control, which only contained Master Mix.
We then proceeded to run the colony PCR. Unlike the gradient PCR, the annealing temperature does not vary between wells and is set at 5 degrees C below the primer annealing temperature of 60 degrees C. The purpose of each step in the process is consistent, however. The Platinum Taq polymerase was activated in a 6 minute initialisation step at 94 degrees C. 36 cycles of a denaturation step (30 seconds at 94 degrees C), an annealing step (45 seconds at 55 degrees C) and an extension step (90 seconds at 72 degrees C). This was followed by a 10 minute final extension at 72 degrees C, and held at 4 degrees C once the PCR was complete.
Results: These are shown below. The bands are an appropriate size, but the negative control lane is not distinct from the other lanes. We progressed anyway with our restriction digest verification. Restreaks were also made for each of the colonies that were tested in the colony PCR.
