Week 1 (May 1-May 5, 2017)
We are all fully trained in laboratory safety! We each did 6 online courses and attended 2 seminars on lab safety and biosafety. In the lab we practiced important protocols, including media preparation, overnight culture inoculation, preparing chemically competent cells, and transforming chemically competent cells. We also did inventory, organized the lab, and began an order sheet for supplies that we will need throughout the summer. Also, we began to research ways that we will be able to use synthetic biology to extract synthesized PHB from cells, without the use of traditional chemical or mechanical lysis.
Week 2 (May 8-May 12, 2017)
We practiced more important laboratory techniques: plasmid minipreparation, preparing master plates of transformed E.coli, cPCR, and agarose gel electrophoresis. Outside the lab, we narrowed down our possible extraction methods to either an acetate-based autolysis system or a hemolysin type I secretion system. The autolysis method depends on the change in concentration of VFAs, specifically acetic acid, as the VFAs are depleted during PHB synthesis. However, we decided that there were too many unknowns and other factors at play for this system. Therefore, we decided to use the hemolysin type I secretion system. We uploaded our parts onto Benchling and began designing our plasmid, with the goal of ordering our parts early next week! Some modifications to the parts we uploaded to Benchling were made; Flag tags for easier protein expression validation were added to each coding sequence and restriction sites were removed to make the parts RFC10,12,21,23,25, and 1000 compatible.
Week 3 (May 15-May 19, 2017)
This week we finished editing our secretion parts before ordering them from IDT. Our complete part (phasin-HlyA tag, HlyB, HlyD) was split into two separate gBlocks because it was too large for one. A gBlock with just the phasin-HlyA tag was ordered as well so that we could compare secretion of the endogenous E.coli secretion system to our system with upregulated HlyB and HlyD. Restriction sites for the HINDIII enzyme were added to the ends of our gBlocks so they could be easily ligated together. All stop codons were changed to TAA because it is the most effective stop codon in E.coli. Also, codons were optimized before ordering using this tool
Week 4 (May 23- May 26, 2017)
Team members Jacob and Sam began working on the Interlab Study. To begin, chemically competent DH5𝛼 E.coli were made and stored at -80°C in glycerol stocks, PSB buffer was made and diluted several times to develop a standard absorbance curve for the study, and the plate plate reader was calibrated. Actual work on the Interlab Study was not very successful because there was little to no growth on plates of the transformed DH5𝛼, even though they were incubated at 37°C for two days. We also had a very informative tour of the Pine Creek Wastewater Treatment Plant in Calgary. Many questions were answered and the information we have gained will be used in deciding what application route our project will take.
Week 5 (May 29- June 2, 2017)
Due to the lack of growth on the Interlab Study plates last week, chemically competent DH5𝛼 E.coli were made again because there may have been issues with the first set of competent cells created. However, there was still no growth on the plates inoculated with transformed cells. On a positive note, our constructs from IDT that were ordered in week 3 arrived! We can hopefully begin work with our parts next week. Outside of the lab, lots of work was dedicated to researching the pros and cons of the four possible applications of our project (space, wastewater treatment, landfill leachate, and developing countries). The entire team will make its final decision about the application early next week.
Week 6 (June 5- June 9, 2017)
Again, Jacob and Sam’s work on the Interlab Study was unsuccessful. We tried using different protocols for making chemically competent cells and transforming those cells, but nonetheless there was still no growth after 24h incubation. This strongly suggests that there is an issue with our DH5𝛼 cells so next week we will get new cells and try again. Because our cells are so problematic, work has not yet begun with our actual secretion construct from IDT. Lalit and Kaitlin prepared samples for gel electrophoresis and all of the necessary supplies that will be needed on Lalit’s trip to Winston Churchill High School on Monday, June 12, 2017, where he will present to Grade 11 Students about synthetic biology, practice gel loading, and perform strawberry DNA extraction experiments with them. After long discussions and consultations with experts and industry we decided that applying our project to creating PHB in space, ie. on future Mars colonizations, would be the best choice and would make the most sense for our synthetic biology approach.
June 11, 2017- Geekstarter iGEM Workshop, presented by MindFuel and Alberta Innovates
Today was an iGEM workshop hosted by Geekstarter that was attended by the University of Alberta, University of Calgary, Urban Tundra High School, and University of Lethbridge iGEM teams. There were four speakers who gave ½ hour presentations on an introduction to syn bio, mathematical modeling, wiki design, and integration of art into syn bio. Later, we had the chance to speak with each presenter individually and ask questions specific to our project. Also, there was a collaboration period where we got to mingle with the other teams and discuss our projects with them. Overall it was a successful day where we learned a lot from the presenters and found out about some possible collaborations with the other teams.
Week 7 (June 12- June 16, 2017)
On Monday, June 12 Lalit and Sam visited Winston Churchill High School to present to Grade 11 students about Synthetic Biology (which we prepared for in Week 8). We acquired new E.coli DH5α cells from Dr. Dong and transformed them for the interlab study and finally, there was successful transformation and colony growth of GFP cells after overnight incubation. This supports the theory that there was in fact something wrong with the cells that we were previously using. Therefore, for our work throughout the summer we will continue using these DH5α cells from Dr. Wong. Jacob and Sam used the new cells to successfully complete the laboratory component of the interlab study this week. Also, we performed a miniprep of psB1c3 plasmids from RFP E.coli Top10 for use with our secretion insert in the following weeks.
Week 8 (June 19- June 23, 2017)
Our parts from IDT (that arrived in Week 5) were re-suspended and were stored at -20℃, where they will remain for the rest of the summer. To prepare ourselves for work with our IDT constructs we performed various diagnostic tests with restriction enzymes. To do this, we digested each psb1c3 with RFP insert and psb1c3 with GFP insert with SpeI and EcoRI and confirmed the digest on a 1% agarose gel. After some troubleshooting, we obtained two distinct bands on the gel, representing the psB1c3 backbone and RFP/GFP insert, by the end of week. This indicates that these enzymes are functional and can be used on our IDT parts. Also, we have been having difficulty creating chemically competent E.coli DH5α cells so we are going to try a different protocol next week. Outside of the lab, Jacob and Sam completed and submitted the online portion of the Interlab Study this week. Kaitlin and Lalit attended various meetings with other members of the team.
Week 9 (June 26- June 30, 2017)
After confirming on a 1% agarose gel that the plasmids were linearized last week, we ran the samples on a 3% low melting point agarose gel to extract both the plasmid backbones and the RFP/GFP inserts. Then, to test our ligase, we ligated the extracted GFP inserts to the extracted RFP backbones and the extracted RFP inserts were ligated to the extracted GFP backbones. As we expected, bacteria transformed with the GFP inserts-RFP backbone grew green colonies and bacteria transformed with RFP inserts-GFP backbone grew red colonies. This indicates that the restriction enzymes and ligase were functioning properly and they can be used with our precious IDT parts. Jacob and Sam tested out a new protocol for making chemically competent E. coli DH5α cells from Richard Moore, who is part Dr. Dong’s lab here at the Foothills Hospital. They tested the cells’ competency with 100 ng/µL RFP. The transformed cells grew extremely well with numerous colonies and a high transformation efficiency. Finally, we have a protocol for making competent cells that works! Our IDT parts were digested and ligated into their corresponding backbones:
| Part/Insert | Digested with... | Backbone |
|---|---|---|
| Phasin-HlyA Tag | EcoRI, SpeI | psB1c3 |
| Secretion Part 1 | XbaI, HindIII | pET29B |
| Secretion Part 2 | HindIII, NotI | pET29B |
Then we transformed our ligated backbones and parts into our chemically competent E. coli DH5α cells.
Week 10 (July 3-July 7, 2017)
We performed plasmid miniprep on the colonies of E. coli DH5α cells transformed with our ligated backbones/parts last week for digest confirmation on a 1% agarose gel. Throughout the week we chose 8 colonies from phasin-HlyA, 8 colonies from SP1, and 2 colonies from SP2 (because there were only two transformed colonies that grew) to be digest confirmed. Each colony was left undigested as a control, double-digested with the same enzymes we used last week to check for the insert size, and digested with another random enzyme to check for insert directionality:
| Part/Insert | Backbone | Digested with…. | Expected Band Sizes |
|---|---|---|---|
| Phasin-HlyA Tag | psB1c3 | EcoRI, SpeI | 2.0 kb, 889 bp |
| Secretion Part 1 | pET29B | XbaI, HindIII | 5.2 kb, 2.4 kb |
| Secretion Part 1 | pET29B | HincII | 6 kb, 1.5 kb |
| Secretion Part 2 | pET29B | HindIII, NotI | 5.4 kb, 2.2 kb |
| Secretion Part 2 | pET29B | EcoRV | 6.1 kb, 1.5 kb |
By the end of the week we determined that only colony 1 of the phasin-HlyA tag had successfully received a plasmid with our part, as can be seen in the image below , where there is roughly 2 kb and 900 bp sized bands (Double digested colony 1 with EcoR1 and Spe1) . Our other parts were not successfully transformed into our cells so next week we will need to re-transform chemically competent E. coli DH5α with Secretion Part 1 and Secretion Part 2 to obtain more colonies, which could possibly have our insert properly ligated into the pET29B backbone.
