Adrian

Gel extraction optimisation

Hypothesised that the Binding buffer has a problem/DNA does not bind to column

1: 2X promega binding buffer volume

2: Increase incubation time for binding to 5min

Switch binding buffer to that of thermo scientific PCR purification kit

Use sodium acetate if available? TO facilitate stronger binding to column

Results

1: ~10ng/ul

2: ~9ng/ul

not succesful

further optimisation-> warm buffer, incubate for 5min

elute in 30/20ul smaller volumes

Colony PCR of invasin

Picked out 8 colonies (marked 1-8) from BBa_K299812 plate stored at 4deg (Adrian, 12/7).

Colony PCR using prefix suffix primers for first 4 rxn and universal primers VP & VF2 for last 4 rxn. Used thermocycler "Colony" protocol.

Also constituted dNTP w 2.5mM of each atcg triphosphate.

Yanting

100V at 30min. Ladder, 4 prefix suffix rxn, 4 universal primers rxn. Saved as “7.15_inv colony”.

When I ran for longer (after storing gel at 4deg), the bands were longer but the 250bp marker as well as the primer-dimers are pretty close to dye front.

Yunting

Placed BBa_K299812 plate in incubator for overnight growth.

Yanting and Yunting

Colony PCR of 8 colonies (marked A-H) from BBa_K299812 plate, and also spotted on a save plate. Both plates placed back in incubator.

Primer conc=0.5 uM, template DNA dissolved in 10ul h20.

Thermocycler “colony_inv” protocol, with adjusted extension time and annealing time&temp from standard “colony” protocol.

100V for 34min.

Tubes 1-2: FP-prefix, RP-suffix.

3-4: FP-VF2, RP-VR.

5-6: FP-prefix, RP_Inv_M2.

7-8: RP-suffix, FP_Inv_M1.

No template control with FP-prefix, RP-suffix.

[Note: RP_M2 = FP_M2. Check future uses agn seq on the primer master file. Just in case, the sequence used in this expt is INV_FP_M2->GCTCATTATAGTCCGCGAAATCACG].

Gel image saved as “7.17_inv colony.sgd” (handphone pic below).

Results: Tubes 3&4 with universal primers VF2 VR have a band between 4&5kb - Inv+LLO is 4.1kb, probably are positive colonies.

Tubes 1&2, 5&6 have bands <750bp as well as primer dimers (but the annealing temperature was calculated for prefix suffix primers not universal ones…I’ll try thermo-gradient thermocycler protocol next time).

Expected band size for 5&6 (FP-prefix, RP_Inv_M2 (ends 1928)) = 1.9kb.

No bands for tubes 7&8. Expected band size for 7&8 (RP-suffix, FP_Inv_M1 (starts 1046)) = 2.2kb.

Results Notes:

Too much template DNA (~250ng). Separate the universal primers (to avoid differing extension time).

Yanting

RE digest of inv/hyl plasmid with EcoRI and PstI for 2 hours at 37oC.

Lane 1-4: 1kb ladder, 100bp ladder, RE of colony C, RE of colony D.

Size is correct: 4kb main band (inv+hly part) and 2kb (plasmid backbone). These plasmid DNA should have the part.

100V for 45min (can run for longer).

Result:

Lane 1: 1kb ladder; lane 2: 100bp ladder;

lane 3-7: FP prefix + RP suffix (5 repeats with increasing annealing temperatures) has 2 bands ~800 bp & 100-200bp (probably non specific bands, will lower # of cycles in future, use higher annealing temp, lower annealing time).

Expected size of inv+hly part is 4.1kb.

lane 8-9: VF + M2 has a thick band 800-900bp.

Expected size is 600+130bp (VF adds ~130bp compared to FP_prefix) .: doesn’t seem to be correct….

lane 10-11: VF + inv F has no bands. Expected is at least 200bp (bcos universal primers).

lane 12: VR + inv F seems to have a small band <100bp. Non specific amplification?

Expected is 1.5+0.1 kb (from VR).

Rationale: The invasin gene in the invasin+listerolysin plasmid should remain intact and be expressed, leading to an invasion phenotype

Objective: Screen invasion phenotype of BL21 and BL21+invasin-listerolysin Biobricks part

Experiment details

Cells were passage 2 Seed 0.5mL of 5x10^5 HEK293T cells/mL and 1x10^6 in wells of 24-well plates, grow overnight.

Determine cell confluency with microscopy the next day - 80-90% confluency

All strains were grown overnight in 3mL LB broth

For 5x10^5 cells

100ul of 10^9 cells/mL was used for moi 200

100ul of 2X dilution of 10^9 cells/mL was used for moi 100

100ul of 4X dilution of 10^9 cells/mL was used for moi 50

100ul of 5X dilution of 10^9 cells/mL was used for moi10

Result Lawn on all plates HEK293T cells detach too easily.

Grow for 24 hours in the future and do minimal, and gentle washing. For next experiment, 0.5x10^6 and 1x10^6 cells wre seeded 1000ug/mL kanamycin for 1 hour is sufficient for kill step

no contamination in uninfected control

There is invasion in background BL21 strain as well

All mois showed high percentage of infection

In future use moi 10:1 and plate up 10^2 to 10^5 dilution for countable colonies

Workshop

píc

One of the participants taking a closer look at GFP-tagged E. coli under our very own SPS microscope.

The SPS iGEM Team of 2015 hosted a genetic engineering workshop for students from the Faculty of Science on 5th August 2015, in the Active Learning Room and the SPS Wet Lab. The workshop aimed to equip science students with an understanding of both the techniques of synthetic biology, and its risks and rewards. Participants were given the opportunity to be immersed in both the theoretical and wet lab components of synthetic biology.

Students were first guided through the concepts of genetic engineering, and the available wet lab tools and techniques used. After some light refreshments, they then got a chance to try their hands at designing their very own gene vectors with a fun set of theoretical puzzles.

One of the workshop facilitators explaining the process of constructing a genetic vector.

Participants and facilitators hard at work figuring out genetic puzzles

After lunch, the participants performed Fusion PCR (Polymerase Chain Reaction) and performed bacterial transformation in the SPS Wet Lab. They also had a look at green fluorescent protein (GFP) expressed in E. coli, as an example of one of the methods that are commonly used to quantify protein expression.

Participants beginning PCR in the SPS Wet Lab!

Loading a gel is hard work – participants ran a DNA gel to confirm if their PCR reaction was successful

All in all, both the workshop participants and facilitators spent an enjoyable day both learning and sharing about genetic engineering. The SPS iGEM Team of 2015 would like to thank all participants for spending their day with us! We would also like to thank Science Dean’s Office for their kind sponsorship, as well as the SPS staff and SPS community for their support.

Interview

safety

Biosafety in our project involves minimising the risks to the researchers working in the laboratory, as well as the general public in future medical applications based off our research.

Safety when handling biological organisms

Non-pathogenic strains of E. coli K-12 strains BL21 and dH5α from Life Technologies were used for bacterial cloning of plasmids and expression of proteins of interest. These strains are Risk group 1 and were handled in a BSL2 Biosafety cabinet. The E. coli strain carrying the Biobrick BBaK299812 (containing parts derived from Risk group 2 organisms) was handled as a Risk Group 2 agent. Mammalian cell line HEK293T is classified under Risk group 2, and was also cultured in a BSL2 Biosafety cabinet.

Safety in Project Design

In our project, we aim to engineer non-pathogenic E. coli as a vector to deliver a potential drug into the tumour core. We use the Biobricks Part BBa_K299812 (http://parts.igem.org/wiki/index.php?title=Part:BBa_K299812), which contains the invasin gene from Yersinia pseudotuberculosis and the listerolysin O gene from Listeria monocytogenes. The Invasin protein allows for bacteria to enter mammalian cells, while Listerolysin O is a pore-forming protein that enable bacteria to escape the endosome. These two proteins are involved in pathogenesis of their respective bacterial species.

The Invasin and Listerolysin proteins enable our E. coli to enter mammalian cells, and escape the endosome, where they can subsequently deliver an encoded therapeutic to kill the tumour cell. To ensure that these proteins are only expressed under the conditions of the tumour microenvironment, the invasin and listerolysin proteins will be placed under the control of an anaerobic promoter, and a quorum sensing system.

Safety in Our Lab

All our team members have undergone Chemical, Biological and Fire Safety Training from the Office of Safety, Health and Environment (OSHE http://www.nus.edu.sg/osh/), the department in charge of Laboratory and Work Safety at the National University of Singapore

For each protocol used for our experiments, we have a separate risk assessment. Please refer to our ‘protocols’ page for more information.

Our laboratory is equipped with biological and chemical spill kits, and all members of our iGEM Team are trained to handle Biological and Chemical Spills. Our laboratory is classified as Biosafety Level 2, according to the classification by the Wolrd Health Organisation (WHO) and the Genetic Modification Advisory Committee of the government of Singapore (http://www.gmac.gov.sg/).

Bacterial work and Mammalian cell culture are performed in separate BSL2 Biosafety Cabinets, while DNA work is done on the bench. No cytotoxic reagents are used in our laboratory; Sybr Safe DNA stain is used rather than Ethidium Bromide. Liquid biological waste is decontaminated using 10% Bleach, while Solid biological waste is sent for incineration in a local incineration plant devoted to medical waste (Sembcorp http://www.sembcorp.com/en/business-on-site-services-solid_waste_management.aspx).

Safety Requirements for iGEM Participation

For the fulfillment of requirements for safety from the iGEM foundation, we have submitted the ‘About our lab’ safety forms (https://2015.igem.org/Safety/About_Our_Lab?team_id=1804) and the ‘Final Safety form (Yihan will complete this later to the deadline as currently can’t confirm what we are submitting to parts registry. Just put in first)’

We have also performed a check-in (https://2015.igem.org/Safety/Check_In) for the Biobricks Part (Bba_k299812 http://parts.igem.org/wiki/index.php?title=Part:BBa_K299812), which contains the invasin gene from Yersinia pseudotuberculosis and the listerolysin O gene from Listeria monocytogenes.

Gold

In addition to the Bronze and Silver Medal requirements, your team must convince the judges you have achieved at least two of the following goals:

1. Choose one of these two options: (1) Expand on your silver medal Human Practices activity by demonstrating how you have integrated the investigated issues into the design and/or execution of your project. OR (2) Demonstrate an innovative Human Practices activity that relates to your project (this typically involves educational, public engagement, and/or public perception activities; see the Human Practices Hub for information and examples of innovative activities from previous teams).

2. Help any registered iGEM team from a high-school, different track, another university, or institution in a significant way by, for example, mentoring a new team, characterizing a part, debugging a construct, modeling/simulating their system or helping validate a software/hardware solution to a synbio problem.

3. Improve the function OR characterization of a previously existing BioBrick Part or Device (created by another team, or by your own team in in a previous year of iGEM), and enter this information in the part's page on the Registry. Please see the Registry Contribution help page for help on documenting a contribution to an existing part. This part must not come from your team's 2015 range of part numbers. Demonstrate a functional prototype of your project. Your prototype can derive from a previous project (that was not demonstrated to work) by your team or by another team. Show this system working under real-world conditions that you simulate in the lab.

Silver

In addition to the Bronze Medal requirements, your team must convince the judges you have achieved the following 3 goals:

1. Experimentally validate that at least one new BioBrick Part or Device of your own design and construction works as expected. Document the characterization of this part in the Main Page section of the Registry entry for that Part/Device. This working part must be different from the part you documented in Bronze medal.

2. Submit this new part to the iGEM Parts Registry. This part must be different from the part you documented in Bronze medal. (Submissions must adhere to the iGEM Registry guidelines.)

3. iGEM projects involve important questions beyond the bench, for example relating to (but not limited to) ethics, sustainability, social justice, safety, security, and intellectual property rights. We refer to these activities as Human Practices in iGEM. Demonstrate how your team has identified, investigated and addressed one or more of these issues in the context of your project.

Bronze

1. Register for iGEM, have a great summer, and attend the Giant Jamboree.

2. Complete the Judging form. Create and share a Description of the team's project using the iGEM wiki, and document the team's parts using the Registry of Standard Biological Parts.

3. Present a poster and a talk at the iGEM Jamboree.

4. Create a page on your team wiki with clear attribution of each aspect of your project. This page must clearly attribute work done by the students and distinguish it from work done by others, including host labs, advisors, instructors, sponsors, professional website designers, artists, and commercial services.

5. Document at least one new standard BioBrick Part or Device central to your project and submit this part to the iGEM Registry (submissions must adhere to the iGEM Registry guidelines). You may also document a new application of a BioBrick part from a previous iGEM year, adding that documentation to the part's main page.

+<p><em>One of the participants taking a closer look at GFP-tagged E. coli under our very own SPS microscope.</em>
+</p>
+<p>The SPS iGEM Team of 2015 hosted a genetic engineering workshop for students from the Faculty of Science on 5th August 2015, in the Active Learning Room and the SPS Wet Lab. The workshop aimed to equip science students with an understanding of both the techniques of synthetic biology, and its risks and rewards. Participants were given the opportunity to be immersed in both the theoretical and wet lab components of synthetic biology.</p>
+<p>Students were first guided through the concepts of genetic engineering, and the available wet lab tools and techniques used. After some light refreshments, they then got a chance to try their hands at designing their very own gene vectors with a fun set of theoretical puzzles.</p>

+<p><em>Participants and facilitators hard at work figuring out genetic puzzles</em></p>
+<p>After lunch, the participants performed Fusion PCR (Polymerase Chain Reaction) and performed bacterial transformation in the SPS Wet Lab. They also had a look at green fluorescent protein (GFP) expressed in <em>E. coli</em>, as an example of one of the methods that are commonly used to quantify protein expression.</p>

+<p>All in all, both the workshop participants and facilitators spent an enjoyable day both learning and sharing about genetic engineering. The SPS iGEM Team of 2015 would like to thank all participants for spending their day with us! We would also like to thank Science Dean&rsquo;s Office for their kind sponsorship, as well as the SPS staff and SPS community for their support.</p>

+<strong>Biosafety in our project involves minimising the risks to the researchers working in the laboratory, as well as the general public in future medical applications based off our research.</strong>
+<br></br>

+<h3>Safety when handling biological organisms</h3>
+<div>
+<p>
+Non-pathogenic strains of E. coli K-12 strains BL21 and dH5α from Life Technologies were used for bacterial cloning of plasmids and expression of proteins of interest. These strains are Risk group 1 and were handled in a BSL2 Biosafety cabinet. The E. coli strain carrying the Biobrick BBaK299812 (containing parts derived from Risk group 2 organisms) was handled as a Risk Group 2 agent. Mammalian cell line HEK293T is classified under Risk group 2, and was also cultured in a BSL2 Biosafety cabinet.
+</p>
+</div>
+<h3>Safety in Project Design</h3>
+<div>
+<p>
+In our project, we aim to engineer non-pathogenic E. coli as a vector to deliver a potential drug into the tumour core. We use the Biobricks Part BBa_K299812 (http://parts.igem.org/wiki/index.php?title=Part:BBa_K299812), which contains the invasin gene from Yersinia pseudotuberculosis and the listerolysin O gene from Listeria monocytogenes. The Invasin protein allows for bacteria to enter mammalian cells, while Listerolysin O is a pore-forming protein that enable bacteria to escape the endosome. These two proteins are involved in pathogenesis of their respective bacterial species.
+</p>
+<p>
+The Invasin and Listerolysin proteins enable our E. coli to enter mammalian cells, and escape the endosome, where they can subsequently deliver an encoded therapeutic to kill the tumour cell. To ensure that these proteins are only expressed under the conditions of the tumour microenvironment, the invasin and listerolysin proteins will be placed under the control of an anaerobic promoter, and a quorum sensing system.
+</p>
+</div>
+<h3>Safety in Our Lab</h3>
+<div>
+<p>All our team members have undergone Chemical, Biological and Fire Safety Training from the Office of Safety, Health and Environment (OSHE http://www.nus.edu.sg/osh/), the department in charge of Laboratory and Work Safety at the National University of Singapore</p>
+<p> For each protocol used for our experiments, we have a separate risk assessment. Please refer to our ‘protocols’ page for more information. </p>
+<p>Our laboratory is equipped with biological and chemical spill kits, and all members of our iGEM Team are trained to handle Biological and Chemical Spills.
+Our laboratory is classified as Biosafety Level 2, according to the classification by the Wolrd Health Organisation (WHO) and the Genetic Modification Advisory Committee of the government of Singapore (http://www.gmac.gov.sg/).</p>
+<p> Bacterial work and Mammalian cell culture are performed in separate BSL2 Biosafety Cabinets, while DNA work is done on the bench. No cytotoxic reagents are used in our laboratory; Sybr Safe DNA stain is used rather than Ethidium Bromide.
+Liquid biological waste is decontaminated using 10% Bleach, while Solid biological waste is sent for incineration in a local incineration plant devoted to medical waste (Sembcorp http://www.sembcorp.com/en/business-on-site-services-solid_waste_management.aspx). </p>
+</div>
+<h3>Safety Requirements for iGEM Participation</h3>
+<div>
+<p>For the fulfillment of requirements for safety from the iGEM foundation, we have submitted the ‘About our lab’ safety forms (https://2015.igem.org/Safety/About_Our_Lab?team_id=1804) and the ‘Final Safety form (Yihan will complete this later to the deadline as currently can’t confirm what we are submitting to parts registry. Just put in first)’ </p>
+<p>We have also performed a check-in (https://2015.igem.org/Safety/Check_In) for the Biobricks Part (Bba_k299812 http://parts.igem.org/wiki/index.php?title=Part:BBa_K299812), which contains the invasin gene from Yersinia pseudotuberculosis and the listerolysin O gene from Listeria monocytogenes. </p>

+<h3>Gold</h3>
+<div>
+  <p><strong>In addition to the Bronze and Silver Medal requirements, your team must convince the judges you have achieved at least two of the following goals:    </strong></p>
+  <p>1. Choose one of these two options: (1) Expand on your silver medal Human Practices activity by demonstrating how you have integrated the investigated issues into the design and/or execution of your project. OR (2) Demonstrate an innovative Human Practices activity that relates to your project (this typically involves educational, public engagement, and/or public perception activities; see the Human Practices Hub for information and examples of innovative activities from previous teams).  </p>
+  <p>2. Help any registered iGEM team from a high-school, different track, another university, or institution in a significant way by, for example, mentoring a new team, characterizing a part, debugging a construct, modeling/simulating their system or helping validate a software/hardware solution to a synbio problem.  </p>
+  <p>3. Improve the function OR characterization of a previously existing BioBrick Part or Device (created by another team, or by your own team in in a previous year of iGEM), and enter this information in the part's page on the Registry. Please see the Registry Contribution help page for help on documenting a contribution to an existing part. This part must not come from your team's 2015 range of part numbers.
+    Demonstrate a functional prototype of your project. Your prototype can derive from a previous project (that was not demonstrated to work) by your team or by another team. Show this system working under real-world conditions that you simulate in the lab. </p>
+</div>
+<h3>Silver</h3>
+<div>
+  <p><strong>In addition to the Bronze Medal requirements, your team must convince the judges you have achieved the following 3 goals:    </strong></p>
+  <p>1. Experimentally validate that at least one new BioBrick Part or Device of your own design and construction works as expected. Document the characterization of this part in the Main Page section of the Registry entry for that Part/Device. This working part must be different from the part you documented in Bronze medal.    </p>
+  <p>2. Submit this new part to the iGEM Parts Registry. This part must be different from the part you documented in Bronze medal. (Submissions must adhere to the iGEM Registry guidelines.)    </p>
+  <p>3. iGEM projects involve important questions beyond the bench, for example relating to (but not limited to) ethics, sustainability, social justice, safety, security, and intellectual property rights. We refer to these activities as Human Practices in iGEM. Demonstrate how your team has identified, investigated and addressed one or more of these issues in the context of your project.</p>
+</div>
+<h3>Bronze</h3>
+<div>
+  <p>1. Register for iGEM, have a great summer, and attend the Giant Jamboree.    </p>
+  <p>2. Complete the Judging form.
+    Create and share a Description of the team's project using the iGEM wiki, and document the team's parts using the Registry of Standard Biological Parts.    </p>
+  <p>3. Present a poster and a talk at the iGEM Jamboree.    </p>
+  <p>4. Create a page on your team wiki with clear attribution of each aspect of your project. This page must clearly attribute work done by the students and distinguish it from work done by others, including host labs, advisors, instructors, sponsors, professional website designers, artists, and commercial services. </p>
+  <p>5. Document at least one new standard BioBrick Part or Device central to your project and submit this part to the iGEM Registry (submissions must adhere to the iGEM Registry guidelines). You may also document a new application of a BioBrick part from a previous iGEM year, adding that documentation to the part's main page. </p>
