Week 13
23rd July - 29th July
Cloning
- pETDuet-1 and pRSFDuet-1 plasmids were linearised.
- cPCR was performed on IaaH-SpyT. Unsuccessful PCR so nothing was grown up.

Week 14
30th July - 5th August
Protein
- The total cell protein was extracted and products were treated with BugBuster reagent. An SDS-Page gel and Western Blot was ran, however no results were obtained from these experiments. The MES buffer precipitated in the fridge.

Parts
- Double digested aPFD-SpyC and bPFD-SnoopC cloned into pET-Duet plasmids. Also digested linear pSB1C3 backbone provided by iGEM.
- We attempted to gel extract the digested inserts using a Qiagen kit however the yield was very low so we did not proceed with ligation.
Week 16
13th August - 19th August
Cloning
- mCerulean-SnpT and mVenus-SpyT plasmids were sent for sequencing.
- Another attempt was made to clone IaaH-SpyT into pRSFDuet-1. Gibson assembly was performed and the products were transformed into cells.
- cPCR was performed (24 reactions) and successful transformants were grown up.
Protein
- An attempt was made to transform and express mVenus and mCerulean 3. The cultures were lysed with BugBuster and a gel was ran on the products. We were unable to obtain expression from either parts.
- The constitutive BioBrick parts with IaaM and IaaH under the same promoter were expressed.
- Large scale expressions of aPFD, bPFD and Kinase (control) were purified, however we were unable to obtain any positive results from this experiment.
Plants
- Prepared ½ MS media with 1% sucrose. Surface sterilised Arabidopsis thalianaseeds added to 250ml of media and stored at 4C to stratify for 3 days. Remaining 250ml media prepared with 1% agar, square plates prepared.
Enzyme Assays
- Another Salkowski standard curve was produced. Dilutions were done in 5% EtOH.
Week 17
20th August - 26th August
Cloning
- Overnight cultures were miniprepped and digested. Gel was ran to check for the presence of IaaH-SpyT insert.
Protein
- All of the cloned plasmids were transformed into T7 and commercial Lemo cells. Glycerol stocks were made for all the parts, and were grown up and induced with IPTG. There was a lack of difference between induced and non induced cultures.
Plants
- Liquid culture removed from fridge, seed left illuminated at room temperature to germinate.
- 1L of 1/2 MS (1% sucrose, 1% agar) autoclaved however autoclave experienced error mid-run. Once media was able to be collected it had gone bad.
- 10mM filter sterilised IAA stock prepared.
Week 18
27th August - 2nd September
Cloning
- IaaH-SpyT plasmids were sent for sequencing.
- We experienced difficulties in protein expression, which may be due to the presence of the iGEM restriction sites preventing successful translation.
- Original DNA constructs were PCR modified with primers that cut out the iGEM prefix and suffix.
Protein
- His-mCerulean3 and His-mVenus constructs from Dr Dominic Glovers lab, His-mCerulean3-SnpT and Iaa BioBrick parts were grown up and expressed, however expression failed. This was reattempted, however results did not change.
Enzyme Assays
- HPLC standards made - Trp, IAA, IAM.
Week 19
3rd September - 9th September
Cloning
- All modified DNA constructs were cloned into corresponding plasmids and transformed into cells.
- cPCR yielded unsuccessful transformation results.
- We attempted to clone modified aPFD and bPFD into pETDUet-1. After transformation, cPCR was performed; however we were unable to detect successful transformants.
- Plasmids were PCR linearised according to protocol.
Protein
- mVenus and mCerulean3 were successfully expressed and purified.
- Another attempt was made to express aPFD, bPFD, mCerulean3 and mVenus, however there was no expression when the products were ran on an SDS page gel.
Week 20
10th September - 16th September
Cloning
- Another attempt was made in cloning aPFD and bPDS into pETDuet-1. No colonies were formed after transformation.
- Another attempt was made using commercial cells from NEB, which yielded several colonies on both plates.
- cPCR results did not yield positive results.
Protein
- The columns were cleaned.
- Another attempt was made to express IaaM, aPFD-SpyC and bPFD-SnpC, mVenus (positive control). Unfortunately, expression was not achieved.
Parts
- Phusion PCR amplification of aPFD-SpyC, bPFD-SnoopC and IaaM-SnoopT Gblocks (provided by IDT) performed.
- However primers were diluted to 100uM rather than 10uM so the PCR amplification was unsuccessful. Performed PCR amplification of Gblocks again, however extra bands on gel indicated non-specific binding of primers. We decided to generate inserts by restriction enzyme digest of already cloned pET-Duet and pRSF plasmids in future attempts.
Week 21
17th September - 23rd September
Cloning
- We made a decision to switch plasmid vectors for our cloning experiments, using pET-19b instead of pETDuet-1/pRSFDuet-1. DNA constructs were PCR amplified using a new set of primers, which would allow the inserts to be cloned into the new vector.
Protein
- An attempt was made to express aPFD and bPFD, however no expression was achieved.
- The constitutive IaaM and IaaH BioBrick was expressed.
- Waiting for the DNA constructs to be cloned into pET-19b plasmid vector.
Plants
- As an MS media alternative, water agar plates prepared with boiled tap water (tap water to utilise trace minerals, boiled to remove chlorine) and 1% agar.
- Water agar plates were poured out with varying concentrations of IAA and stored at -20 degrees.
Parts
- Double digest of aPFD-SpyC, bPFD-SnoopC and IaaM-Snoop T inserts and linearised pSB1C3 backbone vector with EcoRI-HF and PstI. After digest confirmation via an agarose gel, inserts were ligated with the pSB1C3 vector overnight.
- Ligations were transformed into DH5a cells. Transformation using our own attempts to make competent cells failed so were repeated with commercial competent cells.
- Following cPCR, successful ligations were grown up overnight and miniprepped. Following a diagnostic digest and gel, plasmids with the right insert size were sent for sequencing.

- Overnight Dh5a E. coli cultures containing putative pSB1C3 plasmid containing IaaH-SpyT were miniprepped and verified with diagnostic double digest and gel. Subsequently aPFD, bPFD and IaaH-SpyT in pSB1C3 constructs were sent for sequencing. Sequencing results confirmed successful cloning of aPFD, bPFD and IaaH-SpyT into pSB1C3 vector.
- All BioBrick parts dried down in iGEM provided submission plate overnight in drying oven, Sealed with foil and sent to iGEM registry. Final parts sent for submission: aPFD, bPFD, aPFD-SpyC, bPFD-SnoopC, IaaH-SpyT, IaaM-SnoopT.
Enzyme Assays
- Attempt to do salkowski with enzyme.
- A final attempt was made to perform the Salkowski assay.
Week 25
15th October - 21st October
Cloning
- Final gel depicting all 8 digested pETDuet-1 and pRSFDuet-1 plasmids was ran.
Protein
- Final TEM imaging by Dr Daniel Winter was performed.
Parts
- Double digest of all plasmid samples sent for submission performed and run on final gel to create image for wiki.
