Revision as of 03:47, 2 November 2017
Safety
Safety is the number one priority
Preparing stocks, plates, cell cultures, etc.
Week 1, day 1 (26/06)
- Prepared wash bottles of 70% Ethanol
- Made 4x500mL LB media
- 2 with agar for plating
- 2 without agar for preparing overnight cultures
- Made chloramphenicol (CAM) stocks
- Plated out LB + agar onto sterile plates with CAM
Week 1, day 2 (27/06)
- Made 10mL 0.2M acetic acid/1M NaOH
- Prepared 50mL of RF1/RF2 buffer (to make RbCl competent cells)
- Streaked 4 plates (stored in 4°C):
- MG1655ΔLacI onto 2 LB and 1 LB+CAM plates
- DH10β onto 1 LB plate
Week 1, day 3 (28/06)
Streaked 2 LB plates: MG1655ΔLacI & DH10β to replace Tuesday’s plates (because they over-grew)
- New plates put into 37°C incubator overnight, backup plates placed into 4°C fridge
Prepared 5mL LB cultures and placed in overnight shaker of:
- MG1655ΔLacI
- DH10β
Week 1, day 4 (29/06)
- Prepared SOC medium
- Cultured DH10β cells in baffled flasks until OD reached 0.4-0.55
Week 1, day 5 (30/06)
- Plated DH10β cells and incubated at 37°C overnight
Week 1, day 6 (31/06)
- Checked on plated cells from 30/06:
“06-31 plate 1.jpg”
“06-31 plate 2.jpg”
“06-31 plate 3.jpg”
“06-31 plate 4.jpg”
“06-31 plate 5.jpg”
“06-31 plate 6.jpg”
“06-31 plate 7.jpg”
“06-31 plate 8.jpg”
“06-31 plate 9.jpg”
“06-31 plate 10.jpg”
“06-31 plate 11.jpg”
Week 3, day 1 (10/07)
- Made and autoclaved LB and LB+CAM liquid.
- Poured 13 LB plates.
- LB+CAM plates were unsuccessful since incorrect amount of CAM was added (12.5g instead of 12.5mg).
Week 3, day 2 (11/07)
- Made LB+CAM plates
- Plated and spread 50µL and 100µL DH5α cells onto LB agar plates using sterile loops.
- Placed in overnight incubator
Week 3, day 3 (12/07)
-Checked on DH5α plates from the incubator.
“07-12 plates.jpg”
Week 3, day 4 (13/07)
- KAN and CAM antibiotic stocks
- 500mL each of LB+CAM and LB+KAN
- 500mL 1X TAE buffer from 50X TAE buffer and MilliQ water
- Prepared overnight culture of one DH5α colony in 5mL LB at 37°C.
Week 3, day 5 (14/07)
- Checked on DH5α culture
- Initial OD600 was 0.011, so waited 110min for optimal OD600
- Moved culture to ice once OD600 reached 0.466
- Made DH5α stocks stored in -80°C, competence to be tested on Monday using iGEM competence cell test kit.
Week 4, day 1 (17/07)
- Plated transformed cells.
- Spread the DH5α cells onto 4 LB+CAM plates, each containing 100µL of the 100pg/µL, 50pg/µL, 10pg/µL, and 0pg/µL cells.
- Spread the DH10β cells onto two LB+KAN plates, both containing 100µL of the control and either 100µL or 50µL of the pKDL071 cells
- Incubated the plates at 37°C overnight.
Week 4, day 2 (18/07)
- Made LB media
- Made LB+CAM plates
- Checked on 17/07 transformed cells and moved them to the 4°C fridge.
- Confirmed DH5α cells were competent
- Note: LB+CAM plates made on 13/07 may have been made with too much CAM (1250µL CAM to 500mL LB). This may explain why there were so few colonies from 17/07 transformation of DH5α + RFP/pSB1C3.
“07-18 plate 1.jpg”
“07-18 plate 2.jpg”
“07-18 plate 3.jpg”
“07-18 plate 4.jpg”
- Obtained single colonies from transformed DH5α and DH10β plates from 17/07 and made overnight 37°C colonies.
- The DH5α was placed in the 5mL of LB+CAM (5µL of stock CAM added to 5mL LB).
- The DH10β was placed in 5mL of LB+KAN (25µL of stock KAN added to 5mL of LB).
Week 4, day 3 (19/07)
- Examined plates from 18/07
- Most plates had no cells likely due to the high CAM concentration (2.5x working concentration).
“07-19 plates.jpg”

- Transformed DH5α cells using iGEM competence cell test kit with RFP/pSB1C3 at concentrations 100pg/µL, 50pg/µL, 10pg/µL, and 0pg/µL (control)
- Plated the cells onto 4 LB+CAM plates, each containing 100µL of the 100pg/µL, 50pg/µL, 10pg/µL, and 0pg/µL cells.
- Incubated the plates at 37°C overnight.
Week 4, day 2 (18/07)

- Confirmed DH5α cells were competent
- Note: LB+CAM plates made on 13/07 may have been made with too much CAM (1250µL CAM to 500mL LB). This may explain why there were so few colonies from 17/07 transformation of DH5α + RFP/pSB1C3.

- Made 9 tubes: 8 GFP samples and one no plasmid control (labelled 20B, 20D, 20F, 20H, 20J, 20L, 20N, and 20P, respectively).
- Originally, the goal was to make 17 tubes for two transformations (8 samples x 2 + 1 no plasmid control), however, there were not enough cells to to make a second set (missing second set of 20L and 20B).
- Spread 100µL of transformed bacteria on LB+CAM plates to incubate and dry overnight at 37°C.
Week 4, day 3 (19/07)

- GFP: Literature said the maximum exictation wavelength is 395 nm, the maximum emission wavelength is 509 nm
- We measured maximum exication: 390 nm, maximum emission: 400-750 nm.
- YFP: Literature said the maximum excitation wavelength is 512 nm, the maximum emission wavelength is 529 nm.
- Note: No negative control was measured so data can’t be normalized.
- GFP: Literature said the maximum exictation wavelength is 395 nm, the maximum emission wavelength is 509 nm
Week 6, day 2 (01/08)
- Measured the emission spectra of GFP samples 20B, 20D, and 20F with the plate reader

- Excitation range of 488 nm - 501 nm
- Emission maximum at 511 nm
- At a 395 nm excitation wavelength, this GFP mutant emits 0.2x the intensity of wild type GFP. However, at a excitation wavelength of 488 nm, the emission intensity is 21x that of wild type GFP.
- The emission spectra was tested using samples 20B (positive control), 20D (negative control), and 20F from glycerol aliquots.

- Prepared master mix for Q5 HF PCR reactions (with 50µL 3% DMSO). Template DNA is included in 6 tubes with 1 control without template DNA.
- One template DNA tube only contains 25 uL, possibly due to pippetting error
- Note: prepare a master mix of 8 reactions of 50 μL, instead of 7.1 reactions, to accommodate pippeting errors).
- One template DNA tube only contains 25 uL, possibly due to pippetting error
- Ran PCR. Tubes were meant to be optimized through a temperature gradient, but were placed incorrectly in the PCR machine, so they were run all at the same temperature.
- Ran a gel electrophoresis of psB1C3 backbone PCR. The gel was not successful. (Life: What a cruel mistress)
- Note: Gel was made with 15 wells - too small for 10µl samples (15 wells should use ~6-8µl).
“07-12 gel of PCR results.jpg”
Week 3, day 4 (13/07)
Performed Q5 HF PCR to amplify pSB1C3 backbone
- Prepared same master master mixes as calculated 12/07 for 6 samples with template DNA and one control without template DNA

- Control was tested at 70.1°C
- Performed gel electrophoresis of Q5 PCR samples, along with EcoRI digested pSB1C3 with RFP control
“07-13 gel of PCR results.jpeg”
- Advisor suggested results may be due to primer dimerization, possibly because of high primer Tm
- Planned to redesign primers to reduce this problem by removing base pairs from the 3’ binding up to ~15bp homology between primers and backbone
- Aiming for Tm of ~68°C
Week 3, day 5 (14/07)
Redesigned primers based on suggestions from 13/07 to have lower Tm

“07-14 new reverse primer (pKDL071).jpg”
“07-14 new forward and reverse primers (pSB1C3).jpg”
The Q5 polymerase used in previous PCRs is very bubbly which could have been a source of error, so instead we performed 2-step NEB Phusion HF PCR of pSB1C3 with RFP construct
- Used primers from 2016 and 2017 to compare results
- Tubes were labelled 16.1-16.5 (for 2016 primers) and 17.1-17.5 (for 2017 primers)
- Controls without DNA template were labelled NTC (no template control)
- Ran the samples on a temperature gradient to determine the optimal PCR settings

- For self-dimer analysis, click on ‘Self-Dimer’ to bring up a new window with each possible self-dimer your oligo can form. For each diagram you will be able to see the calculated delta G value for this secondary structure. If you have a strong delta G (-9kcal/mol or more negative) this oligo could be problematic.
