Media was made, Strains sD001-sD004 were received, inoculated, and put into stock and catalog.

4 strains were received from Jake:

E. coli: BL21 (DE3) ko20 ΔcysI, Δfpr, ΔydbK
E. coli: NEBTurbo zmSIR Chloramphenicol
E. coli: NEBTurbo zmFNR Spectinomycin

Wednesday 3^rd July

Chemically Competent Cells : BL21 (DE3) dCysI dFpr dydbk, NEBturbo stocks

Chemically Competent BL21 (DE3) Cells were made
We grew 5ml of sD001 cells overnight from a single colony. This 5ml was used to innoculate 500ml of LB broth.
Broth was incubated for 1.5h and optical density was read at 0.62 OD600.
Cells were alloquoted into 10 falcon tubes (50ml each) and centrifuged at 4000xg for 20 minutes at 4C.
Supernatant was removed and cells were resuspended in 200ml of Buffer 1 (4x 50ml) and left on ice for 20 minutes.
Cells were centrifuged again for 20 minutes at 4000xg.
Supernatant was removed and cells were resuspended in 12ml Buffer 2.
Cells were alloquoted at 500ul into microcentifuge tubes and frozen at -80C.
Buffer 1: 50mM CaCl2
Buffer 2:

0.53ml 2M CaCl2
2.8ml 60% Glycerol
8.67ml sterile H2O

This is the correct Chemical Competent Cells protocol (Similar to Protocol 2) , that we should have used instead of the one above:

Take a single colony of E. coli cells and inoculate 5ml of LB broth.
Incubate over night at 37C and 200rpm and innoculate about 500ml to 1L sterile LB broth.
DO NOT ADD antibiotics since these cells do not have a plasmid in them.
Work as sterile as possible.
Inoculate about 300-400ml sterile LB broth with 500ul of preculture.
Grow the cells on a shaker at 37C until they reach an OD @ 600nm of 0.3 to 0.4 (1cm pathlength of the cuvette).
Centrifuge at 3000xg for 10 minutes at 4C. Ice down 100mM CaCl2 and 100mM MgCl2 solutions at this point.
Gently resuspend the bacteria pellet on ice in 50ml of ice cold 100mM MgCl2, taking 3-5 minutes for this procedure.
Centrifuge the cell suspension at 3000xg for 10 minutes at 4C.
Resuspend the bacteria pellet on ice 50ml of ice cold 100mM CaCl2, incubate the cells for 10 minutes on ice.
Centrifuge the cell suspension at 3000xg for 10 minutes at 4C and resuspend the cell pellet in 4ml of ice cold, sterile 100mM CaCl2 in 15%(w/v) glycerol.
Dispense in 50uL aliquots and freeze cells at -80C.

Chemically competent cells (NEB Turbo)
Prepared via iGEM chemically competent protocol with following changes.
500ul of preculture used to inoculate 500ml LB broth. Grown at 37C for 3h hours to an OD600 of 0.536.
Cells centrifuged at 3200 rpm on old centrifuge for 10m at 4C. Pellets resuspended in 80ml of CCMB80 buffer.
Incubated on ice for 20m. Centrifuged for 10m at 3200 rpm for 10m at 4C.
Pellets resuspended in 5ml of CCMB80 buffer. Aliquoted into Microcentrifuge tubes and frozen at -80C.

Heat Shock Transformation

Preparation of Agar Plates
LB Agar was melted; 100ml was used to make 8 ampicillin plates,
100ml was used to make 8 spectinomycin plates and the remaining was used to make 20 chloramphenicol plates.
Antibiotic concentrations are: Ampicillin 50ug/ml, Spectinomycin 50ug/ml, Chloramphenicol 34ug/ml.

Heat Shock Transformation
sD001: BL21 (DE3) with deletions, was transformed with the following plasmids and plasmid combinations:

sD001+pD004 ( FNR, Spectinomycin)
sD001+pD005 ( SIR, Fdx, Chloramphenicol)
sD001+pD006 (Sir, Chloramphenicol)

Transformation was done according to protocol 1 with the following specifications:
BL21 (DE3) chemically competent cells were thawed on Ice. 1ul of plasmid DNA was added to a tube of BL21 (DE3) cells.
Cells were incubated on ice for 30 minutes. Cells were transfered to heating block at 42C for 45s.
Cells were returned to ice for 2 minutes. 1ml of LB Broth was added to the cells and they were incubated at 37C for 1h.
Cells were then plated on agar with appropriate antibiotics (specified previously). These transformations worked; single colonies were lifted from plates, entered to catalog and stocked in glycerol stock (protocol 3).
Catalog names:

sD006= sD001+pD004 ( FNR, Spectinomycin)
sD007= sD001+pD005 ( SIR, Fdx, Chloramphenicol)
sD008= sD001+pD006 (Sir, Chloramphenicol)

Planning transformations for the next week

We decided to partly reproduce Figure 3C from: http://www.jbioleng.org/content/5/1/7:

So, we would pursue to grow the following strains on a minimal media M9 plate, supplemented with all amino acids

aside from the sulfur containing ones, and sulfite ans the only sulfur source:

We already thought we have all of the strains we need, however, an overnight culture was launched of a few single colonies from this double plasmid strain (sD001+pD004+pD005, which supposedly had all 3 genes SIR FNR and Fdx) and it didn't grow.

This most likely occurred because the strains didn't have Spec antibiotics resistance, as the other spec resistant strain containing

the FNR gene (pD004), was found not to be resistant as well.

Illustration 1: Strains will be grown on a minimal media M9 plate, supplemented with all amino acids aside from the sulfur containing ones; plates will have increased glucose, and sulfite as the only sulfur source. Growth is expected only for WT and the strain containing all three alternative genes of sulfur reduction.

Therefore, we would re-make:

sD001+pD004+pD005 E.coli:ΔcysI, Δfpr, ΔydbK:: soFD, zmSIR ;Chloramphenicol ,zmFNR; Spectinomycin- with all three genes.
sD001+pD004: E.coli:ΔcysI, Δfpr, ΔydbK:: zmFNR; Spectinomycin

and make

sD001+pD004+pD006 E.coli: ΔcysI, Δfpr, ΔydbK::zmFNR; Spectinomycin, zmSIR; Chloramphenicol

These transformations will be done by using two strains of competent cells prepared using Protocol 2 :

sD001 competent cells were transformed with:
- pD004
- Double transformation: pD005 +pD004
sD007 (sD001+pD005) competent cells were transformed with:
- pD004

Thursday 18^th July

Heat shock Transformation

Transformations made:

sD001+pD004+pD005 E.coli:ΔcysI, Δfpr, ΔydbK:: soFD, zmSIR ;Chloramphenicol ,zmFNR; Spectinomycin- with all three genes

sD001+pD004+pD006 E.coli: ΔcysI, Δfpr, ΔydbK::zmFNR; Spectinomycin, zmSIR; Chloramphenicol

Transformations were made with protocol 1 with the following specifications:
BL21 (DE3) chemically competent cells were thawed on Ice.
2ul of plasmid DNA was added to 20ul of BL21 (DE3) cells. Cells were incubated on ice for 30 minutes.
Cells were transfered to heating block at 42C for 45s. Cells were returned to ice for 2 minutes.
200ul of LB Broth was added to the cells and they were incubated at 37C for 1h.
After incubations cells of each transformation were plated on two plates: one with 5 ul , and the other with 100 ul of the post recovery cells culture.

Transform NEB 5-alpha Competent E. coli cells (provided with the kit) with 2 μl of the assembly reaction, following the transformation protocol.

Transformation (Gibson)
Thaw competent cells on ice.
Add 2 μl of the chilled assembly product to the competent cells. Mix gently by pipetting up and down or by flicking the tube 4–5 times. Do not vortex.
Place the mixture on ice for 30 minutes. Do not mix.
Heat shock at 42°C for 30 seconds. Do not mix.
Transfer tubes to ice for 2 minutes.
Add 950 μl of room-temperature SOC media to the tube.
Incubate the tube at 37°C for 60 minutes. Shake vigorously (250 rpm) or rotate.
Warm selection plates to 37°C.
Spread 100 μl of the cells onto the selection plates. Use Amp plates for positive control sample.
Incubate overnight at 37°C.

Transformation (Gibson, Ligations)
1) Prepare BD tubes with a pipette filled with LB at the interior of each tube (pipette supplied with the electroporation cuvette)

2) Test the purity of the electrocompetent cells.
Add 200 ul of washed cells to a cuvette.

3) Mix the cells and DNA in a cuvette.
200 ul of washed cells with 200 ng of PCR product.
Keep the cuvette on ice until just before the electroporation.

4) Preload a pipette with 1 ml of LB.

5) Pulse the cuvette with voltage.
Dry the electrodes with a kimwipe prior to loading.
Use the EC2 setting.

6) Listen for arcing.
A cracking sound means all the cells are dead.
Note the time constant: 5 is good, 5.8 is great.

7) Immediately recover the cells.
Add the 1 ml of preloaded LB and pipet up and down to mix.
Collect 1 ml of cells, some volume is lost in the cuvette.

8) Incubate 2 h at 37 °C with shaking.

9) Plate 100 ul of recovered cells on selective plates.
Use antibiotic appropriate to the part being integrated.
Let the other 900 ul rest overnight at room temperature.

10) Concentrate and plate the remaining cells
Spin down quickly and resuspend in 100 ul LB before plating.

Transformed cells should be incubated at 37 °C.

Making Electrocompetent Cells

1) Start a liquid culture of cells. NEB turbo
2) dilute the cells 100X.
100 ml LB.
Grow at 30°C for about 90 minutes.
3) Harvest the cells.
When the cells reach an OD600 of between 0.6 and 0.8
Split the culture into 2x 50 ml falcon tubes, on ice.
Centrifuge at 4 °C for 10 min at 4000 rpm.
5) Wash and combine the cells.
Remove the supernatant.
Resuspend the cells in 2x 25 ml of ice cold water.
Combine the volumes in a single 50 ml falcon tube.
6) Wash the cells 2 more times.
Centrifuge at 4 °C for 10 min at 4000 rpm.
Resuspend in 50 ml of ice cold water.
Repeat.
7) Wash and concentrate the cells for electroporation.
Centrifuge at 4 °C for 10 min at 4000 rpm.
Resuspend in 1-2 ml of ice cold water.
We will use 200 ul of washed cells per transformation.

Transformation

4) Preload a pipette with 1 ml of LB.

5) Pulse the cuvette with voltage.
Dry the electrodes with a kimwipe prior to loading.
Use the EC2 setting.

6) Listen for arcing.
A cracking sound means all the cells are dead.
Note the time constant: 5 is good, 5.8 is great.

7) Immediately recover the cells.
Add the 1 ml of preloaded LB and pipet up and down to mix.
Collect 1 ml of cells, some volume is lost in the cuvette.

8) Incubate 2 h at 37 °C with shaking.

9) Plate 10/200 ul of recovered cells on selective plates.
Use antibiotic appropriate to the part being integrated.
Let the other 900 ul rest overnight at room temperature.

10) Concentrate and plate the remaining cells
Spin down quickly and resuspend in 100 ul LB before plating.

Transformed cells should be incubated at 37 °C.

Gel extraction
1. Excise the DNA fragment from the agarose gel with a clean, sharp scalpel. Minimize the size of the gel slice by removing extra agarose.
2. Weigh the gel slice in a colorless tube. Add 3 volumes of Buffer QG to 1 volume of gel (100 mg ~ 100 μl). To help dissolve gel, mix by vortexing the tube every 2–3 min during the incubation.
3. After the gel slice has dissolved completely, check that the color of the mixture is yellow (similar to Buffer QG without dissolved agarose).
4. Add 1 gel volume of isopropanol to the sample and mix (actually only needed for very small products or very big products) 5. To bind DNA, apply the sample to the QIAquick column, and centrifuge for 1 min.
6. Discard flow-through and place QIAquick column back in the same collection tube.
7. To wash, add 0.75 ml of Buffer PE to QIAquick column and centrifuge for 1 min.
8. Discard the flow-through and centrifuge the QIAquick column for an additional 1 min at 17,900 x g (13,000 rpm).
9. Place QIAquick column into a clean 1.5 ml microcentrifuge tube.
10. To elute DNA, add 30 μl elution buffer to the center of the QIAquick membrane, let the column stand for 1 min, and then centrifuge for 1 min.

Electrocompetent cells
1) Start Culture
2) When the cells reach an OD600 of 0.2.
3) Harvest the cells.
When the cells reach an OD600 of between 0.6 and 0.8 (OD: 0,683)
Centrifuge at 4 °C for 10 min at 4000 rpm.
4) Wash and combine the cells.
Remove the supernatant.
Resuspend the cells in 25 ml of ice cold water
5) Wash the cells 2 more times.
Centrifuge at 4 °C for 10 min at 4000 rpm.
Resuspend in 50 ml of ice cold water.
Repeat.
6) Wash and concentrate the cells for electroporation.
Centrifuge at 4 °C for 10 min at 4000 rpm.
Resuspend in 1-2 ml of ice cold water.
We will use 200 ul of washed cells per transformation.

1) Prepare BD tubes with a pipette filled with LB at the interior of each tube (pipette supplied with the electroporation cuvette)

2) Test the purity of the electrocompetent cells.
Add 200 ul of washed cells to a cuvette.

3) Mix the cells and DNA in a cuvette.
200 ul of washed cells with 200 ng of PCR product.
Keep the cuvette on ice until just before the electroporation.

4) Preload a pipette with 1 ml of LB.

5) Pulse the cuvette with voltage.
Dry the electrodes with a kimwipe prior to loading.
Use the EC2 setting.

6) Listen for arcing.
A cracking sound means all the cells are dead.
Note the time constant: 5 is good, 5.8 is great.

7) Immediately recover the cells.
Add the 1 ml of preloaded LB and pipet up and down to mix.
Collect 1 ml of cells, some volume is lost in the cuvette.

8) Incubate 1/2 h at 37 °C with shaking.

9) Plate 10/200 ul of recovered cells on selective plates.
Use antibiotic appropriate to the part being integrated.
Let the other 900 ul rest overnight at room temperature.

10) Concentrate and plate the remaining cells
Spin down quickly and resuspend in 100 ul LB before plating.

Transformed cells should be incubated at 37 °C.
Colonies should appear 24-48 h after plating.

Extraction of Genomic DNA, PCR Reaction and Restreak plates

Protocol: E. coli Colony PCR (pS006’, pS006*, pS013, pS004, pS004*, pS002*)

Extraction of Genomic DNA

1) Pick a single colony into 50 ul of H20.
Fresh colonies (grown that day) work best, but they can also come from 4 C.
Pipet 2ul onto plates to have C1-C8
Pipet 2 ul into 5ml Media with antibiotics to make liquid cultures

2) Boil for 5 minutes.
1.5 ul of this can be used directly for PCR.
Best if used directly, but can also be stored at 4 C for a few days.

PCR Reaction

Keep all the reagents at 4 °C while preparing the mixture.
Pre-heat the thermocycler to 95 °C and transfer your reaction directly from 4 °C.

Infectiveness characterization experiments

The night before: prepare O/N of F+ cells, prepare O/N of phagemid producing cells (in this case : sT007 )
Centrifugate phagemid producing cells
Filter the supernatant 0.45um, stock it at 4°C (it contains the phages)
Dilute 200x MGZ1, F+ from O/N
Wait until OD600 = 0.7
Immediately mix MGZ1 and the supernatant in different proportions

Here we tried 1/1 (vol supernatant/vol cells), 1/10 and 1/100

Plate 100uL of those dilutions on LB-agar, AMP, KAN, AMP+KAN
Incubate O/N
Count colonies
Interpretation: Colonies on AMP: infected by litmus28i
Colonies on KAN: infected by M13K07
Colonies on AMP+KAN: coinfected by litmus28i and M13K07 phagemid producing cells

Results

Conclusions:

Cells that were mixed with 1/1 supernatant didn't survive the excess of antibiotics that were present in the supernatant.
Even at low ratio like 1/100 the infection rate of litmus28i-GFP is about 100%. GFP detection confirmed this result: almost 100% of cells were fluorescent.
Co-infection did occur. It would be interesting to test if those colonies are indeed producing phages.
