4-1 Miniprep

Minipreps were performed using FastGene™Plasmid Mini Kit according to the manufacturer's protocols.

4-2 Gel Extraction and PCR purification

Gel Extraction was performed using FastGene™Gel/PCR Extraction Kit according to the manufacturer's protocols.

4-3 Restriction Enzyme Digestion

Restriction enzyme treatment was performed using Q5 High-Fidelity 2x master mix according to the respective manufacturer's protocols.

4-4 Ligation

Ligation was performed using Takara Bio's Ligation High Ver.2 according to the manufacturer's.

4-5 Transformation

1.Thaw competent cells on ice
2.Add DNA sample (2.5μl) to competent cells. leave them on ice for 15 minutes
3.Keep them in heating block for 45 seconds, then cool on ice for 2 minutes
4.Add 90μl SOC liquid culture medium, then incubate for 45 minutes at 37℃
5.Seed cells onto LB+antibiotics agar plate. Incubate for 24 hours at 37℃

4-6 PCR

PCR was performed using Q5 High-Fidelity 2x master mix according to the manufacturer's protocols.

4-7 Sequencing

We outsourced the sequencing to Macrogen

4-8 Western blotting

1.Apply sample to SDS-PAGE minigel (BIOCRAFT 15%).
2.Soak the gel in transfer buffer.
3.Soak PVDF membrane in 100% methanol for 30 sec.
4.Soak PVDF membrane and filter paper in transfer buffer, leave for 5 min.
5.Set filter paper, membrane, gels, filter paper in this order to semidry transfer from anode to cathode.
6.Transfer the proteins from the gel to the membrane with 100 mA for 1 h.
7.Soak membrane in blocking buffer (dilution of 5 g ECL Blocking reagent by 100ml of TBST) for 1 h.
8.Wash for 5 min 3 times with TBST.
9.Apply 1' antibody (dilution of 10 μl of 1’antibody by 10ml of Blocking buffer) and shake for 1 h.
10.Wash for 5 min 3 times with TBST.
11.Apply 2' antibody (dilution of 4μl of 2’antibody by 10ml of Blocking buffer) and shake for 1 h.
12.Wash for 5 min 3 times with TBST.
13.Drain excess wash buffer from the washed membrane and place on flat surface, protein side up.
14.Add detection reagent onto the membrane, covering all of the membrane.
15.Incubate for 5 minutes at room temperature.
16.Drain off excess detection reagent by dabbing with Kimwipe.
17.Place the sample in the CCD camera compartment and record the images.

4-9 Overnight-Culture

1.Prepare LB media by resolving 5g Bacto Tryptone, 1.25g Bacto-yeast extract and 1.25g NaCl in 500ml of milliQ and autoclave it.
2.Transfer 7ml of LB into a culture tube and add the respective antibiotic stock solutions.
3.Inoculate the culture by picking a single colony with a pipet tip and tipping it into the medium.
4.Shake the culture at 37℃ at 180 rpm for 14-16h.
5.Isolate plasmids or use the culture for further experiments.

4-10 Plates

1.Rinse the graduated cylinder with distilled water and add 500 ml of milliQ.
2. Transfer 1. to the flask.
3. Place the following in the flask of 2.
・Bacto Tryptone 5 g
・Bacto yeast extract 2.5 g
・NaCl 2.5g
・Agar 7.5 g
4. After mixing thoroughly, autoclave it after covering with aluminum foil.
5. Add the respective antibiotics.
6. Cool until it gets moderately warm to the touch.
7. Put in a container and fix the lid with the tape after the medium solidifies.
