Experiments

Transformations

BI21 Cells:

  1. Thaw 50 µL vial of BL21 cells on ice
  2. Inoculate 2µL DNA into 50µL BL21 cells
    • incubate on ice for 30 minutes
    • heat shock at 42℃ for 10 seconds
    • incubate on ice for 5m
  3. Inoculate 250µL LB into vial
    • incubate at 37℃ with shaking for 1.5 hours
  4. Plate 1x/9x

JM109 Cells:

  1. Thaw vial of JM109 cells on ice
  2. Label 14 mL Falcon tube & plane on ice
  3. Inoculate 50 µL JM109 cells into Falcon tube
  4. Inoculate 2µL DNA into 50µL JM109 cells
    • incubate on ice for 20m
    • heat shock at 42℃ for 45 seconds
  5. Inoculate 950µL LB into vial
    • incubate at 37℃ with shaking for 1.5 hours
  6. Plate 1x/9x


Electrophoresis/Gel Protocols

1% Agarose Electrophoresis Gel

  1. Add 0.35 g agarose to 35 mL 1x TAE in 100mL conical flask
  2. Heat in microwave for 35 seconds
  3. Swirl and heat in microwave for 25 seconds
  4. Swirl and heat in microwave for 15 seconds
  5. Swirl and heat in microwave for 7 seconds
  6. Swirl and ensure no ‘floaties’
  7. Cool outside of conical flask with water until ‘hand not’
  8. Pour into gel mold and add well comb

Gel Extraction

  1. Use ethanol-wiped scalpel to excise appropriate bands
  2. Mix and incubate at 50°C for 10 min
    • Vortex every 2 mins until gel slice is completely dissolved
  3. Place nucleospin column into 2mL collection tube
    • Add sample
    • Centrifuge at 11,000 xg for 1 minute
    • Discard throughflow and place column back in same tube
  4. Add 700 mL Buffer NT3
    • Centrifuge at 11,000 xg for 1 minute
    • Discard throughflow and place column back in same tube
  5. Repeat step 4
  6. Centrifuge at 11,000 xg for another minute
    • To remove buffer
      • Discard throughflow
      • Centrifuge at 11,00 xg for add minute
      • Place column in a clean, labelled 1.5 mL tube
  7. Add 25 mL prewarmed (50°C) Buffer NE
    • Incubate at 50°C for 5 min
    • Centrifuge at 50 xg for 1 minute
    • Centrifuge at 11,000 xg for 1 minute

Plasmid Transformation Protocol

  1. Aliquot 1 ml media into 1.5 mL tubes
    • Place in 42°C waterbath
  2. Prechill labelled 14 mL round-bottom falcon tubes
    • Add mL cell culture to tube
    • Add appropriate amount of ligase rxh (2-2.5 L)
    • Incubate in nice for 20 minutes
  3. Heat shock cells by placing at 42℃ for 45 seconds in waterbath
    • Place on ice for 2 minutes
  4. Add 950 mL preheated media to each tube
    • Incubate at 37℃ with 215 rpm shaking for 1.5 hr -> 20 minutes

Plating

  1. Plate on LB-antibiotic plates
    • Plate 100 ml for 1x transformation
    • Plate 100 mL 9x centrifuge remaining transformation at 2000 xg for 5 minutes and resuspended pellet in 100 L media

Plates Protocol

  1. Follow LB Agar Recipe
    • Make sure to put stirring bar in water
    • Needed to make into homogenous gel
    • Needs to be sterile
  2. Put into Autoclave
    • Lid should not be too tight
  3. Put in ice bath42°C
    • Cool till not burning hand
    • Put on stirring plate
  4. Put sterilized plates in Lamenia shield
  5. Using micropipette put .5 mL of chlor. And amp. agar solution
    • 1000x dilution
    • Amp. has to be defrosted in dark drawer
