Recipes used in the lab

LB Broth

  • Bacto-tryptone: 10 g/L
  • Yeast extract: 5 g/L
  • NaCl 5 g/L

Adjust pH to 7,4 with NaOH, autoclave.

LA

  • Dissolve LB
  • Add agar, 15 g/L

Adjust pH to 7,4 with NaOH, autoclave.

SOC:

  • Bacto-tryptone: 20 g/L
  • Yeast extract: 5 g/L
  • NaCl 0,5 g/L
  • 10 mL 250 mM KCl (25mM) → 0,186 g / 10mL H20
  • 5 mL 2M MgCl2 (10mM) → 0,952 g / 5mL

Autoclave, cool, then add:

  • 20 mL 1M sterile-filtered glucose (20mM)

Ampicillin-plates:

Use stock 200 mg/mL. → 100µg/mL in liquid agar. I.E. 250 µL stock in 500 mL agar. Add when cool enough to pour.


Spectinomycin-plates:

Use stock 100 mg/mL. → 100µg/mL in liquid agar. I.E. 500 µL stock in 500 mL agar. Add when cool enough to pour.


Ampicillin-IPTG plates:

Ampicillin 100 µg / mL (500 µL amp stock (200 mg/mL) in 500 mL agar) IPTG 0,1 mM ( 63,5 µL IPTG stock (0,8 M))

Protocols

Resuspending DNA from registry-parts:

  • Poke a hole in foil of corresponding well
  • Resuspend DNA in 10 µL dH2O (pipette up and down a few times)
  • Wait 5 minutes.
  • Transfer the resuspended DNA to pCR tube and store in -20C.


==Transforming competent cells:=0

  • Thaw competent cells on ice
  • Mix with 2 µL plasmid DNA
  • Incubate on ice 30 minutes
  • Heat-shock cells 45 seconds in 42C water-bath.
  • Incubate 5 minutes on ice
  • Add 200 µL SOC
  • Incubate the Eppendorf tubes in Erlenmeyer flask 37C shaking incubator for 2 hours
  • Plate 50 µl and 200 µl of the transformation onto the dishes, and spread.
  • Incubate ON in 37C
