Experiments

Describe the research, experiments, and protocols you used in your iGEM project. These should be detailed enough for another team to repeat your experiments.

Please remember to put all characterization and measurement data for your parts on the corresponding Registry part pages.

What should this page contain?
  • Protocols
  • Experiments
  • Documentation of the development of your project
Inspiration

General

Materials:
  • LB Broth, Miller (acumedia)
  • dH2O
  • Stir bar
  • Autoclave
Procedure:
To make 1 L of LB Media:
  • Combine 25 g of LB Broth to a beaker containing a magnetic stir bar.
  • Fill with dH2O up to 1000 mL
  • Mix the solution on a stir plate until consistent throughout
  • Separate the mixture into to 1 L containers, so as to avoid overflow in the autoclave. Ensure the caps of the containers are loosened to allow steam to enter.
  • Autoclave at a liquid cycle for 45 minutes; tighten container caps after the media has cooled to prevent contamination.
Materials
  • LB powder (Various, currently Miller Acumedic)
  • Bacto Agar (BD)
  • dH20
  • Antibiotics
  • Petridishes

Media Preperation
  1. Add dH20 to autoclavable bottle (500mL in 1L bottle)✓
  2. Add LB powder (12.5g for 500mL)✓
  3. Add agar (7.5 for 500mL)✓
  4. Mix using magnetic stir bar or shaking✓
  5. Autoclave for 30 minutes on liquid cycle✓

Plate Preperation
  1. Ensure media is cooled to 50-60°C✓
  2. Add antibiotics to final concentratation✓
  3. Mix using stir bar or shaking✓
  4. Pour plates in biosafety hood, ~20mL in each✓
  5. Let cool with lid askew✓
  6. When cool stack with top down and slide back in petri dish bag✓
  7. Tape and Label✓

  • Oxidized nickel wire + Small ~3 mm rubber stoppers
  • Large metal needles for sampling
  • 3 mL plastic syringe (to be cut to act as housing for a counter-electrode)
  • Small magnetic stir bars
  • Needles and syringes of various size (sterile)
Chemicals:
  • Carbon paste suspended in Xylene
  • M5 Minimal Media (100 Mm Hepes)
  • KCl, crystal
  • dH2O
  • Bacto Agar
  • Vitamins/Minerals
  • 200 mM Lactate
  • Spectinomycin Antibiotic
