Preparation

  1. Prepare the LB base from 10 g/L Bacto Tryptone (Difco), 5 g/L yeast extract, 5 g/L NaCl, 1000 ml/L distilled water, and 15 g/L agar if needed.
  2. Sterilize the 50 mg/ml ampicillin, 10 mg/ml cefpodoxime, and 50 mg/ml kanamycin stocks separately by filtration.
  3. Add 1.0 ml/L each filter-sterilized Ampicillin solution (50 mg/ml), Cefpodoxime solution (10 mg/ml), and Kanamycin solution (50 mg/ml) to the LB base.
