Recipes Luria Broth (LB) (500 mL): This recipe will make 500 mL of LB media.
Weigh ingredients below and add to 500 mL of distilled water in a bottle: 5 g Tryptone 2.5 g Yeast extract 5 g NaCl 500 mL H2O Cap bottle, but do not tighten. Autoclave using liquid cycle. Tighten lid and store at room temperature. Luria agar plates (50): This recipe will make about 50 plates (100 mm diameter).
Weigh ingredients below and add to 1L of distilled water in a 2L flask: 10 g Tryptone 5 g Yeast extract 10 g NaCl 15 g Agar 1 L H2O Cover flask tightly with foil. Autoclave using liquid cycle, then cool to 55 o C. Add appropriate volume of antibiotic. (For example, add 1 mL of a 100 mg/mL ampicillin stock to obtain a final concentration of 100 μg/mL). Pour a thin layer of LB agar into each petri dish (about 20 mL), and cover with lid immediately. Let plates cool for a few hours or overnight. Store plates in plastic bag at 4 o C.
