500 mL:

  • Tryptone 2.5 g
  • Yeast extract 1.25 g
  • Glucose 0.5 g
  • NaCl 4.25 g
  • Agar 7.5 g
  • dH2O 500 ml


Mix all ingredients in a 1 litre bottle or flask, cover and autoclave. Label caps with “TNA” to avoid confusion. Immediately after autoclaving, swirl media to dissolve the melted agar. Tighten caps and place bottles in the water bath. Pour plates when the agar temperature is 50-60 ºC.
