Application
M9 Broth is used as a microbiological growth media and for the preparation of phage and plasmid DNA using E. coli K12 strains, acc. to Miller (1987).
Preparation Note
Dissolve 10.5 g in 1 litre distilled water and adjust the pH to 7.4. Sterilize by autoclaving at 121°C for 15 minutes. Add 2 ml 1 M magnesium sulfate (Cat. No. 63133; filter sterilized) and 20 ml of 20% solution from a carbon source (such as glucose; Cat. No. 49140)
