General description

M9 minimal media is a highly-referenced microbial growth medium used for the cultivation of E. coli. This buffered minimal microbial medium contains only salts and nitrogen, so it is traditionally supplemented with glucose, amino acids and vitamins as needed.

Application

M9 Minimal Salts, 5X is suitable for non-selective cultivation of Escherichia coli strains for cloning, DNA plasmid production and production of recombinant proteins. It is also suitable for selective cultivation when appropriate antibiotics are added.
