M9 Minimal medium salts powder

M9 Minimal Salts are a commonly used base for preparing a defined synthetic medium for the growth of most E. coli host cells. The powder is reconstituted in sterile purified water, (or water with melted purified agar added.) Additional nutrients, such as glucose or other carbon source, casamino acids, vitamins, or antibiotics are added when the solution cools and before plates are poured or media is inoculated with bacteria.

Application Notes

M9 Minimal medium salts are suitable for the preparation of M9 Minimal Medium for use in propagation of E. coli and plasmid amplification. The resulting M9 medium can be used for maintaining positive selection pressure on plasmids coding for genes to produce essential substances such as amino acids and vitamins and for maintenance of F’-containing bacteria strains for M13 propagation.
