M9 Minimal Salts Base, 5x Size:250g Used as a selective markerM9 Minimal Salts Base, 5x is used in preparing M9 Minimal medium used for the cultivation and maintenance of E. coli in molecular biology. M9 is a chemical defined minimal medium supporting the growth of "wild type" strains of E. coli. The medium can be supplemented with specific amino acids or other required nutrients allowing for selection of specific auxotrophs. Glucose may be added as a source of carbohydrate. Nitrogen is provided by ammonium
