summary : SOB Broth, as a rich medium, is used for the cultivation strains of E.coli. By placing the bacterium in this rich medium, perforations are being created in the bacterial cell wall. Thus, they are being prepared for the introduction of foreign DNA into the cell, and to help survive this process, they are placed into this rich, isotonic environment.

reactivity : Used for maintenance and propagation of E.coli. Microbiologicaly tested.

component : Tryptone 20.0 g; Yeast extract 5.0 g; Sodium chloride 0.5 g. MgSO4×7H2O 5.0g. pH(25°C):7.0~7.4.
