Hanahan's Broth (SOB Medium) was developed by Douglas Hanahan (1983) for the cultivation of competent Escherichia coli cells prior to transformation.

SOB Medium is a nutrient-rich, bacterial growth medium that is used for microbiological culture, generally of E. coli.

When 20 mM (0.36%) D-glucose is added to this nutritionally rich medium it is referred to as SOC (Super Optimal broth with Catabolite repression) Medium. It is used in the final stage of transformation; this allows the E. coli cells to mend the perforations and replicate.
