Opis

Opis ogólny

Hannahan’s Broth (SOB) is a microbial growth medium used for the preparation and transformation of competent cells (E. coli). Casein enzymic hydrolysate and yeast extract supply nitrogenous compounds and growth factors for recombinant Escherichia coli. Potassium chloride and sodium chloride maintain the isotonic condition. Magnesium sulfate is added to the medium as a necessary component for DNA replication.

Zastosowanie

Hanahan′s Broth is recommended for use in cultivation of recombinant strains of Escherichia coli. It is suitable for the preparation of competent E. coli., often with the addition of 0.4% dextrose. It has also been used for the preparation of C. necator H16 competent cells. It is suitable for non-selective cultivation of E. coli strains for cloning, DNA plasmid production and production of recombinant proteins.
