Product Overview

Terrific Broth is a highly enriched medium developed by Tartoff and Hobbs to improve yield in plasmid bearing Escherichia coli. Recombinan starins have an extended growth phase in the medium. The addition of extra Tryptone and Yeast Extract in the medium allows higher plasmid yield per volume. Glycerol is used as a carbohydrate source in this formulation. Unlike glucose, glycerol is not fermented to acetic acid. Terrific Broth is used with Glycerol in cultivating recombinant strains of Escherichia coli. (Alpha Biosciences # T20-114M-2Kg)
