General description

Miller’s LB is a highly-referenced microbial growth medium used for the cultivation of E. coli. This nutrient-rich microbial broth contains peptides, amino acids, water-soluble vitamins, and carbohydrates. It enables fast growth, improves growth yields for various bacterial species, and can retain the hydrophilic behavior of samples for longer periods.

Application

LBBroth (Miller) is suitable for:

  • non-selective cultivation of E. coli strains for cloning, DNA plasmid production and production of recombinant proteins.
  • selective cultivation when appropriate antibiotics are added.
  • the cultivation of E-coli cells for anti-bacterial assays.

Features and Benefits

Miller′s LB liquid provides:
  • Filter-sterilized, ready-to-use format
  • Convenient package size
  • Standard formulation

Components
