General description
Lennox LB is a highly-referenced microbial growth medium used for the cultivation of E. coli. This nutrient-rich microbial broth contains peptides, amino acids and carbohydrates in a low-salt formulation.
Application
Luria Broth is used for maintenance and propagation of Escherichia coli. The E. coli grow faster in Luria Broth because the tryptone and yeast supply essential growth factors that the E. coli would otherwise have to synthesize. Luria Broth also contains essential electrolytes for transport and osmotic balance, due to the NaCl component.
It was used for resuspension of T. pyriformis cell fractions in a study of Trimastix fractionation of cellular extracts.

Suitable for non-selective cultivation of E. coli strains for cloning, DNA plasmid production and production of recombinant proteins. Also suitable for selective cultivation when appropriate antibiotics are added, including those that require low-salt conditions, such as Zeocin®.
Features and Benefits
Lennox LB powder provides:
- Convenient small package to eliminate weighing
- Easy scale-up using larger package sizes
- A budget-friendly alternative to liquid
- Standard formulation
