General description
Dehydrated Luria-Bertani (LB) broth is called the Lennox LB, which has amino acids as carbon source.
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
LB Broth (Lennox) has been used for culturing Escherichia coli and bacterial artificial chromosomes (BACs).
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 tablets provide:
- Convenient small package to eliminate weighing
- Fast preparation – no stirring required
Preparation Note
Add each 1.1g tablet in 48.3mL water (no stirring required). Autoclave for 20 minutes at 121C to sterilize. Allow to cool before making additions, such as antibiotics (if desired).
