General description

Lennox LB is a highly-referenced microbial growth medium used for the cultivation of Escherichia coli. This nutrient-rich microbial broth contains peptides, amino acids, water-soluble vitamins and carbohydrates in a low-salt formulation. The addition of agar provides a solid medium for microbial growth.


Suitable for non-selective cultivation of E. coli strains for cloning, DNA plasmid production and production of recombinant proteins.
LB Agar Plates has been used:
  • to culture bacteria like, Escherichia coli strain INV- α and methicillin-susceptible Staphylococcus aureus
  • to culture numerous bacteria and is used in strain storage method
  • to analyse the egestion of midgut microbes during sand fly bites

Features and Benefits

Lennox LB Agar plates provide:
  • Convenient, ready-to-use 10cm format
  • Standard formulation
