คำอธิบาย

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, water-soluble vitamins, and carbohydrates in a low-salt formulation. The addition of agar provides a solid medium for microbial growth.

Application

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 EZMix powder with agar provides:

• A budget-friendly alternative to pre-poured plates
• Granulated, dust-free format for safer handling and faster mixing
• Convenient small package to eliminate weighing
• Easy scale-up using larger package sizes
• Standard formulation
