LB 琼脂

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.

LB Broth with agar (Lennox) has been used for:

• the transformation of competent E. coli cells
• to cultivate Ecc-15 bacteria
• embedding scaffold containing tissue derived from induced pluripotent stem cells (iPSCs)
• transmission electron microscopy (TEM) and immunohistochemistry (IHC)

It is 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^®.

Lennox LB powder with agar provides:

• A budget-friendly alternative to pre-poured plates
• Easy scale-up using larger package sizes
• Standard formulation
