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
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)
Features and Benefits
Lennox LB powder with agar provides:
- A budget-friendly alternative to pre-poured plates
- Easy scale-up using larger package sizes
- Standard formulation
Preparation Note
1. Suspend 35 g in 1 L of distilled water.
2. Heat to boiling while stirring to dissolve all ingredients completely.
3. Autoclave for 15 minutes at 121°C.
To prepare Lennox L Agar: Add 1 g glucose and proceed with preparation instructions as above.To prepare the medium of Enquist and Sternberg: Aseptically add 10 ml sterile 1 M magnesium sulfate after autoclaving.
