Descripción general

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.

Aplicación

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®.

Características y beneficios

Lennox LB EZMix™ powder provides:
  • 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

Componentes

*Note some of the product sizes available are given in liquid measure. This is a powder format product and those sizes reflect the final reconstituted volume.

10g/L Tryptone
5 g/L Yeast Extract
5 g/L NaCl
0.6 g/L inert binder (EZMix formulation only)

Nota de preparación

1. Suspend 20.6 g in 1 L of distilled water.
2. Autoclave for 15 minutes at 121 °C.
To prepare Lennox L Broth: Add 1 g glucose and proceed with preparation instructions as above.
To prepare the medium of Enquist and Sternberg: Aseptically add 10 ml of sterile 1M magnesium sulfate after autoclaving.

Reconstitución

Stir to suspend 20.6g powder in 1L water. Autoclave for 15 minutes at 121°C to sterilize. Allow to cool before making additions, such as antibiotics (if desired).

The Mycobacterium tuberculosis rmlC gene encodes dTDP-4-keto-6-deoxyglucose epimerase, the third enzyme in the M. tuberculosis dTDP-L-rhamnose pathway which is essential for mycobacterial cell-wall synthesis.
