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

Preparation Note

1. Suspend 35.6 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 of sterile 1 M magnesium sulfate after autoclaving.

Add 35.6g powder in 1L water. Heat to boiling while stirring to dissolve powder. Autoclave for 15 minutes at 121C to sterilize. Allow to cool slightly before making additions, such as antibiotics (if desired). Pour into petri dishes and allow to solidify.

Protein microarrays provide an efficient way to identify and quantify protein-protein interactions in high throughput. One drawback of this technique is that proteins show a broad range of physicochemical properties and are often difficult to produce recombinantly. To circumvent these

Manipulating and tracking single hepatocyte behavior during mouse liver regeneration by performing hydrodynamic tail vein injection.

STAR protocols, 2(2), 100440-100440 (2021-04-27)

Studies to identify genes relevant to mammalian hepatocyte biology in vivo are largely carried out using germline genetic-engineering approaches, which can be costly and time-consuming. We describe hydrodynamic tail vein injection as an alternative approach to introduce genetic elements into

Quiescence is a fundamental property that maintains hematopoietic stem cell (HSC) potency throughout life. Quiescent HSCs are thought to rely on glycolysis for their energy, but the overall metabolic properties of HSCs remain elusive. Using combined approaches, including single-cell RNA
