Description
Formulation
Common Applications
Storage

SOB Broth Medium is a nutrient-rich broth used for the cultivation and recovery of E. coli cells, including during competent cell preparation and transformation workflows.

The formulation provides peptides, vitamins, and defined levels of sodium, potassium, and magnesium ions appropriate for growth and handling of E. coli. No antibiotics or glucose are included; glucose may be added after sterilization to prepare SOC Broth.

  • 2.0% Tryptone
  • 0.5% Yeast Extract
  • 10.0mM Sodium Chloride
  • 2.5mM Potassium Chloride
  • 10.0mM Magnesium Chloride
  • 10.0mM Magnesium Sulfate
  • Cultivation of Escherichia coli: Rich medium for robust growth of E. coli strains, leveraging 2.0% Tryptone and 0.5% Yeast Extract with Mg2+ supplementation.

  • Transformation Recovery: Outgrowth medium after chemical transformation or electroporation; often used prior to SOC (SOB + glucose) for maximal recovery.

  • High-Efficiency Cloning: Supports plasmid cloning workflows and library construction by promoting healthy E. coli outgrowth post-DNA uptake.

  • Preparation of Competent Cells: Used in workflows preparing chemically competent E. coli by providing optimal NaCl/KCl and Mg2+ conditions during handling and outgrowth.

  • Protein Expression Starter Cultures: Enables reliable inoculation and amplification of E. coli starter cultures prior to induction.

  • Phage Workflows: Suitable for M13/phage display amplification in E. coli hosts due to Mg2+-rich formulation.

  • Plasmid Propagation: Enhances yield and stability of plasmid-bearing E. coli in liquid culture with added antibiotics as needed.

  • General Bacterial Expansion: Routine expansion and maintenance of laboratory E. coli strains under defined ionic conditions (10.0 mM NaCl, 2.5 mM KCl, 10.0 mM MgCl2, 10.0 mM MgSO4).
