Growth in Bacteria

  • Bacterial Resistance(s)
    Ampicillin, 100 μg/mL
  • Growth Temperature
  • Growth Strain(s)
    this strain
  • Growth instructions
    Growth above 34 C is not recommended, since growth at elevated temperatures leads to leaky expression of toxic proteins from the lambda prophage. A lambda- version will be deposited at addgene soon.
