Chloramphenicol
   * Stock concentration - 34mg/ml in 100% Ethanol
   * Aliquots - 1ml
   * Working concentration = 25μ/ml (Stringent), 170μ/ml (relaxed) 

Are stringent and relaxed the wrong way around...?

  • Jason R. Kelly 07:08, 17 January 2008 (CST): I think it's right. Relaxed plasmids are normally higher copy, so you'd expect a higher concentration of antibiotic for them.
