Overview

Protocol for making 20 ml of 1360x (stringent) or 200x (relaxed) stock solution of chloramphenicol. This was adapted from Endy:Preparing_Antibiotic_Stocks. See also Chloramphenicol

CAUTION: Chloramphenicol is a suspected carcinogen. Use gloves, goggles, and the fume hood.

Materials

  1. 200 proof ethanol (100%)
  2. chloramphenicol (BP904-100)

Procedure

  • Fill a 50mL centrifuge tube with 20mL of 200 proof ethanol. (we use a centrifuge tube because it must withstand vigorous vortexing)
  • Weigh out 680 mg chloramphenicol. Insert this into the tube.
  • Vortex the tube vigorously until it is well-mixed.
  • Aliquot the solution into 1.5mL eppendorf tubes. Label each tube. Store them in a labelled bag in the -20C chest freezer in 3007.
