  • Description

    Cycloheximide is a protein synthesis inhibitor in eukaryotic cells and is commonly used to prevent fungal growth. 

    TOKU-E offers three forms of cycloheximide: cycloheximide (C001), cycloheximide solution (C084), and cycloheximide ultrapure (C071). Cycloheximide solution is dissolved in DMSO at 100 mg/mL. Cycloheximide ultrapure is ≥98% pure and is free of toxic isomers that can potentially kill wanted fungi in a selection media. 

    This product is considered a dangerous good. Quantities above 1 g may be subject to additional shipping fees. Please contact us for specific questions.

    Mechanism of Action

    Cycloheximide prevents ribosomal translocation during translation as shown in a yeast model. Effective doses are present at concentrations around 200 µM to inhibit yeast growth.

    • Plant Biology Applications

      Cycloheximide is a frequently used lab reagent to inhibit fungal growth by targeting protein synthesis. In yeast, concentrations of 200 µM have fungicidal effects. (Schneider-Poetsch, 2010).
