General description

The Protease Inhibitor Cocktail for fungal and yeast extracts is a mixture of protease inhibitors in DMSO solution. The cocktail has been optimized and tested for use on fungal and yeast samples, specifically on Saccharomyces cerevisiae cells. One mL of the cocktail is recommended for the inhibition of proteases extracted from 20 g of yeast.


Inhibits serine, cysteine, aspartic, and metalloproteases.


Protease Inhibitor Cocktail has been used as a component in:
  • FA buffer to wash spheroplasts to obtain an average DNA fragment size for chromatin immunoprecipitation (chip)
  • potassium phosphate buffer (pbs) to digest chitin
  • extraction buffer for grinding powdered mycelia for co-immunoprecipitation analysis

Features and Benefits

  • Broad specificity: inhibits a wide range of proteases, providing comprehensive protection to fungal and yeast extracts.
  • Tested on Saccharomyces cerevisiae cells: the cocktail has been optimized for use on this commonly studied yeast strain.
  • Convenient packaging: available in a 1 or 5 mL glass bottle for easy handling and storage.
  • Ready-to-use solution: the cocktail is supplied in DMSO solution for immediate use in protease inhibition assays.
  • Effective inhibition: each component in the cocktail has been carefully selected for its specific inhibitory properties, ensuring reliable and consistent results.
