Sample Requirements "Bioburden Testing"

Methods are established for “state-of-the-art” chemically defined cell culture media. Due to potential matrix effects verification of sample feasibility might be necessary prior to analysis. Please note that feed media matrix should be considered seperately. If you plan to measure pure feed media, feel free to contact us for more information.

For Spent Media Samples:

 

For Metabolomic Samples:

  • Samples can be cell lysates or supernatants. Please contact us for individual support regarding sample preparation.
  • Please read and sign our sample declaration sheet.
