Protein identification

Our full service includes sample preparation, sample analysis and data interpretation. If you want to do the sample preparation or data interpretation yourself, let us know during the project consultation.

The service fees are broken down in the tables below.

To provide high quality protein ID results, we recommend the following:

For gel separated samples:

  • regular or colloidal Coomassie Blue, or Sypro ruby-based stains (preferred method)

  • mass spectrometry compatible silver-stain (acceptable but not recommended for subsequent protein IDs)

For solution-based samples:

  • a SDS-gel image, to allow us to assess the protein complexity, dynamic range, and total amount of proteins in the samples.
