Simple Western Assays

The Simple Western™
Gel-free. Blot-free. Hands-free.

ProteinSimple dPC Fractionator for Simplified Protein Sample Fractionation
A Simple Western is the Western you know well, only simplified. It is not a workaround to the existing process, a Western-like substitute, or a partial solution. It's the real thing, completely reinvented. We at ProteinSimple think that's something to get excited about!

Learn about the new Simon™ System!


  • Get your time back. Load your samples in Simon, press start and go enjoy your new hands-free time. Come back a few hours later to fully analyzed results.
  • Get more consistency. People introduce variability—we are human after all. Simple Westerns are fully automated by Simon, so they just give you more reproducible data.
  • Get truly quantitative. Since blot transfer of proteins isn't needed, you can get straight to real, quantitative results.
