2 - Generic protein purification process


Value proposition / USP:

Proteins that are expressed recombinantly or produced synthetically are often not good enough in functionality and stability. In addition, often-used chromatography-based purification is laborious and expensive. We are able to set up an optimized, robust, patented, generic process for the production, purification, and crystallization of high-grade proteins. In the case of the 20S, 26S/30S and immunoproteasome, it generated large quantities of protein and allowed hundreds of crystals to be grown that routinely diffracted to high resolution. Further tests with HDAC and fatty acid synthase were equally successful.


Business model:

  • Sub-licensing of relevant IP (exclusive / non-exclusive)
  • Knowledge transfer & training
