Innovative platform to transform drug discovery

  • Any Application

    We can produce targets for any drug development application with rapid turnaround and scalable yields.

  • Native Accuracy

    Active, full-length proteins from human cells with correct post-translational modifications. No workarounds.

  • Reliable Performance

    Our capability to produce the most challenging targets and antigens allows us to pursue the undruggable.

Biology Engineered

ExcepGen’s proprietary technology enables a high yield of proteins that have historically been difficult — or impossible — to produce.

The technology was developed by ExcepGen co-founders Dr. Thomas Folliard and Dr. Barbara Mertins, two scientists with a background in biochemistry and structural biology.
