We produce complex human proteins at scale, quickly.

Protein production without compromise

Native Accuracy

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

Scalable production to meet your research needs, with 70% greater sensitivity than conventional methods.
Fast Turnaround

From amino acid sequence to finished product in 8 weeks. No DNA or virus sample required.

A breakthrough in drug development

ExcepGen's proprietary technology enables high-yield production of proteins that have historically been difficult — or impossible — to produce in a laboratory setting.

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