The company leverages over 20 years of scientific experience and proprietary reagents to deliver active, pure, and structurally native proteins for clients in pharma, biotech, and academia. Its core value proposition is enabling faster and more reliable drug discovery by providing high-quality protein targets that are critical for structure-based drug design, assay development, and therapeutic antibody generation. As part of the Eurofins network, it benefits from integrated downstream services and a global client base.

Proprietary platform for the extraction, stabilization, and purification of fully native, wild-type membrane proteins and difficult-to-express soluble proteins, using custom reagents and protocols.
