ATEM Structural Discovery

ATEM Structural Discovery is a private German cryo-electron microscopy services and technology company serving pharmaceutical and biotechnology clients. The company operates a software-enabled, AI-integrated cryo-EM platform used for 3D structure determination, high-throughput epitope mapping, lipid nanoparticle characterization, adeno-associated viral vector characterization, and GMP TEM viral particle characterization. Rather than developing its own therapeutic pipeline, ATEM functions as a contract research and analytical partner that helps customers accelerate structure-based drug discovery, lead selection, and quality control for advanced therapeutics. Its offerings are positioned around difficult biological targets, including membrane proteins and large assemblies, as well as emerging modalities such as LNPs, AAVs, biologics, and small molecules. ATEM has also highlighted a strategic partnership with Charles River to expand client access to cryo-EM capabilities and GMP-oriented workflows.
