The right protein for every downstream experiment, from construct design to full characterization.

Proteros brings together 70+ scientific experts with decades of experience in delivering high-quality proteins for the most challenging drug discovery targets. With more than 10,000 projects completed, 3,500+ purification runs per year on 85+ on-site ÄKTA systems, a >90% success rate for difficult targets, and 350+ targets with established production routes available in Gallery Mode, Proteros provides reliable access to fit-for-function proteins tailored to the needs of modern discovery programs.

From construct design, expression, and purification to advanced analytical characterization, all capabilities are integrated under one roof. The company’s expertise spans a broad range of challenging target classes, including membrane proteins (GPCRs, ion channels, and transporters), kinases, DNA/RNA-binding proteins, helicases, PROTAC and molecular glue targets, and RIPTAC-related proteins. Proteros also produces assembly-right biologics, including antibody fragments (Fab, Nb), as well as complex multi-protein assemblies, supported by comprehensive physicochemical and functional characterization.
