NanoImaging Services (NIS), a California-based company that provides cryo-electron microscopy (cryo-EM) services for drug discovery and development, announced on Monday that it has acquired Proteos Inc, a Michigan-based contract research organisation (CRO) specialising in protein production services for discovery research.

This acquisition combines Proteos' expertise in protein production with NIS's cryo-EM solutions, creating an integrated offering for customers seeking structure-based drug discovery and protein production services.

John Rigg, NIS CEO, said: "This union further establishes NIS as a market leader in structure-based drug discovery and enables us to combine upstream protein expression with cutting edge downstream analysis and cryo-EM imaging to best meet the evolving needs of current and future customers."
