Seer, Inc. (California) engages in the development of proprietary engineered nanoparticles to provide access across the proteome. The company is headquartered in Redwood City, California and currently employs 134 full-time employees. The company went IPO on 2020-12-04. The company is developing products that open a new gateway to the proteome. Its Proteograph product suite is an integrated solution that includes proprietary engineered nanoparticles, consumables, automation instrumentation and software to perform proteomic analysis at scale in a matter of hours. The Proteograph has detected over 36,000 proteins across multiple species, and its performance and capabilities have been demonstrated in over 33 peer-reviewed publications, preprints and reviews. The Proteograph Product Suite is detector-agnostic and is adaptable to other protein detection instruments. The MS component of the Proteograph workflow is either provided by the researcher’s laboratory, can be outsourced to a third-party provider, or be run through the Seer Technology Access Center (STAC), which is its in-house service program. The company has launched Proteograph XT, which enhances the sample throughput of the Proteograph Product Suite and MS instrument.
