Primary Bioscience

Primary Bioscience is an early-stage biotech firm pioneering next-generation proteomics through single-molecule protein sequencing. Its core technology is designed to provide a comprehensive, unbiased view of the proteome, which could revolutionize disease detection and biomarker discovery by identifying protein variations that current mass spectrometry-based methods often miss. Operating in the Diagnostics and Digital Health sectors, the company is pre-revenue and in the platform development stage. Its success hinges on translating its ambitious technological vision into a functional, commercial-grade instrument.

Single-molecule protein sequencing device designed for unbiased, comprehensive sequencing of all proteins in a sample, capable of detecting single residue substitutions, splice variants, and post-translational truncations.

Competes in the next-generation proteomics space against companies like Quantum-Si (public) and Nautilus Biotechnology (public), which are also developing high-throughput, single-molecule or single-cell proteomic analysis platforms. The competitive field is focused on overcoming the limitations of traditional mass spectrometry.
