Nanopore platform for single-molecule full-length protein sequencing

Portal Biotech is a biotechnology company developing benchtop nanopore instruments for single-molecule proteomics and metabolomics.

Its platform uses bioengineered nanopores coupled with machine learning to sequence intact, full-length proteins at the single-molecule level, capturing protein mutations, modifications and heterogeneity in real time.

Evolved from over a decade of academic nanopore research in the Maglia Lab at the University of Groningen, the technology targets drug discovery, diagnostics and biosecurity applications.
