Parhelia Biosciences

Our company Parhelia Bio provides a simple, efficient, and affordable solution to tissue auto-staining and automation for research, diagnostic, and pathology labs. We (the founders of Parhelia Bio) met at Stanford while doing our postdocs in the Nolan lab. Together we collaborated on the development of CODEX ultra–multiplexed staining technology and co-founded Akoya Biosciences (NASDAQ:AKYA) to commercialize CODEX and related methods. CODEX and Opal (later acquired by Akoya from Perkin Elmer) are now considered key technologies in the rapidly growing field of spatial biology. From our lab work at Stanford, it became clear that multistep staining protocols such as CODEX itself require a significant effort. Achieving great CODEX staining takes hours of focused hands-on time and we saw that for many of our collaborators, it took months to master the protocol when they first started.
