About
Pumpkinseed is The Biology Mining Company. We built deSIPHR — a proprietary nanophotonic chip platform — to read proteins directly, at single-molecule resolution, without prior knowledge of what's in a sample. Proteins execute nearly every function in biology, yet the tools to measure them have always been indirect, database-dependent, and incomplete. deSIPHR changes that. We are based in Palo Alto, CA and founded out of Stanford University.
