First of all, watch the video below.
A Santa Cruz company is now previewing a nanopore device that could be a major disruptor in molecular testing. The device is the size of a glucometer and could take all kinds of testing—perhaps someday even cancer-tracking liquid biopsies—into the home with its ease of use and ability to work with thousands of different assays.
Two Pore Guys, named for the pores not the guys, is a spinout from UC Santa Cruz and one of a growing biotech community on the west side of Santa Cruz, CA. The company has yet to do beta testing and is focused now on scaling up manufacturing of the small, relatively simple devices. CEO, Dan Heller, says Two Pore Guys has no plans to develop their own tests but will stay focused on the platform.
“We could make ten or fifteen assays and go to market with them, but why not let others make thousands and thousands of assays?” Dan asks. "They’ve already spent billions of dollars and decades developing primers or capture molecules for antibodies. Why not just give it a new life and let them sell it into the market? It's a revenue share."
So what tools might this replace? Dan lists the standard lab machines for PCR, HPLC, and mass spec. “There’s many uses of existing lab equipment that could be done on our device more quickly, cheaply, easily,” says Dan.
Based on recently developed nanopore technology, the small device looks remarkably straight forward. A molecule—just about any molecule-- is pulled through a nanopore by an electric current. The impedance of the current is the measure of the molecule. Though the device does not currently sequence DNA, its possibilities to replace other large life science tools does seem all the more real in a time when Oxford Nanopore’s small sequencing devices--also partly developed at UCSC—are proving themselves powerful tools.
Listening to Dan, the broad range of molecules and applications becomes dizzying: diagnostic testing such as liquid biopsy tests for cancer (the company is currently doing a study with UC San Francisco for a KRAS liquid biopsy test), infectious disease, border security, agriculture, animal health, and environmental testing.
It leaves us with this question in the end: why was this not done before?
