Probe Life is a biotech company located in Palo Alto, CA. We are creating novel analytical technologies that help biopharma scientists do their work better and faster. Our latest instrument, the Gator, allows label-free analysis using reflectometric interference spectroscopy (RIfS) to measure protein-protein interaction. By fusing the engineering and the sciences, we are able to achieve more convenience, better performance, and lower cost than the existing products.
