Quanterix Corporation is a life sciences company. The Company is focused on ultra-sensitive biomarker detection, enabling breakthroughs in disease research, diagnostics, and drug development proprietary digital Simoa detection technology enables customers to reliably detect protein biomarkers at ultra-low concentrations in blood, serum and other fluids that, in many cases, are undetectable using conventional, analog immunoassay technologies. Its Simoa bead-based digital immunoassays utilize the basic principles of conventional bead-based sandwich ELISA. The HD-X is the Company's flagship instrument that empowers biomarker research and accelerates drug development. Its SR-X instrument is a compact benchtop instrument with a lower price point, more flexible assay preparation, and a wider range of applications. The Company's Spatial Biology solutions measure protein expression and cellular phenotypes within intact tissue while preserving spatial context and tissue architecture.
