The SIMOA digital detection system can detect single molecule in bloodstream. The Simoa HD-X enables best-in-class assay performance for quantification of protein biomarkers in small volumes of serum, plasma or cerebrospinal fluid. A broad menu of single- and multi-plex assays are available across several areas of medical research, including neurology, oncology, cardiology, inflammation and infectious disease.​

​

1. To trap single protein molecules with first-class class antibodies coupled to paramagnetic beads in femtolitre-sized wells.

2. the sensitivity of Simoa HD-X assays can be 1000 times greater than conventional immunoassays.

3. Previously undetectable quantities of proteins are able to be accurately measured.

4. Reproducibility of the Simoa HD-X is unmatched, with intra- and inter-assay coefficient of variation typically less than 5%.
