    Single Molecule Measurement: Best Practices In Biomarker Detection

    By Mark Roskey, Vice President and General Manager, Applications and Reagents 

    The human genome encodes thousands of secreted proteins, each of which is an actor in the delicate biochemical balance of diagnostics. Even a slight change in any one of these proteins can mean the difference between sickness and health. Such a change also provides a critical window into the body and helps to direct diagnosis and treatment, however, the vast majority of secreted proteins are present in concentrations well below what conventional technologies can measure, and their role in human health is poorly understood. Researchers have continued to seek ways to detect and diagnose earlier and more accurately through protein detection, and have been unsuccessful at doing so – until now.
