Trusted AI framework for a new class of Standard Reference Materials and Data with exquisitely characterized uncertainty for billions of properties

Ongoing

The measurement of diverse molecular classes in biospecimens containing millions of molecules, known as omics, is increasingly important in the life sciences and medicine, and used to find novel cancer therapeutics, discover COVID-19 infection pathways, and diagnose diseases. NIST RMs and SRDs for

Performance Metrics for Proteomics

Ongoing

Intended Impact Proteomics experiments designed to identify protein markers specific to a particular disease or disease state rely on repeatable identification of proteins within a control set. Repeatability provides statistical assurance that clear differences between two sets (e.g. sick vs
