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

HDX-MS for Biopharmaceutical Analysis

Ongoing

Intended Impact This project is designed to improve, test, and validate hydrogen/deuterium exchange mass spectrometry (HDX-MS) metrology for the determination of dynamical properties of therapeutic proteins and glycoproteins. Objectives Explore structure-function relationships between glycan

Monoclonal Antibody Mass Spectral Libraries

Ongoing

Intended Impact Modern mass spectrometers used in the field of proteomics and glycomics are capable of profiling hundreds, and even thousands of molecules in a single experiment. Each of these compounds is isolated and fragmented to form a mass spectrum. Therefore, interpretation of these mass

Comparative Mammalian Proteome Aggregator Resource (CoMPARe) Program

Ongoing

Comparative proteomics strives to gain insight into key underlying molecular changes that result in unique phenotypes across related taxa. Proteomic analysis complements comparative genomics by providing evidence of protein abundance, orthogonal to gene copy number and amount of transcript. To
