Consistency Analysis and Uncertainty in ‘omic Data

Ongoing
‘Omics is increasingly moving out of the laboratory and towards use in industrial and commercial applications. For instance, in biomanufacturing, there is a need for quality control when developing biotherapeutics, which will almost certainly require a machine-learning classifier to separate

Data Infrastructure for Biomanufacturing Process Control

Ongoing
Objective The objective of this project is to develop measurement science that includes ontology models, ontology expression (axiomatic) patterns, guidelines for qualifying those ontologies, and distributed ontology development software that will allow U.S. manufacturers to have better access to

Development of Biomarker-based Systems for Cancer Detection and Therapy

Completed
Intended impact Although significant progress has been made in both the understanding and treatment of cancer during the last thirty years, it remains the second leading cause of death in the US. The cancer community has set a goal to eliminate cancer-related suffering and death by 2015. To achieve

Development of Enhanced mRNA Amplification Using Microfluidics

Completed
Intended Impact Tissue samples frequently contain multiple cell types. New methods (e.g. laser capture microdissection) enable the segregation of small quantities of individual cells and cell types, but the current methods to analyze global gene expression do not provide highly efficient profiling

Development of SRM 2669 for Accurate Assessment of Arsenic Exposure

Ongoing
Arsenic exposure in the U.S. population is an important part of the NHANES program conducted by CDC because dietary exposure to arsenic can cause serious health effects. A major challenge in the arsenic exposure assessment is that arsenic exists as various species in nature, and the toxicity of

Dietary Supplement Laboratory Quality Assurance Program (DSQAP) Consortium

Ongoing
The objective of the DSQAP Consortium is to develop and evaluate measurement methods and standards to support quality and safety for the dietary supplement testing community. Approximately 75% of the U.S. population takes dietary supplements, including vitamins and mineral supplements, representing

Dietary Supplement Laboratory Quality Assurance Program (DSQAP)

Ongoing
Approximately 75% of the U.S. population takes dietary supplements, including vitamins and mineral supplements, representing an annual expenditure of more than $20 billion. Regulations, driven by reported cases of inaccurate labeling, adulteration, contamination (with pesticides, heavy metals, or

Digital PCR

Ongoing
With appropriately validated assays, digital polymerase chain reaction (dPCR) determines the number of DNA targets (copies) per reaction partition, without the need for a standard curve. Reaction partitions can be in the form of fixed chambers in a microfluidic device, referred to as chamber digital

ERCC 2.0: Developing a New Suite of RNA Controls

Completed
Requested RNA Control products include: Transcript isoforms; New and improved messenger RNA mimics and mixture formulations; microRNA and other small RNA molecules; and Cancer fusion transcripts. ERCC technical working groups are developing design specifications, RNA control products, and analysis

Evaluating Measurement Quality of Microfluidic Cell-based Assays

Completed
Impact and Customers Our work establishes metrics for measurement quality and reproducibility for cell-based assays within microfluidic devices. Many novel microfluidic devices are being created that permit new measurements or enable new biological functions to be tested; however, characterizations

External RNA Controls Consortium

Completed
While early gene expression measurements with DNA microarrays were groundbreaking in their ability to reveal biological activity, the results were irreconcilable and irreproducible. Industry leaders approached the National Institute of Standards and Technology (NIST) in 2003 for help with addressing

Fatty Acids in Human Serum and Plasma Quality Assurance Program (FAQAP)

Completed
Interlaboratory comparison studies of the FAQAP focused on the measurement of 24 fatty acids in selected serum and plasma matrices. Frozen or freeze-dried serum or plasma samples were sent to laboratories for analysis together with control materials. Results were returned to NIST for data evaluation

Flow Cytometry Lab

Ongoing
Current Capabilities ERF value assignment measurement service for traceable ERF value assignment to microparticles, Aseptic sorting of cell lines, and primary cells Quantitative measurements of cell surface and intracellular biomarkers by estimating antibody bound per cell Accurate enumeration of

Food Nutrition and Safety Measurements Quality Assurance Program (FNSQAP)

Ongoing
As part of a revamp of QAPs in 2021, NIST established the FNSQAP to support the NIST Food Safety Program and Measurements and Standards to Support Nutrition Labeling. Participants measure nutrient components (e.g., minerals, vitamins, fatty acids, dietary fiber) and contaminants (e.g., toxic

Gene Delivery Systems

Ongoing
Viral Vectors Viral vectors are a critical tool for delivering DNA or RNA into patient’s cells. Common viral vectors for gene therapy include adenovirus, lentivirus, and adeno associated virus. Administration of viral vectors can occur in vivo or ex vivo , such as for adeno associated virus or

Genome in a Bottle

Ongoing
Consortium goals: The Genome in a Bottle Consortium is a public-private-academic consortium hosted by NIST to develop the technical infrastructure (reference standards, reference methods, and reference data) to enable translation of whole human genome sequencing to clinical practice and innovations
