Cell Line Authentication

Ongoing
Cell Line Authentication – The scientific community has responded to the misidentification of human cell lines with validated methods to authenticate these cells; however, there are few assays available for nonhuman cell line identification. We have developed multiplex polymerase chain reaction (PCR

Cell Viability for Advanced Therapies

Ongoing
In the Biosystems and Biomaterials Division at NIST, we have established several technical programs to support the development and implementation of cell viability assays in advanced therapies. These programs address key needs in cell viability assay development including selection and development

Cell-based Assay for Mechanistically-based Prediction of Cytoxicity

Completed
Ricin is a type 2 ribosome inactivating protein (RIP) belonging to the A-B family of toxins and is of particular interest because of its potential use as a biological weapon and the dearth of rapid and sensitive assays that could assist detection and decontamination. The ricin toxin inhibits protein

Certification of a Standard Reference Material for Cytomegalovirus (CMV)

Ongoing
The goal of this project is to provide a SI-traceable reference material for use by calibrant and reagent manufacturers in production of their own calibrants and standards. Clinical laboratories with in-house methods would be able to use the reference material for production of their own quality

Chinese hamster ovary (CHO) cell line authentication

Ongoing
Intended impact To develop a PCR based multiplex assay that can be used to authenticate Chinese hamster ovary cell lines which are important in the production of biological therapeutics. Objectives Identify tetranucleotide STR markers by searching the CHO genome using BLAST Design and optimize a

Combating Antibiotic Resistance

Ongoing
We are developing in vitro systems to generate controlled chemical and community environments that mimic the features of real-world that are important determinants for evolutionary rate and resistance potential. In addition, we are developing tools to isolate and analyze single bacteria along the

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

Comparative Serum Proteomics Project

Ongoing
State-of-the-art biomolecular analysis is no longer limited to model organisms and is becoming routine in non-model organisms. Major drivers of this emerging bioanalytical capacity include increasing accessibility and quality of sequenced genomes as well as high-resolution fast-duty cycle mass

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

Controlling Microfluidic Cell Cultures

Completed
Intended impact: Cell behavior is powerfully modulated by local extracellular cues. However, the number of parameters that affect cell behavior is large, and include soluble signaling molecules, dissolved gases, the chemistry and mechanics of the extracellular matrix, and the proximity and behavior

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

Decontamination of Biological Threats in Water Supplies

The outcome of the project was to provide the EPA with a technical resource document that could be used to guide emergency responders and for longer-term microbial decontamination of building water systems. This project was done in collaboration with the Building and Fire Research Laboratory (BFRL)

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 the NIST Prototype Advanced Biometrology Laboratory

Ongoing
Currently, NIST is investing in a new type of metrology laboratory that is focused on the unique reference material and high quality assay protocols that are needed in the regenerative medicine and biotechnology communities. The laboratory design is centered on automation that can set up 1000’s of

Development of Proteomics-Based Methods for Protein Quantification

Ongoing
Reference measurement procedures and standard reference materials help ensure that routine clinical assays provide accurate results across different laboratories and over time. Lists of such higher-order methods are published by the Joint Committee for Traceability in Laboratory Medicine (JCTLM)

Development of Rapid Multiplex PCR Techniques

Ongoing
With the continuing development of miniaturization technologies such as microfluidic and micro-capillary devices there is a desire to reduce the overall time required to type DNA samples. Such miniature devices could be used for initial screening at a crime scene, at a border, or at airports. There
