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

Fluorescence Microscopy Benchmarking: Overview

Completed
A challenge in using microscopy is how to compare and validate data from different instruments, and how to determine that the microscope performance today is the same as yesterday. NIST is developing a practical, automated approach to implementing performance benchmarking methods that will

Fundamental Interaction Mechanisms of Engineered Nanomaterials with DNA

Completed
Intended impact Nanotechnology research has resulted in the rapid creation of engineered nanomaterials with many foreseeable applications in medical imaging/diagnosis and in drug delivery. However, there is a notable scarcity of both acute and chronic human toxicity data for these new materials

Improved Benchtop Connectivity to Complex Microfluidic Devices

Completed
Intended impact Microfluidic devices with many fluidic and pneumatic inlets are difficult to connect to benchtop reservoirs and controllers. Many hours can be spent sorting, untangling, and connecting tubing to a single device. If one then finds that the device is not fully functional, the process

Label-free imaging of cells and their extracellular matrix by SPR imaging

Ongoing
Cellular remodeling of their neighboring environment, extracellular matrix (ECM), is an important biological process from development biology, to wound healing, to diseases and cancers – this is a challenging process to measure and quantify. Surface plasmon resonance imaging (SPRI) has been

Live Cell Imaging of Induced Pluripotent Stem Cell Populations

Ongoing
As part of our program in Cell Biology , our live cell image program supports the advancement of induced pluripotent stem cell (iPSC) technology in three ways: 1) Identification of process control measurements: A critical component to the translation of iPSCs into therapeutic applications is to

Measurement Assurance for Quantitative Cell Imaging by Optical Microscopy

Ongoing
Light microscopy is unparalleled as a quantitative technique for studying cell biology, but assuring that the results of measurements and analyses are accurate, repeatable and sharable is challenging. Here we provide information on reference materials, protocols and approaches for evaluating the

Measurements for minimal cells

Ongoing
Minimal cells are cells whose genome has been stripped of all but those genes essential for replication, in a process called "genome minimization." NIST and collaborators demonstrated genome minimization coupled to single cell imaging as a powerful approach to investigate the minimal genetic

Measuring Cell Viability in Scaffolds

Ongoing
Project Goals Primary Goal: Advance measurements of cell viability in manufactured tissues Establish working group of industry stakeholders to guide work Develop model scaffold-cell-assay system for measuring cell viability in scaffolds Validate measurement system by orthogonal test methods Assess

Metrology For Cell-Free Expression Systems

Ongoing
Cell-free expression systems are poised to advance the US bioeconomy and play a key role in ensuring US manufacturing resilience. NIST has several, on-going projects in its growing portfolio to promote reproducibility, new measurement methods, and best practices and standards in cell-free expression

Mouse Allelic Ladder

Ongoing
What is an allelic ladder? An allelic ladder is a mixture of highly characterized alleles (known size and sequence) that are generated using the same primers as the test samples and are used during capillary electrophoresis for accurate allele call determination. Why is an allelic ladder important

Next Generation Metrics for Cell-Based Therapies and Regenerative Medicines

Ongoing
The science of human health and disease often includes studies of cells, the smallest unit of biological complexity. Microscopic imaging is an important tool in these studies and can provide morphological and molecular information. Molecular microscopic data is most often collected in a static mode

NIST/EDRN Cancer Biomarker Collaboration

Completed
Our lab is one of the EDRN Biomarker Reference Laboratories working with the EDRN discovery labs to improve the quality of the measurements done on new cancer biomarkers for early detection of cancer and for cancer risk. TECHNICAL APPROACH Evaluate current assays used for detection of cancer

NIST Flow Cytometry Standards Consortium 

Ongoing
Advances in cell and gene-based therapeutics as well as other regenerative medicine products have increased the need for high quality, robust, and validated measurements for cell characterization. Flow cytometry, including imaging cytometry, has emerged as an important platform due to its ability to

NISTCHO

Ongoing
NISTCHO, a new mammalian cell line of interest to the biopharmaceutical and biomanufacturing communities, is now available from the National Institute of Standards and Technology. This Chinese hamster ovary (CHO) cell line has been engineered by MilliporeSigma to express a non-originator version of

Prototype Cell Assay Measurement Platform (P-CAMP)

Ongoing
A systematic approach to the development of robust biological assay includes identifying and ranking the sources of variability in an assay protocol. With a focus on mammalian cellular assays, the Prototype Cell Assay Measurement Platform ( P-CAMP) laboratory was designed and built to take advantage

Quantification of Cells with Specific Phenotypic Characteristics

Ongoing
Internationally recognized and validated reference standards are currently not available in the field of cellular phenotyping by flow cytometry. The World Health Organization (WHO) has issued an open letter to the manufacturers of CD4 + T-cell enumeration technologies for the HIV/AIDS epidemic
