3D Orientation Imaging

Ongoing
We have developed 3D orientation imaging methods for both infrared (IR) and coherent anti-Stokes Raman scattering (CARS) signals. The two approaches are complementary to each other. The IR-based 3D orientation imaging is broadly applicable to any pair of non-parallel IR transition dipole moments

Orthogonal Measurements

Ongoing
Definitions: Orthogonal measurements: Measurements that use different physical principles to measure the same property of the same sample with the goal of minimizing method-specific biases and interferences. Complementary measurements: Measurements that corroborate each other to support the same

Quantitative Flow Cytometry Measurements

Ongoing
Flow cytometry is an essential tool for: basic biotechnological and immunological research, the clinical discovery of potential therapeutics, development and approval of drugs and devices, disease diagnosis, and therapeutic treatment and monitoring For example, flow cytometry is commonly used in pre

RMAT Laboratory Programs

Ongoing
Examples of Current Activities: Cell Counting and viability are key measurements critical for decision making from R&D to manufacturing. We recently developed an approach for evaluating the quality of cell counting measurements through experimental design and statistical analysis that does not

Serology and Neutralization Assays for COVID-19

Ongoing
Multiplexed bead-based SARS-CoV-2 serological assay We have developed a validated multiplexed bead-based SARS-CoV-2 serological assay that measures different antibodies produced by a patient (IgG, IgM, IgA). In collaboration with the NIST Applied and Computational Mathematics Division, we have

Single-Cell Manipulation and Measurement

Ongoing
Mammalian cells are an important source material for applications in regenerative medicine, gene therapy, engineering biology, and genome editing. Traditional tools for manipulating mammalian cells operate at a bulk cell population level without precision manipulation of individual cells

Synthetic Fecal Metabolite Calibrant Solution (RGTM 10212)

Ongoing
Metabolomics is an exciting and dynamic field in life sciences that harnesses cutting-edge technologies to identify and characterize small molecules, or metabolites, within cells, tissues, or organisms, collectively known as the metabolome. The wealth of evidence in the literature underscores the

U.S. TAG for ISO/TC276: Biotechnology

Ongoing
Get involved: Interested U.S. Stakeholders may participate in the US TAG at no cost. Membership provides access to all ISO/TC 276 and US TAG documents, including standards under development. Please click here to join. Contribute to standards development: Please click here to review, submit comment

Thermodynamic Principles Describe and Predict Cell Populations

Ongoing
Heterogeneity of cell populations indicates the many ways cells can process information. We study heterogeneity in gene expression by inserting a gene for a fluorescent protein downstream of the gene we are interested in, and we examine large numbers of cells by imaging or flow cytometry. We think

Tissue Engineering

Ongoing
Tissue Engineering Measurands: Tissue engineering measurands are confusing to discuss and a charting method to improve communication is demonstrated. Measurement Assurance Strategies for Regenerative Medicine: Reliable methods for assessing product consistency and quality. Regenerative Medicine

Tissue Engineering Measurands

Ongoing
Making a Measurand Chart: A measurand chart can be created for any measurement by writing down all the measurands that occur during the measurement. The panels should not be procedural steps, such as “wash the sample with buffer” or “centrifuge the microfuge tubes”. Consider if the measurement has a
