Size and Number Concentration Measurements of Polystyrene Nanoparticle Suspensions using Several Different Techniques

September 8, 2022
Paul C. DeRose, Kurt D. Benkstein, Elzafir B. Elsheikh, Adolfas K. Gaigalas, Sean Lehman, Dean C. Ripple, Linhua Tian, Wyatt N. Vreeland, Adam York, Yu-Zhong Zhang, Lili Wang
The number concentrations of nominal 100 nm, 200 nm and 500 nm diameter, fluorescently-labeled polystyrene nanosphere suspensions were measured using seven different techniques. Diameter values were also measured where possible. The diameter values were

Expanding NIST’s Calibration of Fluorescent Microspheres for Flow Cytometry to More Fluorescence Channels and Smaller Particles

September 16, 2020
Paul C. DeRose, Linhua Tian, Elzafir B. Elsheikh, Aaron A. Urbas, Yu-Zhong Zhang, Lili Wang
NIST, NIH and other industry stakeholders have been working together to enable fluorescence intensities of flow cytometer calibration beads to be assigned quantitative “ERF” values with high accuracy and precision. The ultimate goal of this effort is to

An accurate and rapid single step protocol for enumeration of cytokine positive T lymphocytes

Deepa Rajagopal, Linhua Tian, Shiqiu Xiong, Lili Wang, Jonathan Campbell, Luisa Saraiva, S Vessillier
Activation of T lymphocytes leads to differentiation, characterized by the ability to induce production of cytokines. Accurate determination of cellular subsets that secrete particular cytokine(s) is therefore, a significant parameter for functional
