The CTEGD Cytometry Shared Resource Lab is growing!

CTEGD’s Cytometry Shared Resource Laboratory recently added a Malvern Panalytical NanoSight NS300 to their suite of cytometry instruments. This was a donation from the laboratory of Dr. Stephen Hajduk.

The NanoSight allows rapid analysis of the size distribution and concentration of all types of nanoparticles from 0.01 – 1 µm in diameter.  It is important to monitor and control the isolation and purification of extracellular vesicles (EVs) while conducting research into their function. NanoSight NTA (Nanoparticle Tracking Analysis (NTA) utilizes the properties of both light scattering and Brownian motion to provide quick and easy characterization of both the size and concentration of vesicles in aqueous buffers, giving confidence in the quality of the sample used in any downstream experiments.

Researchers across the UGA campus are investigating the role of EVs in T. brucei and N. fowleri infections, neural stem cell extracellular vesicle uptake and neutrophil uptake of exosomes isolated from cystic fibrosis sputum.

The NanoSight is the second instrument CSRL added in 2022 (see the Cytek Aurora Spectral Cytometer announcement) and increases the number of cytometry instruments available for CTEGD and the UGA research community use to 11.

The CSRL continues to provide access to state-of-the-art cytometry analyzers and sorters to researchers at the University of Georgia and across the scientific community. In addition to the instruments, the facility also provides expert advice and consultation for the design and analysis of flow experiments.

With the generous financial support of The Office of Research, Cytometry Shared Resource Lab, Center for Tropical and Emerging Global Diseases, Department of Infectious Diseases, and UGA faculty members Rick Tarleton, Mark Tompkins, Chet Joyner, and Sam Kurup, the CTEGD Cytometry Shared Resource Laboratory (CSRL) recently added the Cytek Aurora Spectral Cytometer to its facility. This new instrument provides a high level of flexibility to the researcher and complements the other instruments available at the facility.

“It’s great to be able to bring this exciting new resource to campus in support of the incredible research UGA members are conducting,” said Julie Nelson, CSRL manager.

Flow cytometry is a technique for measuring characteristics of cells or particles using laser excitation and innate fluorescence emission or emission from dyes added to identify cells or particles and their function in experimental biology.  In the past 30 years, this technology has revolutionized many areas of cell biology research including the study of viruses, bacteria, infectious diseases, and cancer.  This technology has also proven useful in genetic studies of plants.

The Aurora Spectral Cytometer delivers high-resolution data at the single-cell level to resolve the most challenging cell populations, such as cells with high autofluorescence or low levels of expression of key biomarkers, regardless of assay complexity. With 64 emission detectors and 5 lasers for excitation, the Aurora can resolve almost any fluorescent marker currently on the market. It can also evaluate dyes under development that can be excited by one or more of the 5 lasers available.

“This cytometer expands our capabilities from a limit of 24 parameters to 64 making it ideal for high dimensional immunophenotyping,” said Nelson. “But because of its unique spectral emission detection, it is also the best instrument for looking at highly autofluorescent cells, such as macrophages and liver cells, regardless of how many markers are needed for the assay.”

For more than 20 years, the CSRL has provided access to state-of-the-art flow cytometry analyzers to researchers at the University of Georgia and across the scientific community. In addition to the instruments, the facility also provides expert advice and consultation for the design and analysis of flow experiments.

The CSRL is hosting a free webinar on the CYTEK Aurora on Friday, January 28 at 1:00 pm with Christopher Fleming, Ph.D. To register:
