Cytek Biosciences Adds Ability to Detect Subcellular Particles to Its Industry-Leading Cell Analysis Systems

New Enhanced Small Particle (ESP) Detection Option for Cytek Northern Lights and Cytek Aurora Systems Expands Capabilities of Small Particle Research

FREMONT, Calif., May 20, 2024 (GLOBE NEWSWIRE) -- Today Cytek Biosciences, Inc. (Nasdaq: CTKB), a leading cell analysis solutions company, officially announced its Enhanced Small Particle (ESP) Detection Option for its flagship Cytek Aurora and Cytek Northern Lights cell analysis systems. With this optional upgrade, these systems show superior sensitivity and resolution of subcellular materials, including extracellular vesicles (EVs), while maintaining high resolution and high parameter capabilities for cell analysis, making them the preferred choice among researchers and clinicians.

Exosomes are the most commonly studied EV, with a market estimated to increase from $227.5 million in 2023 to $1.3 billion by 2028, at a compound annual growth rate (CAGR) of 42.2% from 2023 through 2028¹. Researchers studying exosomes, as well as viruses, small bacteria, and nanoparticles, are moving to flow cytometry because of its high throughput and quantitative detection capabilities. Typically, flow cytometers have been unable to detect particles smaller than 500 nm, limiting their use to the study of cells and larger particles. Now, particles as small as 70 nm can be studied label-free on Cytek’s Full Spectrum Profiling (FSP) analyzers, giving researchers the ability to characterize the full emission spectra of small particles. Cytek is now positioned to be a leader in the growing small particle research market.

With Cytek’s new ESP Detection Option, the rapidly growing areas of research conducted on viruses, small bacteria, EVs, nanoparticles, and other subcellular particles for therapy development and biomedical research are being advanced. EVs can be used in various applications such as biomarker development, diagnostic tools and therapeutic development for delivery of drugs.

“Quantitative measurements of individual EVs are critical to progress in the field, and the excellent fluorescence performance of the Cytek Aurora and Northern Lights systems enables us to make sensitive measurements of both EV size and cargo,” noted the Scintillon Research Institute’s John Nolan, Ph.D. “The new ESP Detection Option provides greatly increased light scatter sensitivity, enabling the discrimination of EV sub-populations with distinctive composition and ultra structure that can affect light scattering. These capabilities empower us to better understand the biogenesis of different types of EVs as well as their biological functions toward using these to both detect and treat disease.”
