Celloger Pro application: Spheroid cytotoxicity

9 Sept 2025
Celloger Pro application: Spheroid cytotoxicity

In this video, CURIOSIS demonstrates how the Celloger® Pro can be used to observe the drug effect on spheroids in real-time. Spheroids were made from HEK293 cells that stably express GFP. Staurosporine and EthD-1 dead cell staining dye were applied, and the images were captured at 30-minute intervals over 24 hours using a Celloger® Pro with a 2X objective.

Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays. Find the best flow cytometers, cell counters and cell sorters in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.SpheroidsSpheroids are clusters of cells that have been grown in 3D culture to be used as <i>in vitro</i> model systems. These 3D microtissues can be used for toxicology testing, DMPK studies and many other applications involving cell analysis.
