Comprehensive Cell Status Monitoring with CASY
Label-free with outstanding precision and reproducibility.
Thousands of users trust CASY
For years, CASY has been a reliable workhorse in cell-culture laboratories. CASY is referenced in more than 2,000 publications, you will find it in a myriad of publications and PhD theses and on laboratory benches around the world.
How does it work?
CASY quantifies cells and particles passing a measuring pore exposed to a low voltage electrical field. Based on a cell’s size and conductivity, a resistance signal is generated and recorded. Living cells generate high resistance signals due to their intact membrane structure. Dying or dead cells cause much lower resistance due to their increased membrane permeability and are measured by the size of their cell nuclei.

Enhance your work in the following applications
Mammalian Cell Counting
Before starting long-term experiments with high-value mammalian cells, it is important to precisely count cells. The CASY provides these comprehensive insights into cell health, viability and aggregation in one easy measurement.
Bacterial Cell Counting
CASY’s 45 μm capillary is ideally suited to monitor bacterial proliferation and aggregation. Researchers can plot changes in cell volume and number and monitor biovolume with an easy-to-use, dye-free tool.
T-cell monitoring
CASY can be used to monitor T-cell cultures for immunotherapeutic approaches by determining cell size and cell proliferation during T-cell stimulation.
