Peripheral blood mononuclear cells (PBMCs) are often processed to separate from whole blood by density gradient centrifugation. Those cells are consist of lymphocytes (T cells, B cells, NK cells) and monocytes, commonly used in the field of immunology, cell therapy, infectious disease and vaccine development. Monitoring and analyzing viability and concentration of PBMC is crucial for the clinical laboratories, basic medical science research and immune cell production.

In the past few decades, cell therapy has made great progress, and cell therapy itself is no longer a simple collection of cells and infused back. Cells are now often required to be bioengineered, such as CAR-T cell therapy. We aim to provide you with standardized, GMP level equipment for cell quality control.

The Countstar instruments is image base cell analyzer, we offer a smarter approach for cell analysis from research to industry. The Countstar provide platforms for precise determination of viability and concentration of mammalian cells, yeast, algae, PBMC, T cell and other primary cells.

The Countstar S2 System combines the two fluorescence channels plus a bright field digital microscope, an image cytometer, and a cell counter in a single bench-top instrument. This application-driven, compact, automated cell imaging system provides an all-in-one solution for cell counting, cell viability and Cell transfection efficiency through the use of preconfigured biological applications (BioApps). They are specifically optimized for analysis of primary cells from peripheral blood, including PBMC, CAR-T, NK cell and MSC, which commonly used in cell therapy.
