Cell Microsystems Acquires Fluxion Biosciences to Broaden Cell Analysis Product and Services Portfolio. Read the Press Release

At Fluxion, we’re passionate about delivering cell-based solutions that facilitate the transformation of research discoveries into new ways to diagnose and treat patients. By characterizing molecular and cellular mechanisms of disease, Fluxion’s platforms help bridge the translational medicine gap, enabling rapid advances in disease research, drug discovery, and the development of diagnostic tests.

Engineered T-Cell


BioFlux is ideal for engineered T cell functional testing

Adoptive T cell immunotherapies such as CAR-T and TCR function by reaching their targets through a complex process that can involve interactions between multiple immune cell types and the target cells, as well as interactions between the immune cells themselves.

Modeling of this process, and ensuring that the engineered T cells have the desired functional properties, requires an in vitro model that can effectively mimic the physiological conditions in the human body. To achieve this, Fluxion has developed the BioFlux "artery on a chip" systems that serve as effective platforms for these functional cell assays. These assays are designed to assess the cell trafficking process, including homing, adhesion, avidity, and transmigration, and serve as the ideal platform for functional testing of engineered T cell therapies such as CAR-T and TCR.


BioFlux runs multiple parallel experiment using high resolution image capture. Experiments can be run as time lapse or endpoint, and can quantify adhesion, transmigration, and avidity. Charts above show relative adhesion and transmigration vs. time for various CAR-T candidates.



  • Study live cell transmigration in a physiologically-relevant assay using primary endothelial cells, cancer cells, or protein layers
  • Run the assay as time lapse to capture the process of adhesion and transmigration, or run as endpoint for high throughput discovery
  • Rapidly determine IC50 concentrations of multiple compounds under the same experimental conditions
  • Calculate number of adhered and transmigrated cells automatically utilizing BioFlux software analysis capabilities
  • Easily determine avidity by measuring bound fraction vs. shear stress
