Senior Research Associate, Assay Development

Personalized, cell-based therapy is emerging as a paradigm-shifting strategy in healthcare. To harness the potential of cutting-edge cellular engineering, stringent process controls must be put into place that monitor and measure critical parameters of the cell product at every step, from patient sample acquisition to drug product release. In essence, the process is the product.

Accellix offers a streamlined flow cytometry workflow solution that couples dried ambient-stable reagents, automated cell sample preparation and data acquisition within a single-use microfluidic cartridge, and customized auto analysis. The combination results in robust multiparametric analysis with ‘mix and read’ simplicity, enabling standardized process controls for our cell and gene therapy customers.
