In-line Optical Redox Probe
The PSI optical redox probe is based on real-time measurement of endogenous fluorophore concentrations that inform cellular-level redox metabolism. The innovative optical approach enables measurement of individual cells in agitated bioprocess cell cultures, based on cytometry-like data. The cellular level assessment of metabolism provides an information-rich data stream that rapidly informs engineers of the process status enabling timely guidance for adjustments for improved productivity.
