Like all analytical instruments, cell viability analyzers require initial qualification and routine QC to demonstrate both that they are suited to their intended use, and demonstrate ongoing capability. ViaCheck™ Concentration and Viability Controls are microsphere-based calibrators that support quality programs for imaging-based cell viability analyzers across a range of cell (bead) concentrations and %viabilities. Recent exponential growth in biomanufacturing has placed an even greater emphasis on the controls utilized in the validation and QC of cell viability analyzers.
