Fluorescence-based viability analysis

Nucleic-acid dye staining read by fluorescence detection to distinguish live from dead cells, extending accurate counting to viscous, pigmented or debris-heavy samples.

Where it's used

Cell counters and viability systems
Bench-top instruments that automate cell counting and viability assessment — image-based dye-exclusion counters, fluorescence-based analyzers and closed-cassette systems — replacing manual hemocytometer counting for daily cell-culture QC, bioreactor process monitoring and cell-therapy/cell-line release testing.
