Upon insertion of a counting slide, the TC20 cell counter rapidly provides a total cell count (with or without trypan blue staining) and assesses cell viability via trypan blue exclusion.

(see ‘Two staining mechanisms for cell counting in ... For example, a significant limitation of trypan blue is its inability to differentiate between red blood cells and PBMCs.

The traditional trypan blue can be used with the LUNA-II™, as well as the safer Erythrosin B. Both dyes produce consistently accurate cell count and viability data with the LUNA-II™.
