Fig. (6) Fluorescent/Fluorescent and Fluorescent Luminescent Viability and Cytotoxicity Assays. MultiTox-Fluor or MultiTox-Glo Reagents (Promega Corporation) were added to a 1536 well plate after Jurkat cells had been treated with 30µg/ml digitonin or vehicle. Each well is represented as a ratio of the viable and non-viable values measured using the chemistries.
