Analysis of drug-induced effects on cellular viability. Flow cytometric analysis (FC) of the fraction (%) of viable, apoptotic, and necrotic human neuronal SH-SY5Y cells by propidium iodide (PI) versus Annexin V, after treatments with different concentrations of guarana (3.125, 12.5, and 50 mg/mL), caffeine (0.125, 0.5, and 2 mg/mL), taurine (1, 4, and 16 mg/mL), and their combinations for 4 hours.
