From: Violacein induces cell death by triggering mitochondrial membrane hyperpolarization in vitro
Effects of violacein on the cell viability of CHO-K1, MRC-5 and HeLa cells, as determined by the Trypan blue dye exclusion method after exposure to 0.75–6 μM violacein for 24 (a) and (b) 48 h. The viability of untreated cells was expressed as 100 %
