Comparison of PrestoBlue and MTT assays of cellular viability in the assessment of anti-proliferative effects of plant extracts on human endothelial cells

PrestoBlue (PB) is a new, simple and extremely fast live assay to monitor cell viability and cytotoxicity. Herein, we compared two in vitro cytotoxicity assays, new (PB) and classic (MTT), in the assessment of viability of human umbilical vein endothelial cells (HUVECs) in the presence of selected plant extracts. The anti-proliferative effects of two extracts from medicinal plants, i.e., walnut husk extract and spent hop extract, used at the...
