Figure 1. Few effects of GC31 on the cell viability of human umbilical vein endothelial cells. Confluent human umbilical vein endothelial
cells (HUVECs) were incubated with GC31 (0.1, 1, and 10 μM), VP30 (10 μM), or LPS (1 μg/ml) for 24 h. The percentages of viable
cells were measured using the CellTiter 96 aqueous one solution cell proliferation assay (MTS) kit. Results of the absorbance
are the mean±SD (n=8).
