| Cytotoxicity of venoms from eleven medically important snakes found in Southeast Asia (Naja kaouthia, Naja siamensis, Naja sumatrana, Ophiophagus hannah, Bungarus candidus, Bungarus fasciatus, Enhydrina schistosa, Calloselasma rhodostoma, Trimeresurus purpureomaculatus and Tropidolaemus sumatranus) was determined, based on the MTS cytotoxicity assay, which determines the survival of viable cells in monolayer MDCK and Vero cell cultures upon exposure to the snake venoms. Snake venom toxicity was expressed as the venom dose that killed 50% of the cells (CTC50) under the assay conditions. Venoms of C. rhodostoma (2.6 µg/mL, 1.4 µg/mL) and O. hannah were the most cytotoxic (3.8 µg/mL, 1.7 µg/mL) whereas N. siamensis venom showed the least cytotoxicity (51.9... |
