From: The paraspecific neutralisation of snake venom induced coagulopathy by antivenoms

The neutralisation of venom-induced prothrombin activation by homologous and heterologous antivenoms and EDTA. The effect of antibodies (150 μg) and EDTA (various molarities from 1 μM to 10 mM) on venom-induced prothrombin activation measured by chromogenic assay. Bars represent end-point absorbances (405 nm). Error bars represent SEM of triplicate measurements. Circles represent individual data points. Asterisks indicate significant reductions in activity compared to venom-only measurements: ***P < 0.001, **P < 0.01, *P < 0.05; one-way ANOVA with Tukey’s HSD post hoc test
