Figure Lengend Snippet: A ) The serine protease (SVSP) activity of individual venoms and the venom immunogen mixtures displayed as the rate of cleavage (absorbance/time) of the chromogenic substrate. B ) Inhibition of venom serine protease activities by the EAVs displayed as the percentage reduction of venom only activities from ( A ). Also see and Figs. C) The metalloproteinase (SVMP) activity of individual venoms and the venom immunogen mixtures displayed as the area under the curve (AUCs) resulting from cleavage of a fluorescent substrate over time. D) Inhibition of venom metalloproteinase activities by the EAVs displayed as the percentage reduction of venom only activities from ( C ). See also and Figs. E) The coagulopathic activity of individual venoms and the venom immunogen mixtures displayed as the AUCs resulting from increases in absorbance stimulated by clotting over time. F) Inhibition of coagulopathic venom activities by the EAVs displayed as the percentage reduction of venom only activities from ( E ). See also and Figs. For all data shown, data points represent means of triplicate readings, and error bars represent standard error of the mean (SEMs).
Article Snippet: The SVMP assay kinetically measured cleavage of a quenched fluorogenic substrate (ES010, R&D Biosystems) by venom in the presence or absence of inhibitors.
