The original data were given as mean +/− standard error of the mean (SEM), but intentionally omitted SEM for clarity. a 50% inhibitory concentration (means of at least 3 independent experiments) of eeAChE from electric eel; b 50% inhibitory concentration (means of at least 3 independent experiments) of eqBuChE from equine serum; c Selectivity Index for AChE = IC50 (BuChE)/IC50 (AChE).
