Figure 6: Reciprocal variation of AChE and pseudoChE activities, extrapolated from Figure 5. The term pseudocholinesterase refers to the activity remaining in samples preincubated with and incubated in the [7] medium containing 10−5 M BW284c51. -axis = μmoles of AcTCh cleaved in 3 mins; white columns: no inhibitors added; grey columns: residual activity after exposure to BW284c51.
