Pretreatment with non-labeled PMSF decreased 33-40% of the trapped radioactivities in the brain and other organs in mice. However, regional distribution of [35S]PMSF in rat brain didi not correlate well withthat of AchE activity, suggesting that tha selectivity of PMSF toward AchE may be insufficient for use as an in vivo tracer mapping AchE.}, pages = {991--992}, title = {Evaluation of Phenylmethanesulfonyl fluoride (PMSF) as a Tracer Candidate Mapping Acetylcholinesterase In Vivo}, volume = {20}, year = {1993} }
