title: The pH-dependence of chloroquine uptake by phosphatidylcholine vesicles.
abstract: The pH-dependence of chloroquine uptake by phosphatidylcholine bilayered vesicles was investigated to examine the relative affinity of ionized and un-ionized chloroquine species to membrane bilayers. The results suggest that the neutral species and monocation are taken up by the bilayers but only the un-ionized species interacts significantly with the hydrocarbon interior.
