The subcellular localization of ubiquinone in human neutrophils

Abstract
The subcellular localization of ubiquinone; it was detected only in the mitochondrial fractions. It was not enriched in phagolysosomes which were enriched in O2- generating activity and cytochrome b-245. Thus, ubiquinone is unlikely to play a direct role in the electron transport chain located in the plasma membrane which functions to produce microbicidal oxygen radicals.
