Abstract

Human platelets and platelet particulate fractions were found to emit a burst of chemiluminescence during incubation with arachidonic acid. The magnitude of light emission was directly related to the number of platelets in the reaction mixture and varied little for the same individual from day to day. The chemiluminescence response of platelets was localized to the particulate fraction and was almost totally oxygen dependent. In addition to arachidonate, seven other polyunsaturated fatty acids, including several that are not prostaglandin precursors, also induced platelet chemiluminescence.
