“ Bradykinin was found to stimulate very potently arachidonic acid release from cells prelabelled with [3H]arachidonate , the response being dose-dependent and half-maximal at 8 ng/ml.”
“The rate of release of label (primarily arachidonate ) from cells was increased by bradykinin (100 ng/ml) approximately 8-fold, with a return to control levels by 10 min.”
