The objective of this study was to determine the transcellular metabolism of leukotriene A4 by rabbit blood cells. mixed peripheral blood leukocyte preparations with and without platelets in a ratio of 1:40 were challenged with the Ca(2+)-ionophore A23187. 5-Lipoxygenase metabolites production was assessed by RP-HPLC coupled with diode-array UV detection. https://www.roneverhart.com/9725/
