Abstract
Eicosanoids are arachidonic acid metabolites formed through the cyclooxygenase or one of the lipoxygenase metabolic pathways. They include the prostaglandins (PG), leukotrienes (LT), thromboxanes (Tx), peptidoleukotrienes, and 5-hydroxyeicosatetraenoic acid (5-HETE). This unit describes procedures for measuring individual eicosanoids using several commercial kits. These include kits for an enzyme immunoasssay (ELISA) and a radioimmunoassay (RIA). A method is also described that can be used to analyze the full range of eicosanoids produced in a biological system, and a support protocol presents an acetone/chloroform extraction method for purifying eicosanoids prior to assay. Another support protocol describes a different extraction protocol in which samples are run over an octadecylsilyl silica column.
