Determination of prostaglandins and thromboxane in whole blood by high-performance liquid chromatography with fluorimetric detection.

A highly sensitive and specific assay for the quantitation of prostaglandins (PGs) such as PGE1, PGE2, PGF1 alpha, PGF2 alpha, 6-keto-PGF1 alpha, and including thromboxane B2, is described. The method involves the addition of PGF1 alpha and PGE1 as the internal standards, extraction from whole blood and purification by silica gel column chromatography. Following conversion into the methoximes, purification by reversed-phase chromatography and esterification with panacyl bromide, samples are analysed by high-performance liquid chromatography with fluorimetric detection. The lower limit of detection of the eicosanoids 6-keto-PGF1 alpha, thromboxane B2 and PGF2 alpha in blood is ca. 50 pg/ml and that of PGE2 is 100 pg/ml. Assay linearity is demonstrated over a range from 60 pg to 60 ng of eicosanoid injected. The method allows simultaneous assessment of prostaglandins and thromboxane extracted from complex biological fluids at picogram levels.[1]
