- Abstract:
- Stable isotope dilution gas chromatography-mass spectrometry provides one of the most important techniques for the quantitative measurement of eicosanoids. This technique was applied to the quantitation of hydroxyeicosatetraenoic acids, hydroxyheptadecatrienoic acid, thromboxane B2 and prostaglandin F2 alpha formed during platelet aggregation after stimulation of gel-filtered platelets with thrombin (0.25 U/ml) or collagen (2 micrograms/ml). Similar amounts of hydroxyheptadecatrienoic acid and thromboxane B2 were found after platelet activation. The ratio of formation of 12-hydroxyeicosatetraenoic acid to thromboxane B2 varied from donor to donor. Only small amounts of prostaglandin F2 alpha (up to 200 pg per 2.0.10(8) platelets) and basic values of 15-hydroxyeicosatetraenoic acid (up to 100 pg per 2.0.10(8) platelets) were measured using gas chromatography with negative ion chemical ionization mass spectrometry. In addition, different stable isotope dilutions were prepared and are discussed in detail.
