Abstract:
The oxygenated metabolite of linoleic acid, 13(S)-hydroxyoctadecadienoic acid has recently been shown to play a role in cellular regulation. To detect this molecule in biological systems, we recently developed a specific polyclonal antibody. Using this antibody, we report the presence of 13(S)-hydroxyoctadecadienoic acid in human urine, cell culture media, and untreated goat serum for the first time by a specific, sensitive, and rapid enzyme immunoassay. Furthermore, the enzyme linked immunosorbent assay data are verified by gas chromatography/mass spectrometry analysis of the same samples.

While α protons of carboxylic acids absorb at 2–2.5 ppm, β protons absorb further upfield.
Carboxylic acids are easily identified by dissolving them in deuterium oxide, which results in a rapid exchange of the acidic protons with deuterium. This leads to the disappearance of the acidic...
