  • Patent number: 6440682
    Abstract: A method to assess hypertension by measuring the amount of free and conjugated hydroxyeicosatrienoic acids (DHETS) and metabolites of DHETs, which are metabolites of arachidonic acid (AA) epoxygenases and epoxide hydrolases, in a biological sample which contains the DHETs (using any methods including GC/MS or ELISA) is disclosed. The method further included determining the amount of molecules containing a DHET-specific epitope immunoreactive with antibodies produced against DHETs present in the sample. This amount is compared with a control sample(s). Hypertension is determined through the comparison wherein the amount of increase of free and conjugated DHETs and metabolites of DHETs in the sample isolated from an organism. The present invention also provides a method to assess catalytic activity of AA epoxygenases using immunoassays by measuring the amounts of NADPH-independent epoxyeicosatrienoic acids (EETs) and total (NADPH-dependent+independent) EETs.
