Used in research settings to quantify levels of Prostaglandin D2 (PGD2) metabolites in biological samples such as plasma, serum, or tissue homogenates. Particularly useful in studies related to allergic responses, asthma, and inflammatory diseases where PGD2 plays a key signaling role. The MOX derivative detection allows for stable and accurate measurement of PGD2 pathway activity. Commonly applied in immunology and pharmacology research to evaluate mast cell activation and the efficacy of drugs targeting prostaglandin pathways. Not intended for diagnostic use.
