Notes: The deuterated arachidonic acid oxylipin MaxSpec® LC-MS Mixture contains deuterated forms of oxylipin metabolites derived from arachidonic acid (Item No. 90010). The mixture is supplied in an amber ampule in which the headspace has been purged with argon to prevent lipid oxidation. This product has been designed for direct use in LC-MS applications. This mixture is ideally suited for use as an internal standard in mass spectrometry applications. After opening, we recommend that the mixture be transferred immediately to a 1 ml glass screw cap vial, to prevent solvent evaporation, and stored at -20°C. The mixture should be discarded after multiple freeze/thaw cycles.This mixture contains 5(S)-HETE-d8 (Item No. 334230), 12(S)-HETE-d8 (Item No. 334570), and 15(S)-HETE-d8 (Item No. 334720). The unmodified forms are involved in the immune response.
