Purification and high-resolution MS of lipids generated by oxidation of arachidonate to isolate the synthetic lipid. A, semipreparative normal-phase HPLC as indicated in under “Experimental procedures” with collected fractions labeled A–D. The HPLC was monitored online at 206 nm. B, further HPLC purification of Peak B (Fig. 1A) as indicated under “Experimental procedures.” The HPLC was monitored online at 206 nm. C, high-resolution (Orbitrap) LC-MS/MS of platelet lipid (top) versus Peak B (bottom) as indicated under “Experimental procedures.” mAU, milli-absorbance units.
