HPLC separation of brain radioactivity in (A) perfusates, (B) plasma total lipids of vehicle and MEP-treated rats, (C) brain total phospholipids (total PL) of vehicle and MEP-treated rats and (D) phospholipid classes of ¹⁴C-EPA-infused rats at 5 min post infusion. Peak identified was confirmed with authentic standards, GC-MS and GC-FID. No coelution with 16:0 (palmitate) and 22:5n-3 (n-3 DPA) was found. Percent composition of each identified radioactive FA was calculated and used to adjust the radioactivity of the total phospholipids.
