A new method for preparation of Hb solution free of stromal lipid was described. Almost all the lipid in fresh hemolysate of bovine red blood was removed with hydrophobic interaction chromatography (HIC) in the presence of 2% PEG4000, 5% PEG4000, 2%PEG10000 or 5%PEG10000. With the adding of 5%PEG4000, the 80% of recovery of Hb in HIC was obtained and the maximum lipid absorbed by hydrophobic medium, butyl agarose -6B was 86.6 mg/mL. The activity (P50) of hemoglobin preparation was 3386.4 Pa torrs, and the Hill number was 2.54, which were near to that of the native red blood cells. The mechanism of removing lipid by HIC and the function of PEG in the process were discussed.
