A solution containing dLDL (1.2 mg protein/ml) and ferric-Hb (12 µM) was incubated in presence or absence of Hp 2-2 (13 µM). LDL fractionation by charge following 3.5 hours of incubation was performed by fast anion exchange liquid chromatography. 1: dLDL alone (control); 2: dLDL+ferric Hb; 3: dLDL+ferric Hb+Hp; 4: Hp alone (control). A representative result of 4 independent experiments is shown.
