Oxidation does not enhance PC-PtGla activity. PE/PS/PC phospholipid liposomes were oxidized with copper sulfate as described in “Materials and methods,” and plasma clotting was measured. Error bars indicate the SE of 3 determinations. □, 0.2 μg/mL APC-PtGla added; □, 0.2 μg/mL APC added; ○, no additions.
