Effect of anti-II MoAb and LA IgGs on binding of II to phospholipid vesicles. Binding of prothrombin to 200 nm 74:25:1 DOPC:DOPS:biotin-DHPE unilamellar vesicles was measured by separating bound from free prothrombin in an air-fuge.22 (A) Effect of control MoAb or anti-II MoAb on binding of 0.1 μmol/L prothrombin to phospholipid vesicles. The data are expressed as the fraction of total prothrombin bound. Data points and error bars represent the mean and SE of 3 experiments. (B) Effect of control or LA IgGs on binding of 0.1 μmol/L prothrombin to phospholipid vesicles. The data are expressed as the fraction of total prothrombin bound.
