Binding experiments were carried out as described in Table 1, except that IOVs were incubated with hemolysates of different sources. The numbers show the amount of the bound TPI in ng/mg IOV. Expt. A, 300 μl of hemolysate; Expt. B, 700 μl of hemolysate. The standard error of the determinations was ± 15% (n = 3).
