摘要
Prostaglandins E1 (alprostadil), E2 (dinoprostone), F1a, and F2a (dinoprost) were characterized in terms of binding to human serum, albumin, -globulin II, β-globulin III, -globulin IV-1, and -globulin IV-4. By using equilibrium dialysis and tritium-labeled ligands, the percent binding for all four ligands was found to decrease in the following order: human serum, albumin, and -globulin IV-4. For the other three proteins, the order was not consistent with the four ligands, and <10% binding was observed. In general, prostaglandins E1 and E2 showed a higher percent binding for all fractions than prostaglandins F1a and F2a. All four ligands can be characterized as showing significant binding to human serum, albumin, and -globulin IV-4.

前列腺素E 1(前列地前列腺素),E 2(dinoprostone),F 1a和F 2a(依诺前列素)的特征在于与人血清,白蛋白,球蛋白II,β-球蛋白III,球蛋白IV-1和 - 球蛋白IV-4。通过使用平衡透析和氚标记的配体,发现所有四种配体的结合百分比按以下顺序降低:人血清,白蛋白和球蛋白IV-4。对于其他三种蛋白质,顺序与四种配体不一致,观察到10%结合。通常,前列腺素E 1和E 2显示出比前列腺素F 1a和F 2a对所有级分的结合百分比更高。所有四种配体可以表征为显示与人血清,白蛋白和球蛋白IV-4的显着结合。
