摘要 开发了一种酶联免疫吸附测定 (ELISA),用于测定人血浆中的凝血酶-抗凝血酶 III 复合物 (TAT)。该测试系统遵循夹心原理,使用两种不同的抗体,分别针对人凝血酶和人抗凝血酶III。抗体选择性地结合 TAT 的相应抗原部分。该测定用添加到缺乏 TAT 的血浆中的一定浓度的预制纯化 TAT 进行校准。测定的灵敏度下限为0.5 μg/1。 TAT 浓度在 2 至 60 μg/1 之间时,平均变异系数为 4.2%(测定内)和 3.5%(测定间)。根据 88 名健康捐献者血浆样本中的 TAT 浓度计算出 0.85 至 3.2 μg/1 的参考范围(平均值 ± SD:1.45 ± 0.4 μg/I)。在肺栓塞患者 (n = 17) 的血浆样本中,测量到 TAT 浓度在 3 至 25 μg/1 之间。在 15 名深静脉血栓患者中,发现 TAT 高达 3 至 25 μg/1。根据这些数据,我们得出结论,TAT 的测量可能是特异性检测凝血途径潜在激活的敏感参数。
Summary An enzyme-linked immunosorbent assay (ELISA) was developed for the determination of thrombin-antithrombin III complex (TAT) in human plasma. The test system follows the sandwich principle and uses two different antibodies directed against human thrombin and human antithrombin III, respectively. The antibodies bind selectively to the corresponding antigen moieties of TAT. The assay was calibrated with definite concentrations of preformed purified TAT added to TAT-poor plasma. The lower limit of sensitivity of the assay was 0.5 μg/1. Mean coefficients of variation of 4.2% (intraassay) and 3.5% (interassay) were found for TAT concentrations between 2 and 60 μg/1. A reference range from 0.85 to 3.2 μg/1 was calculated from TAT concentration in plasma samples from 88 healthy donors (mean value ± SD: 1.45 ± 0.4 μg/I). In plasma samples from patients with pulmonary embolism (n = 17), TAT concentrations between 3 and 25 μg/1 were measured. In 15 patients with deep vein thrombosis, TAT was found up to 3 to 25 μg/1. From these data we conclude that measurement of TAT can be a sensitive parameter for specific detection of a latent activation of the clotting pathway.
