概括。使用针对激肽释放酶裂解的 HMWK 轻链和重链的抗体开发了人高分子量激肽原 (HMWK) 和低分子量激肽原 (LMWK) 的放射免疫测定法。使用抗轻链抗体,放射免疫分析对 HMWK 具有特异性,检测限为 0.4 ng。抗重链抗体用于定量总激肽原抗原的浓度。在四种先天性 HMWK 促凝血活性缺陷的血浆中,有 2 例未检出抗原,其他血浆中检出微量抗原,低于 1 μg/ml(正常浓度:72 ± 6 μg/ml)。在没有 HMWK 的情况下,使用抗重链抗体进行的放射免疫测定对 LMWK 具有特异性。这些患者血浆中的 LMWK 含量各不相同,从检测不到抗原(即低于 0.15 μg/ml)到正常含量。
Summary. Radioimmunoassays of human high molecular weight kininogen (HMWK) and low molecular weight kininogen (LMWK) were developed using antibodies directed against the light and the heavy chains of kallikrein‐cleaved HMWK. With the anti‐light chain antibodies, the radioimmunoassay was specific for HMWK with a detection limit of 0.4 ng. The anti‐heavy chain antibodies were used to quantify the concentration of total kininogen antigens. In four different plasmas with a congenital deficiency in HMWK procoagulant activity, there was no detectable antigen in two cases and trace amounts, less than 1 μg/ml in the other plasmas (normal concentration: 72 ± 6 μg/ml). In the absence of HMWK, the radioimmunoassay performed with the anti‐heavy chain antibodies was specific for LMWK. The amount of LMWK was different in each of these patients’plasmas, ranging from no detectable antigen, i.e. less than 0.15 μg/ml, to a normal content.
