A novel time-resolved immunofluorometric method is described for the estimation of human luteinizing hormone (LH) in serum and urine. The method utilizes two monoclonal antibodies: one reacting with the beta-subunit is adsorbed to the wall of a microtiter well, and the other is labeled with a fluorescent europium chelate and reacts with the alpha-subunit. The method is ultrarapid (15-30 min) and highly sensitive (1 IU/L). A large linear measuring range allows measurement of LH levels from 1 to 250 IU/L. For the monitoring of urinary LH, IFMA gives the same information as the Hi-Gonavis assay, but it has the advantages of greater sensitivity and a shorter assay time. For the determination of serum LH levels, an acceptable correlation was observed between radioimmunoassay and IFMA. Furthermore, IFMA has a greater sensitivity, and is more rapid and not dependent on the handling of radioactive materials.
本文描述了一种用于测定血清和尿液中人类促黄体生成素(LH)的新型时间分辨免疫荧光测定法。该方法使用两种单克隆抗体:一种与β亚基反应,吸附于微量滴定孔壁上,另一种用荧光铕螯合物标记,与α亚基反应。该方法超快速(15 - 30分钟)且高度灵敏(1 IU/L)。较大的线性测量范围允许测量1至250 IU/L的LH水平。对于监测尿LH,免疫荧光测定法(IFMA)与Hi - Gonavis检测法提供相同信息,但它具有更高灵敏度和更短检测时间的优点。对于测定血清LH水平,放射免疫测定法与IFMA之间观察到可接受的相关性。此外,IFMA具有更高的灵敏度,更快,且不依赖于放射性物质的处理。
