Anti-Müllerian hormone (AMH) is known as a reliable marker of ovarian reserve (OR). The determination of AMH is of great importance and most existed AMH detection methods are heterogeneous immunoassay. In this study, a novel homogeneous sandwich immunoassay-light-initiated chemiluminescence assay (LICA) for detecting AMH serum level was developed. This AMH-LICA was performed by incubating serum samples with AMH mouse monoclonal antibody coated with chemibeads, streptavidin-coated sensibeads, and biotinylated AMH mouse monoclonal antibody. Sensitivity, precision, accuracy and cross-reactivity of this assay were evaluated. Besides, a regression analysis showed a high correlation between AMH-LICA and Roche Elecsys® AMH assay (y = 0.9851x + 0.07147, R = 0.9569). As a homogeneous immunoassay, this AMH-LICA could accurately and rapidly determine the serum level of AMH with high-throughput. Thus, this new developed assay may be a new useful analytical tool for the determination of AMH.
抗缪勒管激素 (AMH) 是一种公认的卵巢储备功能 (OR) 的可靠标志物。AMH 的测定具有重要意义,目前大多数 AMH 检测方法都是异质免疫测定法。本研究开发了一种新型的均相夹心免疫分析-光引发化学发光法 (LICA) 来检测 AMH 血清水平。该 AMH-LICA 通过将血清样本与包被有 AMH 单克隆抗体的化学珠、链霉亲和素包被的感测珠和生物素化 AMH 单克隆抗体孵育来进行。评估了该检测方法的灵敏度、精密度、准确度和交叉反应性。此外,回归分析显示 AMH-LICA 与罗氏 Elecsys® AMH 检测法具有高度相关性 (y = 0.9851x + 0.07147, R = 0.9569)。作为一种均相免疫测定法,该 AMH-LICA 可高通量、准确、快速地测定 AMH 的血清水平。因此,这种新开发的检测方法可能是 AMH 测定的一种新的有用分析工具。
