Abstract

This study was aimed to prepare immunoradiometric (IRMA) system using solid-phase magnetizable cellulose particles coupled with luteinizing hormone (LH) to determine LH in human serum. The LH-IRMA system was designed through preparation of LH polyclonal antibody (anti-LH), 125I-LH tracer, and LH standards. Production of anti-LH was carried out through immunization of three Balb/C mice with LH-BSA immunogen. Magnetizable cellulose particles were activated using 1,1’-carbonyldiimidazole (CDI) and coupled with purified anti-LH. Optimization and validation of LH-IRMA were undertaken. The results obtained show that the local solid-phase magnetic particle LH-IRMA is a sensitive, specific, precise, and accurate method for measuring the LH concentration in human serum and can be used as a diagnostic tool for some disorders such as infertility in females and impotence in males.

开发测定人血清中促黄体素的免疫放射测定技术
摘要 本研究旨在利用固相可磁化纤维素颗粒与促黄体生成素(LH)联用制备免疫放射测定(IRMA)系统,以测定人血清中的LH。通过制备 LH 多克隆抗体(抗 LH)、125I-LH 示踪剂和 LH 标准品,设计了 LH-IRMA 系统。用 LH-BSA 免疫原免疫三只 Balb/C 小鼠来制备抗 LH。使用 1,1'-carbonyldiimidazole (CDI) 激活可磁化纤维素颗粒,并将其与纯化的抗 LH 相耦合。对 LH-IRMA 进行了优化和验证。结果表明,局部固相磁性颗粒 LH-IRMA 是一种灵敏、特异、精确和准确的测量人体血清中 LH 浓度的方法,可用作女性不孕症和男性阳痿等疾病的诊断工具。
