| 摘 要： | 腹泻性贝毒是一类分布较广的赤潮毒素,严重威胁到人类的健康和安全。本文用胶体金标记利用细胞融合技术制备的抗软海绵酸单克隆抗体,使用卵清蛋白合成高偶联比的包被抗原,以硝酸纤维素膜为载体,利用免疫层析技术原理,建立了快速检测软海绵酸的免疫层析试纸条方法。方法检出限12 ng/mL(0.96纳克/条)。

| Abstract: | A competitive gold immunochromatography assay for okadaic acid(OA) was developed in this paper.The colloidal gold particles were coated with purified monoclonal anti-OA antibodies prepared by cell fusion.The capture reagent in the assay was an OA-ovalbumin conjugate immobilized on the lateral flow membrane of the test device.The detection limit of the rapid test strip was 12 ng/mL.The method was fast and simple.The results could be obtained within 15 min and all reagents were included in the test device.Oth... |
