东方海洋大健康研制出新型冠状病毒抗体检测试剂盒
日前,东方海洋大健康旗下东方海洋(北京)医学研究院研发团队研制出新型冠状病毒抗体检测试剂盒(酶联免疫法),试剂盒性能初步验证结果显示具备优异的灵敏度和特异性。目前国内尚无已获批的同类产品。自新型冠状病毒感染的肺炎疫情爆发以来,东方海洋(北京)医学研究院科研团队立即投入到新型冠状病毒抗体检测试剂盒的研发工作之中,从基因工程抗原制备纯化入手,以最快速度获得高效表达的高活性基因工程NP抗原,并在此基础上同时研制出2019-nCoV新型冠状病毒IgM抗体检测试剂盒(酶联免疫法)和新型冠状病毒IgG抗体检测试剂盒(酶联免疫法)。上述检测试剂盒可以实现在1.5个小时内完成96人份样本的高通量检测,采用的血清学检查是临床常用的诊断方法,更为简便快捷,且更适用于基层医疗机构进行早期筛查与辅助诊断。由于IgM在新型冠状病毒感染者发病早期或急性期即可检测到,部分病例甚至在潜伏末期即可检测到,因此对感染者进行IgM抗体检测可以实现早期诊断。在应对疫情爆发时,最短时间内可以有效实现对大量与病人密切接触的高危人群及疑似病例的筛查。与此同时,对于处在感染期及恢复期的患者进行血清IgG抗体的检测以及连续血清抗体检测和临床观察,可以有助于了解病毒消除规律,并用于大规模流行病学调查以及流行病学珍贵数据的获得。目前,新型冠状病毒抗体检测试剂盒(酶联免疫法)已经完成初步临床评价,并即将启动注册申报相关工作。东方海洋大健康现阶段将免费提供上述检测试剂盒,用于新型冠状病毒感染的肺炎病例的辅助诊断以及相关科研工作的需要。
