使用三通道双报告基因荧光流分析系统开发了一种基于微珠的多重免疫测定法,该测定法可同时评估血清样本中针对欧洲和北美导致莱姆疏螺旋体病的不同 疏螺旋体 属的多种抗原引发的 IgG 和 IgM。

莱姆疏螺旋体病的诊断方法尽管经过多年的研究调查,但仍不理想,并且缺乏敏感性。通过我们的双报告多重疏螺旋体检测,我们可以鉴定针对不同疏螺旋体物种的免疫反应性,以辨别患者样本中的早期 IgM 和后来更持久的 IgG 免疫反应性。Luminex 的 Intelliflex 仪器具有多路复用功能,结合其双报告系统,是最先进的技术之一,可使用少量供体材料最大限度地提高信息输出。

双报告基因免疫测定方法通过同时检测针对人血清样本中任何已实施的疏螺旋体抗原的 IgG 和 IgM 抗体来改进传统免疫测定。通过这种方式,我们可以在一次检测运行中从有价值的样品材料中提取的信息增加一倍。我们的方法可同时对早期感染阶段和后期更持久的免疫反应性进行决定性的疏螺旋体鉴定和灵敏检测。

从而实现成本、材料和时间效率,以及更精确地检测莱姆疏螺旋体病感染。我们的检测支持全球血清监测和病原体消除策略,以确定区域物种分布和感染源。我们的实验室参与了针对多种病毒病原体的预防和治疗性疫苗开发,特别关注疫苗与感染免疫反应的血清学鉴别以及深度免疫反应表征。
