Detection of severe acute respiratory syndrome (SARS) coronavirus nucleocapsid protein in human serum using a localized surface plasmon coupled fluorescence fiber-optic biosensor.
为增强常规免疫分析技术检测严重急性呼吸综合征冠状病毒(SARS-CoV)核衣壳蛋白(N蛋白)的灵敏度,作者开发了一种局域表面等离子体耦合荧光(LSPCF)光纤生物传感器,将夹心免疫分析与LSP技术相结合。实验中,在缓冲液中重组SARS-CoV N蛋白(GST-N)浓度与荧光信号在0.1 pg/mL至1 ng/mL范围内呈线性关系;在...
