Surface plasmon resonance (SPR) is one of the commonly used technologies for detailed and quantitative studies of protein-protein interactions and determination of their equilibrium and kinetic parameters. SPR provides excellent instrumentation for a label-free, real-time investigation of protein-protein interactions. SPR是用来进行实时分析,简单快捷的监测DNA与蛋白质之间、蛋白质与蛋白质之间、药物与蛋白质之间、核酸与核酸之间、抗原与抗体之间、受体与配体之间等等生物分子之间的相互作用。SPR在生命科学、医疗检测、药物筛选、食品检测、环境监测、毒品检测以及法医鉴定等领域具有广泛的应用需求。
