摘　　要：通过综述基于过氧化物酶和生物素连接酶的邻近标记技术的原理、应用及常见问题,重点回顾目前邻近标记技术在神经生物学领域主要用于突触亚区分子成分的研究并取得一些成果,分析在应用过程中面临的活体脑组织中探针输入和高背景等挑战。展望该技术将为系统地鉴定神经组织中高度复杂的动态相互作用蛋白质组及亚细胞结构蛋白质组提供前所未有的机会,也为寻找神经生物学中的关键分子提供有效途径。The principle,application and common problems of peroxidase-based PL and biotin ligase-based PL are introduced.This review focuses on the current application of PL technique in the study of synaptic subregion molecular components in the field of neurobiology and its achievements,and analyzes the challenges faced in the application process,such as probe input and high background in living brain tissue.It is pointed out that this technique will provide an unprecedented opportunity to systematically identify the highly complex proteome of dynamic interaction and subcellular structure in neural tissue,and also provide an effective approach to search for key molecules in neurobiology.
