可视化突触的纳米组织是阐明神经系统结构-功能关系的基础。超分辨率显微镜的出现提供了一种评估和量化突触处众多蛋白质动态组织的工具。在这里,我们提出了一个协议,评估抑制性突触支架蛋白,桥蛋白,在大鼠原代海马培养使用dSTORM显微镜。我们描述了青蒿素治疗,免疫细胞化学,dSTORM图像采集,单分子定位和突触支架蛋白动力学分析的步骤。有关本方案使用和执行的完整详细信息,请参见Guzikowski和Kavalali(2022)。使用dSTORM显微镜评估抑制性突触支架蛋白桥蛋白的方案原代海马培养物染色的免疫细胞化学步骤dSTORM成像和突触前和突触后蛋白的单分子定位研究突触簇及其空间分布的图像分析出版商说明:进行任何实验方案都需要遵守当地机构的实验室安全和伦理指南。可视化突触的纳米组织是阐明神经系统结构-功能关系的基础。超分辨率显微镜的出现提供了一种评估和量化突触处众多蛋白质动态组织的工具。在这里,我们提出了一个协议,评估抑制性突触支架蛋白,桥蛋白,在大鼠原代海马培养使用dSTORM显微镜。我们描述了青蒿素治疗,免疫细胞化学,dSTORM图像采集,单分子定位和突触支架蛋白动力学分析的步骤。
Visualizing the nano-organization of the synapse is fundamental to elucidating the structure-function relationship of the nervous system. The advent of super-resolution microscopy provides a tool to assess and quantify the dynamic organization of numerous proteins at the synapse. Here we present a protocol assessing inhibitory synapse scaffold protein, gephyrin, in rat primary hippocampal cultures using dSTORM microscopy. We delineate the steps for artemisinin treatment, immunocytochemistry, dSTORM image acquisition, single-molecule localization, and the analysis of synaptic scaffold protein dynamics. For complete details on the use and execution of this protocol, please refer to Guzikowski and Kavalali (2022). Protocol to assess inhibitory synapse scaffold protein gephyrin with dSTORM microscopy Immunocytochemistry steps for staining primary hippocampal cultures dSTORM imaging and single-molecule localization of pre- and post-synaptic proteins Image analysis to investigate synaptic clusters and their spatial distribution Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
