[Abstract]  We developed a protocol for photoconversion of endocytic marker FM1-43 followed by electron microscopy analysis of synaptic boutons at the Drosophila neuromuscular junction. This protocol allows detection of stained synaptic vesicle even when release rates are very low, such as during the spontaneous release mode. The preparations are loaded with the FM1-43 dye, pre-fixed, treated and illuminated to photoconvert the dye, and then processed for conventional electron microscopy. This procedure enables clear identification of stained synaptic vesicles at electron micrographs. [摘要]  我们开发了内吞标记FM1-43的光转换方案,然后在果蝇神经肌肉接头处进行突触引物的电子显微镜分析。 即使在释放速率非常低时,例如在自发释放模式期间,该方案允许检测染色的突触小泡。 该制剂装载有FM1-43染料,经预先固定,处理和照射,以使染料转变为染料,然后进行常规电子显微镜处理。 该方法能够在电子显微照片下清楚鉴定染色的突触小泡。
【背景】神经元发射体通过突触小泡与神经元质膜的融合而释放。囊泡可以自发融合或响应动作电位。随后,囊泡通过内吞作用获得回收。通过分子生物学,电生理学和显微镜的工具广泛研究了突触小泡回收的分子机制(Slepnev和De Camilli,2000; Sudhof,2004; Rizzoli和Betz,2005; Kavalali,2006)。加载内参标记FM1-43与染料光转换耦合,然后进行电子显微镜分析是一种强大的技术,允许调查和测量回收囊泡池(Harata et al。,2001; Schikorski and Stevens,2001; Rizzoli和Betz, 2004)。果蝇神经肌肉接头(NMJ)是具有明确定义的突触引物的有利制剂,其能够快速产生具有突变突触蛋白的细胞系和严格评估囊泡回收池(Akbergenova和Bykhovskaia,2009; ...

[Abstract]  Transmission electron microscopy is a technique for observing the fine details of organelles in cells or tissues. This protocol is to be used to exam the membrane structure in cells with or without virus infection. Modifications should be made if users want to get images from tissues. [摘要]  透射电子显微镜是用于观察细胞或组织中细胞器的细节的技术。 该协议用于检查有或没有病毒感染的细胞中的膜结构。 如果用户想要从组织获得图像,应该进行修改。
