描述：

Synaptophysin (D35E4) XP® Rabbit mAb 兔单抗识别内源性的synaptophysin 总蛋白。共聚焦免疫荧光分析可见到一些核背景染色。该单克隆抗体由合成的人类synaptophysin蛋白Ala230位点附近肽段免疫动物而制成。Synaptophysin（SYP）是一种神经突触小泡糖蛋白，在神经内分泌细胞和肿瘤中表达，从而可作为肿瘤诊断标志物使用（1）。Synaptophysin含有4个跨膜结构域，形成一个六聚体通道或缝隙连接样的孔（2）。Synaptophysin结合到SNARE蛋白，synaptobrevin/VAMP，防止突触小泡融合复合体中的synaptobrevin包涵体形成，创造synaptobrevin的储备库以供突触活动的增加时使用（3）。Synaptophysin也负责synaptobrevin 2/VAMP2定位至突触小泡，其为融合复合物的关键组分（4）。

Specificity / Sensitivity

Synaptophysin (D35E4) XP® Rabbit mAb detects endogenous levels of total synaptophysin protein. Some nuclear background staining was observed by confocal immunofluorescent analysis.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide surrounding Ala230 of human synaptophysin protein.

Background

Synaptophysin (SYP) is a neuronal synaptic vesicle glycoprotein that is expressed in neuroendocrine cells and neoplasms, and thus can be used as a marker in tumor diagnosis (1). Synaptophysin contains four transmembrane domains that form a hexameric channel or gap junction-like pore (2). Synaptophysin binds to the SNARE protein synaptobrevin/VAMP, which prevents the inclusion of synaptobrevin in the synaptic vesicle fusion complex and creates a pool of synaptobrevin for exocytosis when synapse activity increases (3). Synaptophysin is also responsible for targeting synaptobrevin 2/VAMP2 to synaptic vesicles, a critical component of the fusion complex (4).
