Analysis of cerebrospinal fluid (CSF) offers key insight into the status of the CNS. Characterization of murine CSF proteomes can provide a valuable resource for studying CNS injury and disease in animal models. However, the small volume of CSF in mice has thus far limited individual mouse proteome characterization. Through nonterminal CSF extractions in C57Bl/6 mice and high-resolution 2D-LC MS/MS analysis of individual murine samples, we report the most comprehensive proteome characterization of individual murine CSF to date. We identified a total of 566 unique proteins, including 128 proteins from three individual CSF samples that have been previously identified in brain tissue. Our methods and analysis provide a mechanism for individual murine CSF proteome analysis. The data are available in the ProteomeXchange with identifier PXD000248 (http://proteomecentral.proteomexchange.org/dataset/PXD000248).
脑脊液(CSF)分析为了解中枢神经系统(CNS)的状态提供了关键见解。对小鼠脑脊液蛋白质组进行表征可为在动物模型中研究中枢神经系统损伤和疾病提供宝贵资源。然而,小鼠脑脊液的量较少,这限制了对单个小鼠蛋白质组的表征。通过对C57Bl/6小鼠进行非终末期脑脊液提取,并对单个小鼠样本进行高分辨率二维液相色谱串联质谱(2D-LC MS/MS)分析,我们报告了迄今为止单个小鼠脑脊液最全面的蛋白质组表征。我们总共鉴定出566种独特蛋白质,其中包括来自三个单个脑脊液样本的128种蛋白质,这些蛋白质先前已在脑组织中被鉴定出来。我们的方法和分析为单个小鼠脑脊液蛋白质组分析提供了一种机制。数据可在蛋白质组交换库中获取,标识符为PXD000248(http://proteomecentral.proteomexchange.org/dataset/PXD000248)。
