sampling human indigenous saliva peptidome using a lollipop-like ultrafiltration probe: simplify and enhance peptide detection for clinical mass spectrometry

虽然人类唾液蛋白质和多肽已显示1-2 majorly确定从唾液蛋白的胰蛋白酶消化。土著人的唾液多肽的鉴定没有事先与外源酶消化成为当务之急，因为在人类唾液中的原生肽提供的潜在价值，为诊断疾病，预测疾病的进展，并监测治疗效果。适当的采样是提高土著人的唾液多肽鉴定的关键一步。抽样涉及人类唾液离心去除碎片3-4传统方法可能太费时，是适用于临床使用。此外，通过离心去除碎片可能无法清理，大部分受感染的病原体和去除高丰度蛋白质，常常阻碍了鉴定低丰度多肽。 传统的蛋白质组学方法，PRI共轭玛利莲利用二维凝胶电泳（2-DE）凝胶与凝胶消化能找出很多的唾液蛋白质5-6。然而，这种方法一般是不够敏感的检测低丰度的肽/蛋白质。液相色谱 - 质谱（LC-MS法）为基础的蛋白质组学是一种替代，它可以识别2-DE分离，恕不另行蛋白质。虽然这种方法提供了更高的灵敏度，它一般需要事先样品预分馏7预消化和胰蛋白酶，这使得它难以用于临床。 规避由于样品制备质谱的障碍，我们已经开发出一种技术叫做毛细管超滤（CUF）探针8-11。从我们的实验室数据表明，的CUF探测器能够捕捉各种动物在一个充满活力和微创的方式8微环境的蛋白质在体内 -11。没有离心是必要的，因为通过简单的样品采集过程中撤回注射器负压创建。 CUF探针结合的LC-MS已成功确定了胰蛋白酶消化的蛋白质8-11。在这项研究中，我们创建一个棒棒糖般的超滤（LLUF）探头，可以很容易地适合于人类口腔升级的超取样技术。没有胰蛋白酶消化的LC-MS直接分析表明，人类唾液本国包含许多肽来自各种蛋白质的片段。 LLUF探头采样唾液避免离心，但有效地消除了许多大型及高丰度蛋白。质谱结果表明，许多低丰度肽后，筛选出较大的蛋白质与LLUF探针检测。多步样品色谱分离检测低丰度唾液肽独立。为临床应用，LLUF探头纳入D可以用LC-MS在未来可能被用来从唾液，以监测疾病的进展。
